Adjustments after Parts Replacement

The following describes the adjustments that are required after replacing parts.
Adjustment and correction for color registration are always required for each part replacement.
Replaced Part
LED Head
Drum Cartridge (Y, M, C, K)
Fuser Unit
Belt Cassette Assy
PU (K7N Board)
CU (TIG board)
CU (HMF/HME board)
Oki LAN8100e (HMN Board)
Shutter
Media Thickness Sensor
Assy
* Note:1. When the EEPROM of the PU (K7N board) is replaced to a new one, color balance
must be adjusted.
* Note: 2. When the EEPROM of the CU board is replaced to a new one, the Destination Setting
must be adjusted.
3.2.1

Precautions in replacing engine control board

When replacing the engine control board (K7N PWB), remove the EEPROM from the old board
and set it on a new board (for errors other than those of engine EEPROM).
When SERVICE CALL xxx (an engine EEPROM error) is displayed on the operator panel, the
EEPROM must be replaced with new EEPROM. 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 (K7N PWB) 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.
