9. Trouble Shooting

Check Points

After a machine has been assembled properly, please follow the instructions below.

1. Load a piece of paper instead of vinyl film nice smoothly.

2. Load a ball pen in the front holder position instead of a blade in the rear holder position.

3. Move press feeding wheels properly by hand and make sure not places them on the joints of rolling

shafts).

4. Adjust the springs of press feed wheels nice evenly.

5. Connect the power cable and switch the power on. The carriage head will move to the right end of

the machine.

6. Check the LCD screen of the machine, the baud rate must be 9600. The Up‐speed on LCD screen

means the idle speed of carriage when it’s not in cutting, e.g. the speed to return to starting point

once finish cutting, the speed of moving the carriage to right or left by pressing arrow buttons.

7. Trial drawing/cutting Machine hardware check (offline mode, not connect to a PC)

Action: Power on + Reset on (1st button, red LED) + Test (4th button, no LED light). Response: The machine should draw (ball pen and paper loaded) trail pattern.

8. If the trial drawing/cutting is not OK, then need to check X, Y, Z axis separately.

Z axis check Action: Reset on (1st button, red LED) + Original (fifth button). Response: the carriage head should lower and upper correspondingly.

X axis check Action: Reset on (1st button, red LED) + Online/Offline (2nd button, Yellow LED) + F+/F- arrow buttons. Response: The carriage head should move left or right correspondingly.

Y axis check Action: Reset on (1st button, red LED) + Online/Offline (2nd button, Yellow LED) + V+/V- arrow buttons. Response: The rolling shafts should roll forward or backward correspondingly.

9. If the trail drawing/cutting is OK the machine is generally considered as good. Then starts focus

on Software settings of USB driver and Artcut installation. Refer to section 7 of this manual for detail.

9.1. Carriage Assembly The knife holder is sluggish to rise: Check the copper connection plates under the dolly cover to ensure they are well

connected. This may require the use of a soldering iron to correct. The Z axis drive (knife up and down): The drive solenoid winding is burnt out or the connection wire between dolly and main

PCB is broken. The knife holder can be raised but not lowered: The magnetic Z drive cylinder is touching the windings, There is a large friction

somewhere impeding movement or the –12V from the power supply is missing. The dolly is jerky when moving or even falls from the guide rail: The nylon guide rollers on the dolly are damaged or badly

worn or the toothed drive belt is loose or damaged. The dolly won’t move at all or will only move in one direction: a stepper motor is faulty or its driver IC on main board is faulty. The dolly moves to one side and slams into the metal plate: The limit sensor or limit sensor PCB is faulty or the limit sensor

HIGHLIG

Page 24/27

infra-red beam is not being correctly broken by the interrupter arm fitted to the dolly: Adjust arm or replace faulty parts as required.

9.2. Paper Pressure & Feeding Shaft Motors make noise but the paper is not driven correctly or at all: There is too much pressure between the pinch rollers and the

metal drive roller shaft – use one less pressure roller. Paper runs off to one side while cutting: Incorrect paper installation or the pressure of the pinch rollers is uneven, try using one

pinch roller on the left and two close together on the right side. The pressure pinch roller assembly’s do not slide well on the rail: Apply a tiny drop of lubricating oil to the shaft and wipe off

any excess oil as it will attract dust and make the problem worse. DO NOT spray pressure pack oil such as WD40© or similar on the machine at any time.

The pinch roller pressure is not enough to hold the paper firmly: Adjust the pressure as required or the rubber pinch rollers are worn and require replacement.

The metal drive roller doesn’t move (Y axis): The stepper motor is faulty or the driver IC 3955 is faulty.

9.3. Power Supply Power cuts on and off when using the machine: The power supply lead is faulty or the power socket on the machine is

damaged. Power won’t turn on at all: Check the fuse or the power supply is damaged.

9.4. Random Cutting and Unpredictable Connecting serial cable is damaged. COM port of computer is faulty. Main PCB of machine is damaged. The machine has not reset correctly (press manual reset). The paper settings in software don’t match the available material. The machine may be affected by static electricity, ensure correct earth. Ensure all software settings are correct (this is most likely to be the problem).

9.5. Not Output any work (No Response) Port settings in software are incorrect (check these settings first). COM port on computer is damaged. Machine selection in software is incorrect. Connecting serial cable is faulty. Main PCB is faulty.

9.6. Produced Work has Jagged Edges

Insufficient knife pressure. Check software settings (settings of compensation parameter, closing parameter and accuracy in cutting output parameter will

all affect this). The internal bearings of the knife holder may be jamming or damaged, check that the blade can spin freely in the holder

(CAUTION – sharp blade). Fonts in the font database do not match with the drawing sent to the cutter. Cutting Inaccuracies There are gaps in the produced work: The white blade pressure strip is damaged or worn or the knife blade cannot rotate in

the holder freely. The cut depth is different on the left and right sides of the machine: The metal roller is not square to the machine, perform a

adjustment. The machine only cuts a length of, say, two metres when three have been sent to the machine for cutting: Output setting in

Artcut© (output length limitation in compensation setting) is limiting the length of material the machine can cut. The depth of cut varies across the work at random: Possible static electricity interference, ensure machine is correctly earthed

to PC.

10. FAQ Q1: Will the characters below 1CM be deformed?

When graving small characters, please set sharp-angle compensation in the software. For example, in Wentai plotting software. Steps: File → Cut/Plot… → Setup Plotter Compensation → Sharp angle 0.25

* The compensation ranges within 0.1-0.7, more often we set it to be 0.25 mm. In addition, the plotting speed of the cutter shall be set below 20.

Q2: Why there is an additional stroke after finishing cutting

1. Check if the tip of cutter is flexible when it is up and down. 2. Check if there are some problems on the files you are working on.

Q3: Why zigzag happen to the cutter?

As cutter motor features high power and speed, so the cutting speed shall be adjusted according to size of character. Generally, to cut small glossy characters with high requirement for precision, the speed shall not exceed 40. In most cases, the speed at the shaft 50 ~ 60 is favorable. To cut big characters of large quantity within shortest time, the speed can be 70 ~180, but since step distance of motor is so long that evident zigzag occur. Therefore, you should set the speed to specific size of characters, and the relationship between speed and size of characters please refer to following table:

Size of font（mm） Speed

＜10 10-20

10-30 30

30-50 40-50

50-500 60

＞500 70-80 Q4: Why the paper deviate when it runs by a large margin?

The paper feed bracket containing paper roll shall be completely parallel to paperweight wheel, for big roll of materials, loosen it prior graving to prevent excessive obstruction when plotting or graving. For the machines with four paperweight wheels, when plotting big image or characters back and forth, use the two paperweight wheels at sides instead of press the four down simultaneously. Unequal abrasion of the two wheels also may result in deviation of the paper; in worse case replacing wheels is needed.

Q5: Why the machine feel tingle?

The machine might be improperly grounded, make sure central line of the power source grounded。 Q6: Why the job feel not smooth with sharp-angle raised when plotting?

1. The protruding length of knife top is too long, please adjust it as required. 2. The knife is worn, replace it.

Q7: Why the plotter cuts or draws a line before plotting?

Because the machine improperly exited from previous operation, there is still knife-dropping instruction existing in the memory of plotter. To resolve it, power off the machine and turn it on again.

Q8: Why no or black rows displayed on LCD panel?

1. In case of no display, check whether the power work well. 2. If black blocks are displayed, check whether voltage is at required level. If the troubles remain after the above operation, please contact maintenance center.

Q9: Why some characters can’t close in strokes when it is plotting?

Because the knife of the plotter is eccentric knife with a eccentric value, to resolve it, set“closing compensation”in the software. For example, With Artcut software: 1. Click“plotting output”once, a plotting output picture will pop up. 2. Click“set”once, a picture of setting plotter will pop up. 3. Click“compensation setting” a dialog box will pop up. 4. Select closing compensation, adjust the value to required level, generally the value is set to be 0.5.

Q10: Why the plotter has missed some pave of letter when cutting?

1. Check the machine if it presses enough. 2. Reinstall the software. 3. Chook the head of the knife. 4. If the problem is still existence, please contact with repair center.

Q11: Why the plotter starts low-speed after start-up?

Because paper sensor fails to detect the fore end of paper. When feeding paper make fore end of paper cover hole of paper sensor, and then perform another automatic paper testing.

Q12: Why some nicks deep and other shallow when cutting?

The cutter employs upscale soft PVC materials as knife strip cushion to protect knife. But after using for long period, it may produce some tracks therefore roughing the stripe cushion, so some nicks become deep, while some become shallow. To resolve it replace a stripe cushion. If is not so worse, adjust knife pressure (some 120 -150).

Q13: Why the plotter has no response when it is outputting?

1. Check the properties of COM port, baud rate, flow control, parity check and data bits both on PC (device manager) and Software (Artcut).

2. Check all cables, plugs, fuse and power. 3. PC or Software may affected by virus, remove or reinstall.

Q14: Why an instant-glue paper can’t be peeled off?

1. Perform trial run prior output, adjust press to appropriate level. 2. Check whether the knife worn too much, or whether the knife tip is broken. For new ones the nick is thin in the instant-glue, while

for old ones the nick is thick and impressive. To resolve it replace it with a new knife.

Q15: What steps need to be taken when cutting big characters?

1. When cutting big characters, the system can automatically setup pages, you can cut a big character in several pages, but it is notable that the setting of output width shall be conformed to the width of instant-glue in addition, when cutting big characters and output it, you should widen pages or set seaming distance.

2. When you use the special wide machine to cut the big characters, especially the long big characters before cutting input, you shall instead the paper first look careful the paper if the paper deviates then deviate the big characters into some pouts to input, it can make sure it won’t deviate and waste paper.

Q16: How to maintain the machine?

The machine employs high grade bearing oil, no extra oil needed even it works for a long time. After operation everyday, clean the dust with soft brush. The glue remaining in engine base can be cleaned with alcohol. If frequently operated in dusty environment above two years, please have maintenance technicians clean the dust in machine. If plotting precision degrades, the maintenance of running parts are desirable (firming and replacing the abraded parts).

Q17: Why the plotter is out of control sometimes?

Check all cables, open the machine properly.

Q18: Why the plotter comes to halt?

Because it encounters vibration for a long period, or has been used for a long period, or is affected by temperature, so dielectric displacement happen to the servo driving board, therefore resulting in halt, please contact local agent or customer maintenance center.

Q19: Why the pattern has been deformed or incomplete?

1. Too high pressure or too long blade tip or too dirty platen or too soft stickiness, all of these factors can cause more resistance to the two faces of paper and make it fall behind the roller rotating, thus result in deformed pattern.

2. The software setting isn’t proper. (The tool compensation value is too big) 3. The carriage belt is too loose, or the metal roller can’t exactly follow the motor running. 4. The motor doesn’t run all the steps. 5. The pattern is normal but not completed. It may be resulted from too small tool compensation value.

Q20: Why does the paper run deviation?

1. The stickiness isn’t placed right. 2. The platen is too dirty so that the resistance from two sides can’t be balanced when the paper is moving. 3. The pinch rollers have been deformed or don’t match to each other. 4. The pressure of the feeding press wheel is a little smaller and the paper is very sensitive to the external force. 5. The balance of the stickiness weight isn’t very good.

Q21: Why some parts of letters missing?

1. The vinyl is too heavy or too tightly wrapped. Metal roller might be soiled by some foreign substance or by vinyl chips. 2. Cutting speed is too fast, cutting force is too great, or cutter tip is too long. 3. Synchromesh belt is too tight, or pinch roller is under too much pressure. 4. Metal roller is faulty. Contact local distributor for repairs and replacement.

Q22: Why different letters on the same line are cut to different depths?

1. Cutter holder is not tightly attached. It should be tightened. 2. Cutter blade is not tightly set in the holder.

Q23: Why letters appear to have ripples?

1. Cutting speed is too fast. Except for cutting large letters, speed should not exceed 480mm/s. 2. Cutting blade is of poor quality, or it has been damaged. Replace it. 3. Cutter holder is not tightly installed. Tighten screw.

Q24: Cutting small letters

When cutting small letters, cutting speed and force should be adjusted to the lowest setting. Similarly cutter tip should be adjusted to as short as possible.

Q25: Cutting large letters

Cutting speed and force may be increased to higher settings. When cutting large letters Sharp Angle in Artcut software may be ignored.

The plotting cutter is made in China HIG
