• Code: L6-10
• Description: Polygon motor lock detection
  It is judged that the polygon motor lock signal is not outputted. Lock signal is checked in the interval of 10sec after starting the polygon motor, and it is judged that the polygon motor does not rotate normally.
• Causes: The LSU connector or harness in the LSU is disconnected or broken. Polygon motor trouble
• Remedy: Use DIAG (SIM61-1) to check the polygon motor operation. Check connector and harness connection. Replace LSU.

• Code: L8-01
• Description: No fullwave signal
  Full wave signal is not detected.
• Causes: The PCU PWB connector or the power unit harness is disconnected or broken. PCU PWB trouble Power unit trouble
• Remedy: Check connection of the harness and connector. Replace PCU PWB. Replace the power unit.

• Code: L8-02
• Description: Full wave signal width abnormality
  It is judged as full wave signal frequency abnormality. (When the detection cycle is judged as 69Hz or above or 42.5Hz or below)
• Causes: The connector or harness of the PCU PWB and the power PWB is disconnected. PCU PWB trouble Power unit trouble
• Remedy: Check connection of the harness and connector. Replace the PCU PWB. Replace the power unit.

• Code: PF-00
• Description: RIC copy inhibit signal is received.
  Copy inhibit command from RIM (host) is received.
• Causes: Judged by the host.
• Remedy: Inform to the host.

• Code: U1-01
• Description: FAX Battery abnormality
  Backup SRAM battery voltage fall
• Causes: Battery life Battery circuit abnormality
• Remedy: Check that the battery voltage is about 2.5V or above. Check the battery circuit.

• Code: U102
• Description: RTC read abnormality (common with FAX, on ICU PWB)
  The value read from RTC on ICU PWB is [EE]h (abnormal).
• Causes: RTC circuit abnormality Battery voltage fall Battery circuit abnormality
• Remedy: Set the time again with key operation, and check that time advances properly. Check RTC circuit. Check that battery voltage is about 2.5V or above. Check battery circuit.

• Code: U2-00
• Description: EEPROM read/write error (Controller)
  EEPROM write error
• Causes: EEPROM trouble EEPROM is not initialized. Controller PWB EEPROM access circuit trouble
• Remedy: Check that EEPROM is properly inserted. Save the counter/adjustment values with the DIAG simulation. Use DIAG (SIM16) to cancel U2 trouble. Replace the Controller PWB.

• Code: U2-11
• Description: Counter check sum error (Controller)
  Counter data area check sum error
• Causes: EEPROM trouble Control circuit trouble by noise Controller PWB EEPROM access circuit trouble
• Remedy: Check that EEPROM is properly inserted. Save the counter/adjustment values with the DIAG simulation. Use DIAG (SIM16) to cancel U2 trouble. Replace the Controller PWB.
