Description: NV-RAM error - Normal read/write from/to NVM (EEPROM) on the MCU PWB cannot be performed. - The MCU PWB (or X-ROM PWB) was replaced in error.
Causes: • MCU PWB • X-ROM PWB
Remedy: 1 Check of the MCU PWB Turn the main power off and then back on. Does the error occur again after the power is turned on? To Step 2 Problem solved 2 Check of the MCU PWB Turn the main power on and off several times. Does the error occur? To Step 3 Problem solved 3 Replacement of the EEPROM Replace the EEPROM on the MCU PWB. Does the error occur? To Step 4 Make adjustments that are indicated by adjustment icons. 4 Replacement of the MCU PWB After putting the removed EEPROM back to the place, replace the MCU PWB. Does the error occur? Put the removed MCU PWB back and then replace the X-ROM PWB. Problem solved Do not replace both the EEPROM and X-ROM PWB at one time. Doing so makes the printer unable to start up. When have replaced one of them, the stored data will be downloaded to the newly installed one from the other. (From EEPROM to X-ROM PWB, or From X-ROM PWB to EEPROM) Therefore, when replacing the EEPROM or the X-ROM PWB, be sure about the followings. • When replacing EEPROM: X-ROM PWB and MCU PWB should be those that originally come with the printer. • When replacing X-ROM PWB: EEPROM and MCU PWB should be those that originally come with the printer. Be sure to perform the followings after replacing the EEPROM. “5.1.2 Part/unit-based adjustment items” • Color Registration Adjustment • Writing correction values of the followings • Sensor Assy TP • Motor Disp (for 4 colors)
