APPENDIX 1
1.1 When PCB is replaced
The information below is stored in NV-RAM (EEPROM) on ESS.
If necessary, transfer the data to a new PCB.
- U8 (Part number)
1. Data set with Control Panel
2. NV-RAM data on MCU that is saved manually
3. Error Log
4. Jam Log
5. Billing Counter
- U9 (Part number)
The information stored is specific to the Controller Board, therefore, the
information cannot be used for the new PCB.
- U7/U38 (Part number)
Job Log is stored, however, the Job Log cannot be transferred to the new PCB
because it is surface-mounted.
 The Network setting data is stored in EEPROM on NIC EXCORD ASSY. Use the
same NIC EXCORD ASSY if you want to keep the same Network setting.
