Indicates a situation which, if not observed and handled properly, could result in injury or property damage.

: This is a mark to call attention to the reader.

- Before starting disassembly/reassembly or mechanical adjustment, be sure to disconnect the power cord from the power source.

- Do not replace a fuse with the power switch turned on. - When replacing a fuse, use the same rating and type since it is provided to prevent

fire and damage to the “Unit, Power Supply”.

- Do not disassemble/reassemble or adjust the machine, if it functions properly. Particularly, do not loosen screws on any component, unless necessary. - After completing an inspection and before turning on the power, be sure to check that

there is no abnormality. - Never try to print without media. - Check that the media is properly set. - Do not lay anything on the cover or lean against it during maintenance or while the

printer is in operation. - During maintenance, be careful not to leave parts or screws unattached or loose

inside the printer. - When handling a printed circuit board, do not use gloves, etc., which can easily

cause static electricity. Since ICs, such as CPU, RAM and ROM, might be destroyed by static electricity, do not touch lead wires or windows unnecessarily.

- Do not put the printed circuit boards directly on the printer or on the floor. - When disassembling or reassembling, check wires for any damage and do not pinch

or damage them. Also, run wires as they were.

CL-S621, CL-S621C & CL-S631 1-10

1-4. Adjustable Sensors There are two media sensors; the upper sensor (transparent sensor) and the bottom sensor (reflective sensor). The upper sensor is used to detect the labels on the liner or the U-shaped notches of tag. The bottom sensor is used to detect the black marks on tag. Also, both sensors are used to detect media end. The mechanical adjustable range of both sensors is equal and they are adjustable independently. When both sensors are moved to the left end or the right end (center of the printing mechanism), both sensors coincide for detecting notch or label. For details about the media sensors, refer to “2-1-3 Label/Tag Detection Mechanism".

2-1-2. Media Feed Mechanism The major components of the media feed mechanism are: (a) SA, Motor (b) SA, Platen (c) Gear train By setting the head block to the down position, media is pushed against the “SA, Platen” by the “SA, Head”. As the “SA, Motor” (stepping motor) turns counterclockwise viewing from the right side of the printer, the “SA, Platen” turns counterclockwise via the gear train (“Gear PF1”, “Gear PF2” and “Gear, PF Idle”) and media is fed forward by the friction force produced between the “SA, Platen” and the “SA, Head”. When the “SA, Motor” turns clockwise, media is fed backwards. One step of the “SA, Motor” feeds media by 1/16 mm (0.0025").

2-1-3. Label/Tag Detection Mechanism The major components of the label/tag detection mechanism are: (a) Movable reflective sensor (Bottom sensor) (b) Movable transparent sensor (Upper sensor) There are two movable sensors, the reflective sensor (bottom sensor) and the transparent sensor (upper sensor). As shown in the figure blow, the reflective sensor has two LEDs and one phototransistor. The reflective sensor is used to detect black marks at the back of tag. On the other hand, the transparent sensor is a phototransistor that will receive the transparent light from the LEDs through the media. The transparent sensor is used to detect labels on liner or U-shaped notches of tag. Both reflective and transparent sensors are used to detect the media end. Aligning the sensors for label paper or tag with U-shaped notches: For label paper, both reflective and transparent sensors should be manually set at the center of label. For tags with U-shaped notches, both sensors should be manually aligned with the U-shaped notch. In both cases, the arrow mark of the transparent sensor should be aligned with the right side mark of the reflective sensor. Aligning the reflective sensor for tag with black marks: For tag with black marks, the reflective sensor alone should be aligned with the black mark. In this case, the left side mark should be aligned with the black mark.

Detecting labels: (Media Sensor menu: “See Through”) For detecting label, both reflective sensor and transparent sensor are used. Label paper passes between both sensors. The light emitted from the LEDs of the reflective sensor passes through the liner (base part of label paper) where no label is stuck on it, and the light reaches the transparent sensor. Accordingly, the phototransistor of the transparent sensor turns ON. Meanwhile, in the label part, the light is blocked by label and does not reach the phototransistor. So, the phototransistor turns OFF. By sensing the output of the transparent sensor, the CPU on the Main PCB can detect the label leading edge for printing. Detecting U-shaped notches of tag: (Media Sensor menu: “See Through”) For detecting U-shaped notches of tag, both reflective sensor and transparent sensor are used. The U-shaped notches are detected in the same way as the label mentioned above, except that the light is directly falls on the transparent sensor through the notch. Detecting black marks on tag: (Media Sensor menu: “Reflect”) For detecting black marks on tag, only the reflective sensor is used. Light emitted from the LEDs is reflected by the tag (at other than the black mark) and reaches the phototransistor of the reflective sensor. At the black mark, the light is not reflected. The CPU on the Main PCB detects the black mark by sensing the output of the reflective sensor.

Detecting continuous media: (Media Sensor menu: “None”) For detecting continuous media, only the reflective sensor is used. In this case, only media end is detected by the reflective sensor. LED light amount control: According to the media selected by the Media Sensor menu (“See Through”, “Reflect”, or “None”), the amount of light is well controlled to detect the label/U-shaped notch, black mark, or continuous media. The amount of light is as follows (the largest amount is for “See Through): • Continuous media (None) < Black mark (Reflect) < Label/U-shaped notch (See Through)


2-1-4. Printing and Ribbon Feed Mechanism The major components of the printing and ribbon feed mechanism are: (a) SA, Head (d) SA, Ribbon Tension Shaft F/R (b) SA, Ribbon Motor F/R (e) SA, Tension Sensor (Front/Rear) (c) Ribbon gear train Ink ribbon is set to the printer using the ribbon holders. Ribbon is supplied from the supply reel and is taken up by the take-up reel with adequate ribbon tension, via the “SA, Ribbon Tension Shaft F/R”. The “SA, Ribbon Tension Shaft F/R” is always pushed outward by the internal springs, and, when ribbon slacks, it moves outward. When ribbon tightens, it moves inward. (Refer to the figures on the later pages.) The same tension sensor is installed on the take-up and supply sides. The tension sensor on the take-up side is used to detect the position of the “SA, Ribbon Tension Shaft F”, i.e. the ribbon tension on the take-up side. While, the tension sensor on the supply side is used to detect the position of the “SA, Ribbon Tension Shaft R”, i.e. the ribbon tension on the supply side. The tension sensor on the take-up side is also used to detect a ribbon running condition, and that on the supply side is used to detect the ribbon end. On the take-up side, the Ribbon Motor F turns to take up ribbon. On the supply side, the Ribbon Motor R turns to supply ribbon, while applying adequate back tension to ribbon to eliminate ribbon slack. Printing: When printing with ink ribbon, ink on the ribbon is melted by the heated thermal element of the “SA, Head” and is transferred on the media surface. Taking up Ribbon: Ribbon will be taken up on the take-up side as follows: (1) As media is fed, ribbon is also fed by the friction force produced between media and the “SA,

Head”. (2) Ribbon slacks and the tension sensor on the take-up side turns OFF as the “SA, Ribbon

Tension Shaft F” is pushed outward. (3) The Ribbon Motor F starts to turn and ribbon is taken up. (4) Ribbon tightens and the tension sensor on the take-up side turns ON. Then, the Ribbon Motor

F stops. Supplying Ribbon: On the supply side, the Ribbon Motor R turns to supply ribbon, while applying adequate back tension. In the same way as on the take-up side, the tension sensor on the supply side detects the ribbon tension to keep the ribbon tension constant. However, when printing is made and ribbon is fed, the tension sensor on the supply side turns ON since ribbon is tightened at this time.

Reel Drive Mechanism: Though the ribbon holders are directly installed in the reels, ribbon is connected to the reels via the spring mechanism of the ribbon holders. This means that ribbon is taken up via the spring mechanism when the Ribbon Motor F/R turns. On the take-up side, the Ribbon Motor F turns in the clockwise direction viewing from the right side of the printer, the “Gear 5F, Ribbon” (take-up reel) turns in the counterclockwise direction via the Ribbon Gears 1, 2, 3 and 4, and ribbon is taken up. On the supply side, the rotational direction of the Ribbon Motor R differs depending on the ribbon winding type to be used. In the case of the outside-wound ribbon as shown in the following figure, the Ribbon Motor R turns in the counterclockwise direction, the “Gear 5R, Ribbon” (supply reel) turns in the clockwise direction via the “Gear 1, Ribbon”, “Gear 2, Ribbon”, “Gear 3, Ribbon” and “Gear 4, Ribbon”, and ribbon is supplied.

Detecting Ribbon Tension (Tension Sensors): The same tension sensor is installed on the take-up and supply sides. Since the operation is the same on both sides, the take-up side operation is explained here: When ribbon is taken up, it tightens and the “SA, Ribbon Tension Shaft F” is pushed inward (in the direction of “A”). At this time, the claw “C” of the “SA, Ribbon Tension Shaft F” is inserted into the photointerrupter of the “SA, Tension Sensor”, and the photointerrupter turns OFF. When printing starts, ribbon is fed forward together with media and it slacks. At this time, the “SA, Ribbon Tension Shaft F” is moved outward (in the direction of “B”) by the spring (“D”) force, and the claw “C” comes off the photointerrupter. So, the photointerrupter turns ON and the Ribbon Motor F starts to turn to take up ribbon. Then, the claw “C” is inserted into the photointerrupter again, and the Ribbon Motor F stops. This cycle is repeated and constant tension is applied to ribbon. On the supply side, when printing starts, ribbon is tightened contrary to the take-up side, and the tension sensor turns ON. Then, the Ribbon Motor R turns to supply ribbon.

Tension Adjustment Mechanism: To apply adequate ribbon tension, you can change the spring (“D”) force as follows: - Ribbon Tension Adjustment Knob F/R (for users)

Changes the spring force. The spring force is adjustable in 3 steps. As you move the knob toward the mark, the spring force becomes stronger .

- Tension Adjustment Screw (for service personnel) Can finely adjust the spring position. For details, refer to “3-6-3 Ribbon Tension Adjustment”.

2-1-5. Print Head Up/Down Detection Mechanism The component of the print head up/down detection mechanism is as follows: (a) Head up sensor (b) Protrusion that engages in the sensor The print head up/down detection mechanism detects the up (open)/down (close) status of the head block. When the head block is in the up position, the protrusion “A” is disengaged from the head up sensor. At this time, the head up sensor turns ON and “Low” level is output from the head up sensor. While, the head block is in the down position, the protrusion “A” is engaged in the head up sensor. At this time, the head up sensor turns OFF and “High” level is output from the head up sensor. The CPU on the Main PCB detects up or down position of the head block by sensing the output of the head up sensor.

2-1-6. Head Balance Adjustment Mechanism The major components of the head balance adjustment mechanism are: (a) Lever, Head Balance (c) Spring, Head L/R (b) Cam, Head Balance The head balance adjustment mechanism is used to eliminate uneven printing density on media. The head balance adjustment is accomplished by changing the right side head pressure according to media width to be used. To adjust, the blue Media width adjustment dial (“Cam, Head Balance”) is used. When narrow width media is used, the dial should be set toward “0” to give weaker pressure. When wide width media is used, it should be set toward “9” to give stronger pressure. When narrow media is used (need to give weak pressure): The “Spring, Head L” and “Spring, Head R” act to press the “SA, Head” against the “SA, Platen”. If the same pressure is given by both springs, since no media exists on the right side of the “SA, Head”, the “SA, Head” will slant to the right, resulting in uneven printing density. The part “A” of the “Lever, Head Balance” is pushed against the cam part by the “Spring, Head R” and it moves up step by step as the Media width adjustment dial is turned toward “0”. As it moves up, the “Spring, Head R” is pressed with weaker force by the “Lever, Head Balance”, and the right side pressure against the “SA, Head” is decreased, resulting in even printing density. You need to align the dial number according to the media width to be used. (Smaller number for narrower media) When wide media is used (need to give strong pressure): The same principle applies to wide media. However, in this case, the Media width adjustment dial should be turned toward “9”. Then the part “A” of the “Lever, Head Balance” moves down to apply stronger pressure to the “SA, Head”. (Larger number for wider media)

2-1-7. Media Offset Adjustment Mechanism The major components of the media thickness adjustment mechanism are: (a) Bracket, Head (b) SA, Head Adjust (Includes Head adjust lever and Media thickness adjustment dial.) According to the softness of media, the thermal element position is displaced from the optimum position. The head offset adjustment mechanism is used to correct this by moving the “SA, Head” back and forth a little. By performing the head adjustment properly, optimum printing quality is available. (When shipping, the Media thickness adjustment dial is set to “1”.) When soft media is used (thin thermal paper, label paper, etc.): When soft media is used, the optimum position of the thermal elements will be nearly right above the center of the “SA, Platen”. This position will be set when the Media thickness adjustment dial is set to “1”. When hard media is used (tag paper): When hard media is used, the optimum position of the thermal elements will shift toward the left a little from the center of the “SA, Platen”, viewing from the right side of the “SA, Platen”. As the optimum position varies according to the hardness of media, it is necessary to adjust the Media thickness adjustment dial from "1" to the greater number for the optimum position. As the Media thickness adjustment dial turns, the Head adjust lever also turns around the supporting point. At this time, as the end "A" of the “Bracket, Head” is inserted into the Head adjust lever, the “Bracket, Head” moves up and down. Note that the “Bracket, Head” turns around both “Bushing, Head” on both sides. When the Media thickness adjustment dial is set to the larger number, the end "A" of the Head Bracket lowers more. At this time, the thermal element position shifts to the left from the center of the “SA, Platen”, viewing from the right side of the “SA, Platen”.

(3) Sensors (3-1) Head up sensor

The head up sensor is used to detect the head position (up or down). This sensor uses a photointerrupter.) When the head block is closed (in the down position), the protrusion “A” of the head block is engaged in the head up sensor, and the light emitted from the LED of the photointerrupter is blocked by the protrusion “A”. Thus, the phototransistor turns OFF, and pin 117 (HDUSENS) of U1A (CPU) goes to "High" level. When the head block is opened (in the up position), the protrusion “A” is disengaged from the head up sensor, and the light emitted from the LED reaches the phototransistor. Thus, the phototransistor turns ON and pin 117 (HDUSENS) of U1A (CPU) goes to "Low" level.

(3-2) Transparent sensor and reflective sensor The transparent sensor is used to detect the label stuck on liner and the U-shaped notch on tag. On the other hand, the reflective sensor is used to detect the black mark printed on the bottom surface of tag. Both sensors are also used to detect the media end. The upper side transparent sensor is the phototransistor, and the lower side reflective sensor consists of 2 LEDs and 1 phototransistor. Media passes between these sensors. Transparent sensor (used for detecting the label or U-shaped notch): When the liner without label stuck on it passes between both sensors, the light emitted from the LEDs reaches the transparent sensor, passing through the liner. Thus, the transparent sensor (phototransistor) conducts and the voltage corresponding to the amount of light is applied to pin 5 (TRAMON) of U1A (CPU). Meanwhile, when the liner with the label stuck on it passes between both sensors, the light is blocked by the label and the transparent sensor (phototransistor) turns OFF. Thus, pin 5 (TRAMON) of U1A (CPU) goes "Low" level. From these levels, U1A (CPU) can detect the leading edge (arrival) of the label on liner. When media runs out, the light directly falls on the transparent sensor and media end is detected. In this case, pin 5 of U1A (CPU) will go "High" level. When the transparent sensor is conducted, the voltage at pin 5 (TRAMON) varies depending on the characteristics of the light receiving element (phototransistor) of the transparent sensor and other factors. To solve this problem, U11 (Custom IC) outputs TSNSCTL0 (pin 99) and TSNSCTL1 (pin 100) signals to turn ON/OFF (connect/disconnect) R71 and R72 (voltage dividing resistors) to minimize the difference in level at pin5 (TRAMON). The current flowing into the LEDs is determined by the data sent from the CPU to the digital-to-analog converter (U4). The digital-to-analog converter converts the data received from the CPU and outputs resoultant level at pin 2. The base current of the transistor Q7 is determined by this level. This means that the current flowing into the LEDs is also determined by this level. In the actual control, the CPU changes data (LED current) to keep the level at pin 5 of CPU constant.


2-23 CL-S621, CL-S621C & CL-S631

Reflective sensor (used for detecting the black mark on tag): When tag with black marks is used, light is reflected by the tag. In the place where no black mark is there, the phototransistor of the reflective sensor conducts and the voltage corresponding to the amount of light is applied to pin 6 (REFMON) of U1A (CPU). When the light falls on the black mark, no light is reflected. In this case, the lower phototransistor turns OFF and pin 6 of U1A (CPU) will go “Low” level. When media runs out, the light is not reflected and no light falls on the reflective sensor. In this case, pin 6 of CPU will go “Low” level and media end is detected. When the reflective sensor is conducted, the voltage at pin 6 (REFMON) varies depending on the characteristics of the light receiving element (phototransistor) of the reflective sensor and other factors. To solve this problem, U1A (CPU) outputs RSNSCTL0 (pin 176) and RSNSCTL1 (pin 175) signals to turn ON/OFF (connect/disconnect) R74 and R75 (voltage dividing resistors) to minimize the difference in level at pin6 (REFMON). As to the current control of the LEDs, the operation is the same as for the transparent sensor mentioned above.

(3-3) Tension Sensor F/R The Tension Sensor F is used to detect the ribbon tension on the take-up side (front side) as well as ribbon running. While, the Tension Sensor R is used to detect the ribbon tension on the supply side (rear side) as well as the ribbon end. These sensors are photointerrupters. Tension Sensor F: The Tension Sensor F is used to keep the ribbon tension on the take-up side constant. When printing starts, ribbon is fed and take-up side ribbon slacks. Then, the claw of the “SA, Ribbon Tension Shaft F” comes off the photointerrupter on the Tension Sensor PCB and the photointerrupter turns ON. Thus, pin 97 (SENS_A) of U11 (Custom IC) goes "High" level. Then, U1A (CPU) drives the Ribbon Motor F to take up ribbon. As a result, ribbon tightens and the claw is inserted into the photointerrupter. Thus, pin 97 (SENS_A) of U11 (Custom IC) goes "Low" level. Then, U1A (CPU) stops the Ribbon Motor F. During printing, this cycle is repeated and constant ribbon tension is maintained. The LED (D901) on the tension sensor lights when ribbon slacks (the claw of the “SA, Ribbon Tension Shaft F” comes off the photointerrupter and the photointerrupter turns ON). The LED goes out when ribbon tightens. If ribbon is not correctly fed during printing, the ON/OFF state of the photointerrupter on the Tension Sensor F becomes improper. Thus, the CPU can detect a ribbon running error. Tension Sensor R: The Tension Sensor R is used to keep the ribbon tension on the supply side constant. When printing starts, ribbon is fed and supply side ribbon tightens. Then, the claw of the “SA, Ribbon Tension Shaft R” is inserted into the photointerrupter on the Tension Sensor PCB and the photointerrupter turns OFF. Thus, pin 98 (SENS_B) of U11 (Custom IC) goes "Low" level. Then, U1A (CPU) drives the Ribbon Motor R to supply ribbon. As a result, ribbon slacks and the claw comes off the photointerrupter. Thus, pin 98 (SENS_B) of U11 (Custom IC) goes "High" level. Then, U1A (CPU) stops the Ribbon Motor R. During printing, this cycle is repeated and constant ribbon tension is maintained. In the same way as for Tension Sensor F, the LED (D901) on the tension sensor lights when ribbon slacks and goes out when ribbon tightens. When ribbon runs out, the ON/OFF state of the photointerrupter on the Tension Sensor R becomes unchangeable. Thus, the CPU can detect the ribbon end.

(3-4) Head temperature sensor The head temperature sensor is used to detect the temperature of the thermal head. This sensor is a thermistor incorporated in the “SA, Head”. Since the resistance of the thermistor changes according to the temperature change, the voltage at pin 7 of U1A (CPU) changes accordingly. The CPU senses the voltage at pin 7 to detect the head temperature. According to the temperature of the print head, the CPU controls the printing pulse width applied to the thermal elements to keep the printing density constant. Printing operation when the head temperature rises: If the head temperature reaches 70°C (158°F), printing stops after printing the current label.

(4) Drivers (4-1) PF motor driver

This is a driving circuit to drive the PF motor (stepping motor). The following illustration shows a simplified circuit. The PF motor is driven by the bipolar constant current chopper method. The exciting method for the motor is the 1st-2nd phase method. The power to the PF motor is supplied by turning ON the FET Q5. This is accomplished by activating the monostable multivibrator U14A. When U14A is triggered, Q6 turns ON and Q5 turns ON. The exciting method is determined by PFMS1 and PFMS2 signals sent from U11 (Custom IC). The rotational direction of the PF motor is determined by PFDIR signal and the PF motor rotates when a pulse (PFCLK) is input to STEP (pin 14 of U15). The digital-to-analog converter (U4) is used to control the PF motor current. Its output is controlled by the data sent from the CPU (U1A). PF motor forcible stop function by circuitry: The CPU monitors the temperature of the PF motor and stops the PF motor if its temperature reaches 105°C (221°F), as mentioned in “(3-4) Motor temperature sensor”. In addition to this function, for further safety measures, a circuitry is provided to forcibly stop the PF motor if its temperature exceeds over 105°C (221°F). When the temperature reaches to a predetermined level, ENABLE (pin 2) of U15 becomes “Low” level and the outputs from U15 are disabled.

(4-2) Ribbon motor driver This is a driving circuit to drive the Ribbon Motor F and Ribbon Motor R (stepping motors). The Ribbon Motor F is used to take up ribbon and the Ribbon Motor R is used to supply ribbon. The Ribbon Motor F/R is driven by the STEP_A/B signal sent from the CPU (U1A). The rotational direction of the motor is determined by the DIR_A/B signal sent from the custom IC (U11). The strength of PF motor excitation (strong and weak) is switched by the PDOWN signal sent from the CPU (U1A). The motor drive circuits for the Ribbon Motor F and Ribbon Motor R are the same. Ribbon motor forcible stop function by circuitry: The CPU monitors the temperature of the Ribbon Motor F and stops it if its temperature reaches a certain level, as mentioned in “(3-6) Ribbon motor temperature sensor”. In addition to this function, for further safety measures, a circuitry is provided to forcibly stop the ribbon motors if the temperature exceeds over 105°C (221°F). When the temperature reaches to a predetermined level, RBTMP (pin 7) of U16B becomes “Low” level and the supply power to the ribbon motors is shut down.

(4-3) Head driver The head driver is incorporated in the “SA, Head”. During printing, pin 116 (HDVON) of U11 (Custom IC) goes to "High" level, and Q2 and Q1 turn ON. Thus +24V is supplied to the thermal head (“SA, Head”). The print data is sent from the Custom IC (U11) to the head driver to select the thermal elements to be heated. The data is sent via HDATA1-HDATA3, HDSTB, HDCLK and HDLTH lines (pins 113, 111, 110, 108, 115 and 107 of U11). According to the print data received, the thermal head heats the thermal elements to print dots on thermal transfer paper. The width of heating pulse will be changed according to the head temperature to keep the printing density constant.

Thermal resistance check: When the printer is turned ON, the thermal resistance check is conducted. If any fault is found, it is memorized and, when the printer is turned ON next time, the CONDITION LED and ERROR LED alternately blink on the operation panel. During the thermal resistance check, pin 117 (HCVON) of U11 (Custom IC) goes to "High" level, and Q4 and Q3 turn ON. Thus, +5V is supplied to the thermal head, instead of +24V. The following is a simplified circuitry under checking, where Q3 turns ON and a thermal element "R" is selected. At the point "A", the voltage divided by R38 and R is developed. The CPU monitors this voltage at pin 10 (HEADRES), and check if the voltage is out of the allowable range or not. (For example, if R is open, the voltage at point “A” will be about +3.3V.) Each thermal element is successively checked in this way.

(3-1) General

Factory mode and Service mode are available for maintenance. Factory mode: You can change the factory-set items such as logical shift of the sensor or head, and double heat (printing the same dot twice). Note: • In Factory mode, DO NOT change the factory-set values unless you need it, since

there are essential items related to printing accuracy, etc. Service mode: You can perform checks such as “head check “and “counter print” to print the total print length since the printer is firstly used.

It is an asynchronous forward channel mode to send the byte width data from the host to the printer. The interface line of the data is operated in accordance with signal line definitions of Centronics. NIBBLE mode It is an asynchronous reverse channel mode to send the data from the printer to the host. In Nibble mode, 4-bit data (half byte) is sent at a time using the 4 status lines (FAULT, SELECT, PE, and BUSY). To send one complete byte data, the printer sends 2 nibbles (8 bits in total) to the host. Nibble mode is usually combined with Compatible mode to create a complete bi-directional channel. ECP mode ECP mode permits bi-directional asynchronous data transmission, and by means of interlock handshake, it does not require the timing necessary with Compatible mode.

2-5-2. Block A (Noise filter circuit and rush current preventing circuit) The filter circuit consists of the power switch (SW1) the fuse (F1), the X capacitors (C1, C2), the Y capacitors (C3, C4), the common mode choke coils (L1 and L2), the varistor (Z1), and the thermistor (R1). This circuit eliminates switching noise from the power supply to the main power line. Also, it eliminates noise from the main power line to the power supply to protect the power supply circuit. The thermistor R1 suppresses the rush current to the power supply circuit at power on. In continuous operation, the resistance of R1 is reduced as it is heated, reducing the power loss by R1. 2-5-3. Block B (Current smoothing circuit) This block consists of the bridge rectifier DS1, the smoothing capacitors C5-1 and C5-2, and resistors R8 and R10. <For 120V type> Half-wave rectification is performed by the bridge rectifier DS1 and the capacitor C5-1 and also by the bridge rectifier DS1 and the capacitor C5-2. Thus, the DC voltage across R8 and R10 (output of this circuit) becomes approx. 2.8-time of the AC input voltage. (It will be approx. 320V DC if the input voltage is 115V AC.) This DC voltage is supplied to the next converter and driver circuit. The choke coil L3 suppresses high frequency waves to meet the regulations against high frequency waves.

<For 200-240V type> Full-wave rectification is performed by the bridge rectifier DS1 and the capacitors C5-1 and C5-2. The DC output of this circuit will be approx. 1.4-time of the AC input voltage. (It will be approx. 320V DC if the input voltage is 230V AC.) This DC voltage is supplied to the next converter and driver circuit. The choke coil L3 suppresses high frequency waves to meet the regulations against high frequency waves. 2-5-4. Block C (Converter and driver circuit) (1) Converter circuit

The converter circuit operates with conducting-angle-controlled reverse method with frequency fixed. The rectified and smoothed voltage (e.g. 320V DC) is converted by the switching transformer T1 and then supplied to the secondary circuit. When Q1 is turned ON, 320V DC is applied to the primary winding N1 of T1. At this time, the voltage is induced in the secondary windings N3 and N4 and energy is charged in T1 since the energy flow to the secondary output circuit is blocked by the diodes DS2 and DS3. When Q1 is turned OFF, the energy polarity is reversed and the energy charged in the secondary windings N3 and N4 is discharged to the secondary output circuit through DS2 and DS3. Above operation is repeated and the energy is continuously fed to the secondary output circuit.

2-5. Power Supply

2-61 CL-S621, CL-S621C & CL-S631

The following circuit reduces the switching noise. So the output noise and the EMI (electromagnetic interference) noise are suppressed, and the reversal voltage applied to Q1, DS2 and DS3 is also reduced. • C13 and R25 connected between drain and source of Q1 / D1, C6, R7 and R5 connected to the primary winding N1 / C18, C21, R28, FB2 connected to DS3 / C29, C30, R26, FB1 connected to DS2

(2) Driver circuit The switching FET (Q1) is driven by the control IC (IC1). When power is turned ON, power is applied to pin 6 (VCC) of IC1 through R3 and R4. Then, the current starts to flow into the primary winding N2 and voltage is produced there. When the voltage at pin 6 (VCC) reaches approx. 16V DC, IC1 is activated and a pulse is output from pin 5 (OUT) of IC1 to drive Q1. When Q1 starts switching, approx. 20-25V DC is supplied from N2 to pin 6 (VCC) of IC1 to stably activate IC1. During stable oscillation, the switching pulse is continuously output from pin 5 (OUT) of IC1 to Q1 through R17, R18 and D3. The oscillation frequency is determined by R12 connected to pin 1 (RT), and the conduction-angle control is made by the control voltage fed from the secondary circuit to pin 2 (FB) of IC1. The following timing chart shows the control waveforms at various points.

2-5-5. Block D (Output circuit) DS2, C15 and C16 perform half-wave rectification to produce +24V. DS3 and C19 perform half-wave rectification to produce DC voltage to supply to the +5V regulator IC (IC31). IC31 produces a stabilized +5V voltage. 2-5-6. Block E (Control circuit) The shunt regulator (IC32) and photo coupler (PI1) detect the output voltages (+24V and +5V) and feed the signal back to the primary side. R33, R34, R36 and VR1 are used to detect +24V and +5V outputs. The voltage produced by these resistors is compared with the reference voltage of IC32 (2.5V). If there is a difference between both voltages, the current flowing into the photo coupler PI1 is changed. So, the signal fed back to pin 2 (FB) of IC1 in the primary side is also changed. Then, the conduction-angle for Q1 is changed to stabilize +24V and +5V constant. <Over current protection circuit> The over current protection circuit detects the drain current of Q1 to check if power supply circuit is overloaded or its output is short-circuited. If over current is detected, IC1 cuts off the output signal from pin 5 (OUT) for protecting power supply circuit. The drain current (Id) of Q1 is detected by R23, R22, R21 and C11, and input to pin 3 (IS) of IC1. If the voltage at pin 3 (IS) exceeds the internal reference voltage (0.24V) of IC1, the switching pulse sent from pin 5 (OUT) is cut off, resulting in lower output voltage. If over current condition due to overloading or output short-circuit continuous, the voltage at pin 8 (CS) of IC1 increases, and after a certain period of time, the voltage will exceed the internal reference voltage (8.5V) of IC1. In this case, IC1 is latched to off mode and the output at pin 5 (OUT) is set to “Low” level (off condition). Then, the output voltages (+24V and +5V) is shut off. To recover the latched state, turn OFF the power and, after a while, turn it ON again. <Protection circuits in case of abnormality> In case of abnormality, the power supply circuit automatically stops its operation to avoid smoking or fire. When temperature of the power supply raises abnormally, the thermal fuse TF1 opens and the drive signal to Q1 is cut off. When the output voltage rises, the voltage across the primary winding N2 also proportionally raises. In this case, the Zener diode ZD1 is turned ON and the voltage higher than 8.5V is applied to pin 8 (CS) of IC1. Then, IC1 enters latch mode and stops its operation. To recover the latched state, turn OFF the power and, after a while, turn it ON again. If large current flows, the fuse (F1) in the noise filter circuit will be blown out.

Principle of operation of parallelism change with the “Cam, Tension Base Adjust”: The parallelism of the “Unit, Ribbon Sensor F/R” can be changed by means of the eccentric mechanism of the “Cam, Tension Base Adjust”. The “Cam, Tension Base Adjust” has projections “a” and “b”. The projection “a” is inserted into the slotted hole “a’ “ on the base (fixed part), while the projection “b” is inserted into the hole “b’ “ on the “SA, Ribbon Tension Frame F/R” of the “Unit, Ribbon Sensor F/R” (movable part). As you can see from the figure, the projection “a” is eccentric with respect to the projection “b”. Accordingly, as your turn the “Cam, Tension Base Adjust” (after loosening screws “A” (2 pcs.) and “B”), the eccentric projection “a” pushes the slotted hole “a’ “ so that the “Unit, Ribbon Sensor F/R” itself turns around the supporting point “c”. (The “Unit, Ribbon Sensor F/R” turns in the same direction as you turn the “Cam, Tension Base Adjust”.)

Removing Ribbon Wrinkles

T

he following explains the general procedure for removing ribbon wrinkles.

Adjusting points: • Ribbon tension • Ribbon Left-Right Balance Adjustment Knob (Front) - Ribbon slant • Ribbon Left-Right Balance Adjustment Knob (Rear) - Ribbon slant • Ribbon Guide Shaft (a part of the “SA, Head”) - Ribbon slant How to check ribbon wrinkles: • Visual check Adjustment procedure: First, adjust the ribbon tension and then the ribbon paths (front/rear) to remove ribbon wrinkles. (1) Ribbon Tension Adjustment

1. Adjust the ribbon tension on the front and rear sides to obtain the specified value. Refer to “3-6-3 Ribbon Tension Adjustment”.

2. Proceed to the next item, (2). (2) Ribbon slant elimination adjustment

Ribbon is fed from the supply side and taken up on the take-up side via the “SA, Ribbon Tension Shaft R” of the “Unit, Ribbon Sensor R” and the “SA, Ribbon Tension Shaft F” of the “Unit, Ribbon Sensor F”. (See the figure on the next page.) 1. Adjust the Ribbon Left-Right Balance Adjustment Knob (Front) and then the Ribbon

Left-Right Balance Adjustment Knob (Rear) to remove ribbon wrinkle. Refer to “3-6-2-(1) Ribbon slant elimination adjustment (For user)”.

2. If satisfactory results are not obtained, the following adjustments will be required. • “3-6-2-(2-1) Tension base adjust cam position adjustment (For service personnel)”.

• “3-6-2-(2-2) Ribbon guide position adjustment in the “SA, Head” (For service personnel)”. (2-1) Visual check and adjustment

Checking the ribbon surface visually is a good way to see whether the ribbon wrinkles or not. You can find wrinkles by the reflected light on the ribbon surface. Check both take-up side and supply sides of ribbon. (See the figure on the next page to find the places where wrinkles may appear.) Note: For removing wrinkles, front side adjustment is more effective than the rear side

one.

1. Perform test print in self print mode. (Refer to “2-3-2-(2-1) Self print mode”.) 2. Visually check the take-up side for ribbon wrinkles.

Since ribbon is taken up stronger on the shorter ribbon path side, wrinkles appear on the longer path side. During printing the self print patterns, check wrinkles and correct the ribbon travel as follows: • If wrinkles are found on the left side (“a” in the figure), turn the Ribbon Left-Right

Balance Adjustment Knob (Front) clockwise. • If wrinkles are found on the right side (“a’ “ in the figure), turn the knob

counterclockwise.

3-6. Adjustments

CL-S621, CL-S621C & CL-S631 3-52

• If wrinkles are found at around center, find the side (either front or rear) and turn the knob accordingly.

3. Visually check on the supply side for ribbon wrinkles. Since ribbon is pulled stronger on the shorter ribbon path side, wrinkles appear on the longer path side. During printing the self print patterns, check wrinkles and correct ribbon travel as follow: • If wrinkles are found on the left side (“b” in the figure), turn the Ribbon Left-Right

Balance Adjustment Knob (Rear) counterclockwise. • If wrinkles are found on the right side (“b’ “ in the figure), turn the knob clockwise. • If wrinkles are found at around center, find the side (either front or rear) and turn the

knob accordingly. 4. Be sure that the adjusted positions in Steps 2 and 3 are at around the center of scales,

respectively. Note 1: If they are off-center widely or wrinkles cannot be removed, the “Cam,

Tension Base Adjust” position may be wrong. Perform “3-6-2-(2-1) Tension base adjust cam position adjustment (For service personnel)”.

Note 2: To remove ribbon wrinkles on the front side, the ribbon guide position is adjustable. Refer to “3-6-2-(2-2) Ribbon guide position adjustment in the “SA, Head” (For service personnel)”.
