Code :

Code: L3-00
Description: Scanner return trouble
When the mirror base is returned for the specified time (6 sec) in mirror initializing after turning on the power, the mirror home position sensor (MHPS) does not turn ON. Or when the mirror base is returned for the specified time (about 6 sec) after start of copy return, the mirror home position sensor (MHPS) does not turn ON.
Causes: Mirror unit abnormality Scanner wire disconnection Origin detection sensor abnormality Mirror motor harness abnormality

Code: L4-01
Description: Main motor lock detection
When the main motor encoder pulse is not detected for 100 msec.
Causes: Main motor unit abnormality Improper connection or disconnection the main motor and the harness. MCU PWB abnormality

Code: L4-32
Description: Exhaust fan motor lock detection trouble
The error detection is started after 2 sec from starting rotation of the exhaust fan motor. 1) The continuous rotation state of 250ms is not detected for 1 sec after starting detection. 2) When the lock sensor (in the exhaust fan) detects the HIGH level (unstable) after detection the lock state (stable state).
Causes: Exhaust fan motor connector connection trouble Exhaust fan motor trouble MCU PWB trouble

Code: L6-10
Description: Polygon motor lock detection
The lock signal (specified rpm signal) does not return within a certain time (about 20 sec) from starting the polygon motor rotation.
Causes: Polygon motor unit abnormality Improper connection or disconnection of the polygon motor and the harness. MCU PWB abnormality
