(3) 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.

If the print quality is considered unaffected by replacement of those parts, it is not necessary to perform LF /

Eject correction.

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 A4 paper will be used for the pattern printing.

- Paper source: Select either

Rear tray

Cassette

- Media type: Select one from

HR-101

GF-500/Office Planner

HP Bright White

, and

Canon Extra/STEINBEIS

2) When printing is finished, "A function was finished" is displayed on the computer, and the machine

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) Select and set the correction values.

In the

LF/EJECT Correction

section of the Service Tool, select the Pattern No. (from 0 to 4)

determined in step 3) for

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).
