5 continuous POUT not-reached error
Detail
When 5 continuous not-reached jams to the
paper exit sensor (POUT) occur.
The jam counter is backed up and it is used in
a job after turning on the power.
Cause
Jam paper is not removed from the fusing unit.
(Jam paper remains.)
Paper exit sensor breakdown or harness
connection trouble
Fusing unit installation trouble
Check
Check for jam paper remaining in the fusing
and
unit. (winding, etc.)
remedy
Check the POUT sensor harness, and check
installation of the fusing unit.
Use SIM14 to clear the self diag display.

Check
Use SIM 1-1 to check the mirror reciprocating
and
operations.
remedy
When the mirror does not feed.
Check for disconnection of the scanner wire.
Check the harness and the connector between
the mirror motor and the MCU PWB.
Replace the mirror unit.
Replace the MCU PWB.
When the mirror does feed.
Use SIM 1-2 to check the mirror home position
sensor.

After rotation of the main motor, the motor lock
signal is detected for 1 sec or more.
During rotation of the main motor, the motor
lock signal is detected for 1 sec.
When the main motor is stopped, the motor
lock signal is not detected for 5sec or more.
(Though the motor is stationary, it is judged as
stable rotation.)
Cause
Main motor unit abnormality
Improper connection or disconnection the main
motor and the harness.
MCU PWB abnormality
Check
Use SIM 25-01 to check the main motor
and
operations.
remedy
Check connection of the main motor harness/
connector.
Replace the main motor.
Replace the MCU PWB.

or disconnection of the harness, shifter home
position sensor abnormality.
Check
Use SIM 03-11 to check the shifter motor
and
operations.
remedy
Check connection of the harness/connector of
the shifter motor.
Replace the shifter motor.
Replace the MCU PWB.
