Adjustment and correction of color registration are always required for each part replacement.

Re-mounting the EEPROM used on the board before the replacement. *Note
Re-mounting the EEPROM used on the board before the replacement. *Note
Setting the correction value of the calibration chip for detecting density.
Adjusting paper thickness detection sensitivity and checking media
thickness detection value setting.
* Note:1. When the EEPROM of PU (K7N board) is replaced to a new one, color balance must
be adjusted.
* Note: 2. When the EEPROM of CU (TIG board) is replaced to a new one, the Destination
Setting must be adjusted.
3.2.1 Precautions in replacing the engine control board
When replacing the engine control board , remove the EEPROM from the old board
and mount it on a new board (for errors other than those of engine EEPROM).
When SERVICE CALL xxx (Engine EEPROM Error) is displayed on the operator panel, the
EEPROM must be replaced with a new one. In this case, perform the operation described in section
3.2.2.
3.2.2 Precautions in replacing EEPROM
When the EEPROM is not removed from the board and placed on the new board at the time of
engine controll board replacement, the Version Read function (fuse cut) is disabled.
The printer must be switched from the factory mode to the shipping mode by the PJL command.
[Description]
1. Sending of an appropriate PJL file to the printer to place it in Shipping mode
2. Sending of a repower-on or reboot command (PJL file) to complete the setting
[Procedure]
At the MS-DOS prompt, perform the following steps:
1. Enter Copy /b Pjl_ship.bin prn and hit <Enter>.
2. Enter Copy /b Pjl_reboot.bin prn and hit <Enter>, or power the printer off and on.
[Pjl Files Required]
1. Pjl-ship.bin
2. Pjl-reboot.bin
Note: Life data for consumables such as belt, toner, and ID is cleared when replacing EEPROM,
therefore, be cautious as there will be a tolerance in life management upon replacing the
unit in the future. The following count will be cleared when replacing EEPROM.
Other than Total Sheets Feed is cleared when each unit is replaced, therefore, the
tolerance will be cleared at that point.
