Sharp MXC380P

• Code: U2-24
• Description: MFP PWB SRAM memory user authentication counter check sum error
• Causes: MFP PWB SRAM trouble. MFP PWB trouble. Strong external noises.
• Remedy: Use SIM16 to cancel the error. Error cancel method SIM16

• Code: U2-30
• Description: MFP PWB and PCU PWB manufacturing No. data inconsistency
• Causes: Inconsistency between the manufacturing No. saved in the PCU PWB and that in the MFP PWB. When replacing the PCU PWB or the MFP PWB, the EEPROM which was mounted on the PWB before replacement is not mounted on the new PWB. MFP PWB trouble. PCU PWB trouble
• Remedy: Check that the EEPROM is properly set. Check to confirm that the EEPROM which was mounted on the PWB before replacement is mounted on the new PWB. Use SIM16 to cancel the error. Replace the MFP PWB. Replace the PCU PWB. Error cancel method SIM16

• Code: U2-90
• Description: PCU PWB EEPROM read/write error
• Causes: PCU PWB EEPROM trouble. Installation of non-initialized EEPROM. PCU PWB trouble EEPROM socket contact trouble.
• Remedy: Replace the PCU PWB EEPROM. Replace the PCU PWB. Check contact of the EEPROM socket. Put down the counter/adjustment values in the simulation to prevent against loss of the counter data and the adjustment values. Use SIM16 to cancel the trouble. Error cancel method SIM16

• Code: U2-91
• Description: PCU PWB EEPROM check sum error
• Causes: PCU PWB EEPROM trouble. Installation of non-initialized EEPROM. PCU PWB trouble EEPROM socket contact trouble.
• Remedy: Replace the PCU PWB EEPROM. Replace the PCU PWB. Check contact of the EEPROM socket. Put down the counter/adjustment values in the simulation to prevent against loss of the counter data and the adjustment values. Use SIM16 to cancel the trouble. Error cancel method SIM16

• Code: U6-00
• Description: PCU PWB - Desk paper feed unit communication error
• Causes: Error when testing the communication line after turning ON the power or canceling the simulation. Connector, harness connection trouble. Desk control PWB trouble. PCU PWB trouble Strong external noises.
• Remedy: Turn OFF/ON the power to cancel. Check the connector and the harness in the communication line. Replace the desk control PWB. Replace the PCU PWB.

• Code: U6-01
• Description: Desk paper feed tray 1 lift trouble
• Causes: D1ULD does not turn ON within the specified time when lift-up operation. D1ULD sensor trouble. Desk control PWB trouble. Lift unit trouble. Connection trouble of the connector and the harness. PCU PWB trouble
• Remedy: Replace the D1ULD sensor. Replace the desk control PWB. Replace the lift unit. Harness and connector connection trouble. Replace the PCU PWB.
