Details of trouble
E7
01
Content Duplex model memory setup error, memory
not-detected error
Detail
The memory is not set properly or the
memory capacity is not set to the duplex
setup (6M).
Check
and
remedy
Set SIM 26-39 code number to 2.
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
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
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
and
remedy
Check connection of the CCD unit flat
cable.
Check the CCD unit.
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 ADF scan position.)
Improper installation of the mirror unit
Check
and
remedy
Clean the mirror, lens, and the reference
white plate.
Check the light quantity and lighting status
of the copy lamp (SIM 05-03).
Check the MCU PWB.
16
Content Abnormal laser output
Detail
When the laser output is stopped, HSYNC
is detected.
Cause
Laser abnormality
MCU PWB abnormality.
Check
and
remedy
Check the laser emitting diode operation.
Replace the MCU PWB.
F2
02
Content Toner supply abnormality
Detail
The maximum toner supply time is greatly
exceeded.
Cause
CRUM chip trouble
Improper developing unit
Check
and
remedy
Replace the CRUM chip.
Replace the developing unit.
04
Content Improper cartridge (Destination error, life
cycle error)
Detail
The destination of the main unit differs from
that of the CRUM.
When the life cycle information is other
than Not Used (FFh).
Cause
CRUM chip trouble
Improper developing unit
Check
and
remedy
Replace the CRUM chip.
Replace the developing unit.
