Code :

Code: L1-00
Description: Feeding is not completed within the specified time after starting feeding. (The scan head locking switch is locked)
The white area and the black marking on the shading plate are used to obtain the difference in the CCD level values for judgment of lock. When the difference in the levels of which and black is small, it is judged that the black mark could not be scanned by lock and the trouble code “L1” is displayed
Causes: The scan head is locked by the lock switch. Mirror unit abnormality The scanner wire is disconnected. The origin detection sensor abnormality Mirror motor harness abnormality

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: 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

Code: U2-04
Description: EEPROM read/write error (Serial communication error)
EEPROM access process error
Causes: EEPROM abnormality

Code: U9-99
Description: Operation panel language error
There is no language file. The language file is destroyed
Causes: Language file abnormality MCU PWB abnormality
