Sharp MXM266N

• Code: U2-60
• Description: Watermark check error
• Causes: Watermark data trouble HDD trouble MFPC PWB trouble
• Remedy: Use SIM16 to cancel the U2 trouble. Use SIM49-5 to install the watermark data. Replace the HDD. Replace the MFPC PWB. (Refer to the pages on the necessary works after replacing the HDD and the MFPC PWB in the Service Manual, and perform the works.)

• Code: U2-80
• Description: SCU PWB EEPROM read/write error
• Causes: SCU PWB EEPROM trouble SCU PWB trouble SCU PWB EEPROM socket connection trouble
• Remedy: Replace the SCU PWB EEPROM. Replace the SCU PWB. Check connection of the SCU PWB EEPROM socket. Check the SIM adjustment value of the following items, and adjust again if they are improper. * Scanner-related adjustments * Touch panel-related adjustments Use SIM16 to cancel the trouble. To avoid missing of the counter data and the adjustment values, use this simulation to save the counter data and the adjustment values. (If there is a printer option, use SIM22-01 to save the counter data and the adjustment values.)

• Code: U2-81
• Description: SCU PWB EEPROM check sum error
• Causes: SCU PWB EEPROM trouble. Installation of non-initialized EEPROM. SCU PWB trouble. EEPROM socket contact trouble
• Remedy: Replace the SCU PWB EEPROM. Replace the SCU PWB. Check contact of the EEPROM socket. Use SIM16 to cancel the trouble. (The check sum error detection data are calculated again to reset the proper check sum data.) To avoid missing of the counter data and the adjustment values, use this simulation to save the counter data and the adjustment values. (If there is a printer option, use SIM22-01 to save the counter data and the adjustment values.)

• Code: U2-90
• Description: PCU PWB EEPROM read/write error
• Causes: PCU PWB EEPROM trouble PCU PWB trouble EEPROM socket contact trouble
• Remedy: Replace the PCU PWB EEPROM. Check the SIM adjustment values of the engine, and adjust again if they are improper. Replace the PCU PWB. Check contact of the EEPROM socket. Use SIM16 to cancel the trouble. To avoid missing of the counter data and the adjustment values, use this simulation to save the counter data and the adjustment values. (If there is a printer option, use SIM22-01 to save the counter data and the adjustment values.)

• Code: U2-91
• Description: PCU PWB EEPROM check sum error
• Causes: PCU PWB EEPROM trouble PCU PWB trouble EEPROM socket contact trouble
• Remedy: Replace the PCU PWB EEPROM. Replace the PCU PWB. Check contact of the EEPROM socket. Use SIM16 to cancel the trouble. (The check sum error detection data are calculated again to reset the proper check sum data.) To avoid missing of the counter data and the adjustment values, use this simulation to save the counter data and the adjustment values. (If there is a printer option, use SIM22-01 to save the counter data and the adjustment values.)

• Code: U7-50
• Description: MFPC PWB - Vendor machine communication error
• Causes: Improper setting of the vendor machine specifications (SIM26-3). Vendor machine trouble. MFPC PWB trouble. Connector, harness connection trouble. Strong external noises.
• Remedy: Cancel the error by turning OFF/ON the power. Check the connector and the harness in the communication line. Change the specifications of the vendor machine (SIM26-3). Replace the MFPC PWB.
