<LF / Eject correction>
After replacement of the feed roller, logic board, or platen unit in repair servicing or in refurbishment operation, perform the
adjustment to maintain the optimal print image quality.
Details: Print the LF / Eject correction pattern on a sheet of paper. Select the Pattern No. (0 to 2) in which streaks or lines
are the least noticeable, press the Stop/Reset button the same number of time(s) as the selected Pattern No., then
press the ON/OFF button. (See the flowchart below.)
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).
1) In the LF / Eject correction mode, press the Stop/Reset button the specified number of time(s) according to the paper to be
used in LF / Eject correction listed in the table below, then press the ON/OFF button. (Set a sheet of selected paper in the
cassette.)
Time(s) (L)

- Each time the Stop/Reset button is pressed, the Alarm and Power LEDs light alternately, Alarm in orange and
Power in green.
- If the Stop/Reset button is NOT pressed, and only the ON/OFF button is pressed, the machine remains in the
LF / Eject correction mode.
- If the Stop/Reset button is pressed 5 times or more, then the ON/OFF button is pressed, the machine returns to
the service mode menu selection.
