Mirror base return trouble
Detail
The mirror home position (MHPS) does
not turn on though the mirror base
returning is completed during mirror
initial operation after turning on the
power.
The mirror home position does not turn
on when the mirror is returned to the
home position during shading.
The mirror home position (MHPS) does
not turn on when the mirror base
returning is completed for the specified
time (about 6 sec) after copy return
start.
Cause
Mirror unit
Mirror home position sensor defect
MCU PWB defect
Scanner wire disconnection
Check and
remedy
Check the scanning operation with SIM
1-1.

Content
Polygon motor lock
Detail
The lock signal (the specified rotation
speed signal) is not supplied within the
specified time (about 6 sec)after
starting the polygon motor rotation.
Cause
LSU connector disconnection or
harness disconnection in the LSU.
Check and
remedy
Check the operation of the polygon
motor with SIM 25-10.
Check the harness and the connector
connection.
