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 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 12V power source trouble
Remedy: Check connection of the harness and connector. Replace PCU PWB. Replace the power unit. Replace the controller connection mother board.
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 FAX 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: U1-02
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.
