Trouble code list for Sharp AR-5516 / AR-5520

Details of trouble codes

E7 01 Duplex model memory error/ Image data error
Detail:
1. The memory capacity for the duplex model machine is wrong. Insufficient memory capacity.
2. Duplex setting is set for a single surface model.
Cause:
1. The memory capacity on the MCU PWB is wrong.
2. Setting for a single surface model is wrong.
Check and remedy:
1. Use SIM26-39 to check to confirm that the memory capacity is 64MB. If it is not 64MB, replace the MCU PWB.
2. If SIM26-04 is set to 1, change the setting to 0. If it is 0, replace the MCU PWB.
E7 02 LSU trouble
Detail:
The BD signal from the LSU cannot be detected in a certain cycle. (Always OFF or always ON)
Cause:
LSU connector or LSU harness defect or disconnection.
Polygon motor rotation abnormality.
Laser beams are not generated.
MCU PWB abnormality.
Check and remedy:
Check connection of the LSU connector.
Execute SIM 61-03 to check the LSU operations.
Check that the polygon motor rotates normally.
Check that the laser emitting diode generates laser beams.
Replace the LSU unit.
Replace the MCU PWB.
E7 06 Image data decode error
Detail:
Image expansion error.
Cause:
MCU PWB abnormality; USB cable trouble.
Check and remedy:
Replace the MCU PWB; Replace the USB cable.
