1. LIST OF ERROR DISPLAY
Errors and warnings are displayed by the following ways:
- Operator call errors are indicated by the Alarm LED lit in orange, and the error and its solution
are displayed on the LCD in text and by icon.
- Messages during printing from a computer are displayed on the MP driver Status Monitor.
- Error codes (the latest 10 error codes at the maximum) are printed in the "operator call/service
call error record" area in EEPROM information print.
Buttons valid when an operator call error occurs:
- ON button: To turn the machine off and on again.
- OK button: To clear and recover from an error. In some operator call errors, the error will
automatically be cleared when the cause of the error is eliminated, and pressing
the OK button may not be necessary.
- Stop button: To cancel the job at error occurrence, and to clear the error.

< LF / Eject correction >
After replacement of the feed roller, platen unit, LF / Eject encoder, encoder film, or logic board in
repair servicing or in refurbishment operation, perform the adjustment to maintain the optimal print
image quality.
1) Print the LF / Eject correction pattern.
Click LF/EJECT of the Service Tool on the connected computer, select the paper source and the
paper type, and print the pattern. 5 sheets of paper will be used for the pattern printing.
- Paper source: Select either Rear tray or Cassette.
- Media type: Select one from HR-101, GF-500/Office Planner, HP Bright White, and
Canon Extra/STEINBEIS.
2) When printing is finished, the machine returns to be ready for selection of another function
("Service Mode Idle" is displayed on the LCD).
3) In the printout, determine the Pattern No. in which streaks or lines are the least noticeable for the
LF check pattern and the Eject check pattern respectively. (LF Pattern No. 0 to 4, Eject Pattern
No. 0 to 4)
(10/58)
(11/58)
4) In the LF/EJECT Correction section of the Service Tool, select the Pattern No. (from 0 to 4)
determined in step 3) for LF and EJECT respectively, and click Set.
5) The selected LF and Eject correction values are written to the EEPROM, making the E-MIP
correction value (which was set at shipment from the production site) invalid.
Note: At the production site, the E-MIP correction, which is equivalent to the LF / Eject correction,
is performed using the special tool, and the E-MIP correction value is written to the EEPROM
as the valid data.
When LF / Eject correction is performed, the LF / Eject correction values become valid
instead of the E-MIP correction value (thus, in the initial EEPROM information print, "LF = *"
and "EJ = *" are printed, but the selected values are printed after the LF / Eject correction).
< Button and LCD test >
Confirm the operation after replacement of the operation panel unit, board, or LCD unit.
1) Click Panel Check of the Service Tool on the connected computer. The machine LCD turns blue,
waiting for a button to be pressed.
2) Press each button of the operation panel.
3) Only one button should be pressed at one time. If 2 or more buttons are pressed at the same time,
only one of them is considered to be pressed, and the other buttons are ignored.
The LCD is divided into 16 segments, representing each button. The color of a segment
corresponding to the pressed button changes to red.
1: ON button 9: Color button
2: Back button 10: Stop button
3: OK button 11: NAVI button
4: Up cursor button 12: HOME button
5: Down cursor button 13: Left function button
6: Left cursor button 14: Right function button
7: Right cursor button 15: [+] button
8: Black button 16: [-] button
4) Rotate the Easy-Scroll Wheel clockwise and counterclockwise 1 round (16 steps) each, as
follows:
4-1) Rotate the Easy-Scroll Wheel clockwise step by step. The LCD is divided into 16 segments,
representing each step. The color of a segment corresponding to the step changes from red
to green.
If the wheel is rotated counterclockwise before clockwise round completes, the color of
segment(s) corresponding to the number of steps the wheel is rotated counterclockwise
returns to red.
If the wheel keeps rotated clockwise over 1 round (16 steps), the color of segment(s)
corresponding to the extra number of steps returns to red, starting with the "Start" segment
in the figure below.
(12/58)
4-2) When the Easy-Scroll Wheel is rotated clockwise 1 round (16 steps), press the OK button.
4-3) Rotate the Easy-Scroll Wheel counterclockwise step by step. The LCD is divided into 16
segments, representing each step. The color of a segment corresponding to the step
changes from green to blue.
If the wheel is rotated clockwise before counterclockwise round completes, the color of
segment(s) corresponding to the number of steps the wheel is rotated clockwise returns to
green.
If the wheel keeps rotated counterclockwise over 1 round (16 steps), the color of
segment(s) corresponding to the extra number of steps returns to green, starting with the
"Start" segment in the figure below.
4-4) When the Easy-Scroll Wheel is rotated counterclockwise 1 round (16 steps, and all the
segments are in blue), press the OK button. The color pattern is displayed on the LCD.
If there is any segment that is not in blue when the OK button is pressed, the display
remains unchanged.
5) Adjust the transparent color, as follows:
5-1) Press the OK button. "OK1" in white is displayed on the black background.
If the result is not good, "NG1" in black is displayed on the white background (transparent
color) immediately after "OK1."
(13/58)
5-2) Press the OK button. "OK2" in black is displayed on the white background.
If the result is not good, "NG2" in white is displayed on the black background (transparent
color) immediately after "OK2."
6) Adjust the LCD flicker, as follows:
6-1) Press the OK button. The screen is displayed as below for LCD flicker adjustment.
6-2) If the screen flickers, press the left or right cursor button until the flickering disappears. By
pressing the left or right cursor, the VrefPWM value displayed at the bottom of the LCD
changes from 36 to 3D (in hexadecimal).
6-3) Press the OK button. The machine returns to be ready for selection of another function
("Service Mode Idle" is displayed on the LCD).
< Ink absorber counter setting >
Set the ink absorber counter value to a new EEPROM after the logic board is replaced in servicing.
1) Before replacement of the logic board, check the ink absorber counter value in EEPROM
information print.
2) After replacement of the logic board, the ink absorber counter value should be set in the service
mode using the Service Tool.
In the Ink Absorber Counter section of the Service Tool, select Main from the Absorber
pull-down menu.
From the Counter Value(%) pull-down menu, select the value (in 10% increments) which is the
closest to the actual counter value confirmed before replacement of the logic board, and click Set.
3) Print EEPROM information to confirm that the value is properly set to the EEPROM.
