Adjustment after replacing parts
Priority for Adjustment/Setting after replacing parts
Conduct the following adjustment on the items list in this order when replacing the parts on the list. Proper operation/image quality is not guaranteed without conducting those adjustment after the parts replacement.
Note
- When replacing the image processing board (IPB) due to the IPB being damaged, be sure to use the NVRAM board (NRB) that was installed on the damaged IPB on the new IPB. Contact the service manager of the authorized distributor if it is considered that NRB is also damaged.
- The NVRAM board (NRB) stores various adjustment data, setting data and counter data. Therefore, when replacing the PB, perform all adjustments and settings, and be sure to replace the parts for control correction (Drum, developer, cleaning blade, cleaning web). For details, contact the service manager of the authorized distributor.
- When replacing a board due to PB control board (PBCB), SD control board (SDCB), FD control board (FDCB), RU control board (RUCB) or FNS control board (FNSCB) being damaged, be sure to use the non-volatile memory (EEPROM) that was installed on the damaged control board on the new control board. Install the new EEPROM and perform all adjustments for the PB, SD, FD, RU or FS if it is considered that the EEPROM is also damaged.
