2.Details of trouble codes
Main Sub
code code
E7 01 Content 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 1. Use SIM26-39 to check to confirm that the
and memory capacity is 64MB. If it is not 64MB,
remedy 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.
02 Content 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 Check connection of the LSU connector.
and Execute SIM 61-03 to check the LSU
remedy 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.
06 Content Image data decode error
Detail Image expansion error
Cause MCU PWB abnormality
USB cable trouble
Check Replace the MCU PWB.
and Replace the USB cable.
remedy
10 Content Shading trouble (Black correction)
Detail The CCD black scan level is abnormal when
the shading.
Cause Improper connection of the CCD unit flat cable
CCD unit abnormality
MCU PWB abnormality.
Check Check connection of the CCD unit flat cable.
and Check the CCD unit.
remedy
11 Content Shading trouble (White correction)
Detail The CCD white scan level is abnormal when
the shading.
Cause Improper connection of the CCD unit flat cable
Dirt on the mirror, the lens, and the reference
white plate
Copy lamp lighting abnormality
CCD unit abnormality
MCU PWB abnormality
(When occurred in the SPF scan position.)
Improper installation of the mirror unit
Check Clean the mirror, the lens, and the reference
and white plate.
remedy Check lighting and the light quantity of the copy
lamp (SIM05-03).
Check the CCD unit.
Check the MCU PWB.
