SIQA USER GUIDE

J75 – C75 SIQA Auto Density Uniformity instructions

version 2.1 December 14

■Introduction

This document explains the Smile Correction (Density uniformity) operation using the new application, so-called

SIQA, Simple Image Quality Adjustment.

Conventionally, for example on 700 family printers and other products, we have to spend long time to correct the

Inboard to Outboard Image Quality issues.

SIQA makes this complicated operation to an easy one, completed in approx. 5 minutes.

■Environment - Prerequisites

- Printer

- Client PC with SIQA application installed. (OS: Windows)

2

Pre-Adjustment steps • Record the IP address to be use later on the SIQA tool. There are different ways to find this IP address

depending of the DFE used on your printer.

o For user with FFPS DFE Server, the IP address can be found on the Printer UI panel. Access

Machine status and record the IPv4 address.

o For user with EFI DFE standalone server, the IP address needed is the EFI IP address and can be

found on the configuration sheet OR by accessing the Device Center in the General folder inside

the Command Workstation.

o For user with EFI Integrated server, the IP address needed is the EFI server and can be found by

printing the configuration sheet – powering on and off the IOT will force the EFI Integrated to submit

that configuration sheet.

AT THE PRINTER ◆ Operation on Parma/Prosecco

• Select “Login/Logout” button on the UI panel

• Log-in as a System Administrator by typing “admin” as ID (password).

• Select “Machine Status” folder on the UI panel screen

• Enter Tools mode. On the Feature column Scroll to the next page and Select Maintenance

.

• On the Maintenance screen, Scroll down

DENSITY UNIFORMITY (Smile Correction) ADJUSTMENT • Select “Density Uniformity Adjustment”

• Select “Semi-Auto Process” using Scanner Adjustment for Smile correction .

• UI screen to set the detail conditions.

o Select the target tray for the adjustment.

• After selecting “Print”, the printer will produce 2 test patterns; one in CMYK and one in RGB mode.

• To start the adjustment process, scan one test print at a time. (See the Printer UI for correct scan).

5

• First scan should use the CMYK pattern – MATCH the print picture from the UI

Cover each test print with 4-5 blank sheets to avoid “see through” effect.

• Press: “Start”

• Scan the second test print (RGB) - MATCH the print picture from the UI

• Press: “Start”

• Select ”Confirm” to send the data to the Printer folder.

INFO: The scanned data are saved into the Mail Box on the Parma/Prosecco DMP controller.

The saved data will be read and analyzed later by the 3rd

Party PC..

AT THE 3rd PARTY PC ◆Operation on Client PC

• Start up the application by clicking SIQA shortcut on the desktop and log in as a key operator. You may have

to enter/confirm the IP Address of the Printer recorded earlier. Start up the application by clicking the SIQA

shortcut on the desktop and log in as the key operator.

If the tool fails to open – see the “Troubleshooting section”

• Select “Density Uniformity Adjustment” from the SIQA pull-down menu. Press “Start”.

• You may have to enter/confirm the IP address of the Printer recorded earlier. NOTE: If the SIQA tool is

communicating to a printer using FFPS DFE – enter the IP address found on the IOT screen.

• Select “Start” button. Then the scanned image data in the Mail Box will be read in.

The image data will be analyzed and automatically the adjustment values will be calculated. Few screens will shows

on the screen – be patient.

7

• After a few minutes, a new screen will appear and display “Correction Result” showing the possible

improvement to correct Inboard to Outboard density variation.

Another screen is available if you press “Details” (Correction Parameters).

• Select “Close” on both screens.

• If you want to apply the above adjustments, select “YES”, then the values will be written onto Printer NVM.

At this point, the IOT will cycle up and down 4 to 8 times to allow each ROS to initialize to the new values.

• Printer will go automatically in Diagnostics to accept the new NVM’s values.

8

• Adjustment is completed. Press “OK” to close the screen.

• Adjustment can be verified by running the same pattern in earlier steps

TROUBLESHOOTING SECTION

• If the Test Prints are “see through” – incorrect readings may occurs – ADD blank sheets to ensure the

scanner is recording correctly.

• If the following message occurs while writing parameters to the printer. This is a known Controller bug with

sw .223 and ,224. Press the “Clear All” twice on the PCUI to re-establish the connectionion between the

UI and the 3rd

party PC . A “Confirm” button needs to be press to allow communication once again. Press

“Yes” to complete.

• If the left screen appears at the 3rd party PC during the analysis, ensure that you are scanning

the CMYK/RGB test prints with the top black bar on TOP - flat and square (NOT skewed)

againt the DADF registration edge. The 2nd screen reminds you to perform the routine once

again.

• If the left screen appears at the 3rd party PC during the analysis, ensure that you are scanning

the CMYK/RGB test prints with the black bar on top againt the DADF registration edge. The

2nd screen reminds you to perform the routine once again.
