- 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.
