< 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.

(13/24)
2) When printing is finished, the printer returns to be ready for selection of another function.
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)
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).
<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.
<CD / DVD print position correction>
Set the CD / DVD print position value to a new EEPROM after the logic board is replaced in
servicing.
Note: For solution of user complaints, this function can be used, however, use of the application
software is recommended to adjust the CD / DVD print position.

(14/24)
1) Before replacement of the logic board, check the CD / DVD print position value in EEPROM
information print.
2) After replacement of the logic board, set the print position value in CD-R Correction of the
Service Tool.
3) If EEPROM information is not available before replacement of the logic board due to logic board
failure, etc., click CD-R in the Service Tool to print the CD-R check pattern, and confirm that the
intersection of the axes Y and X is at the center of the CD / DVD.

Function Procedures Remarks
Nozzle check pattern
printing Perform from the printer driver Maintenance tab, or see
"Standalone printer operation"
below.
Set a sheet of plain paper (A4 or Letter) in
the cassette, or the rear tray if selected.
Print head manual
cleaning Perform from the printer driver Maintenance tab.
- Cleaning of both Black and Color
- Cleaning Black or Color separately
Unclogging of the print head nozzles, and
maintenance to keep the print head
conditions good.
If there is a missing portion or white streaks
in the nozzle check pattern printout,
perform this cleaning.
Print head deep
cleaning Perform from the printer driver Maintenance tab. If print head cleaning is not effective, perform this cleaning. Since the deep
cleaning consumes more ink than regular
cleaning, it is recommended to perform
deep cleaning only when necessary.
Automatic print head
alignment Perform from the printer driver Maintenance tab. Set 1 sheet of A4 Matte Photo Paper (MP-101) in the rear tray.
If automatic alignment is not effective,
perform manual print head alignment.
Manual print head
alignment Perform from the printer driver Maintenance tab. Set 3 sheets of plain paper (A4 or Letter) in the cassette, or the rear tray if selected.
Print head alignment
value printing Perform from the printer driver Maintenance tab. Confirmation of the current print head alignment values.
Paper feed roller
cleaning Perform from the printer driver Maintenance tab. The paper feed rollers of the selected paper source (the rear tray or the cassette)
rotate while being pushed to the paper
lifting plate. Since the rollers will wear out in
this cleaning, it is recommended that you
perform this only when necessary.
Bottom plate cleaning Perform from the printer driver
Maintenance tab, or see
"Standalone printer operation"
below.
Cleaning of the platen ribs when the back
side of paper gets smeared.
Fold a sheet of plain paper (A4 or Letter) in
half crosswise, then unfold and set it in the
rear tray with the folded ridge facing down.
(No paper feeding from the cassette)
< Standalone printer operation >
1) Turn on the printer in the user mode.
