Content
Sub heater lamp abnormally low
temperature detection
Details
The setup temperature (about –25°C: Sim
43-1-1) is not reached within the specified
time (about 32sec) from turning on the
power.
A/D value of fusing sub thermistor is not
reached within the specified temperature
(specified temperature : SIM43-1 (600dpi)
–25°C )
Cause
Sub thermistor defect.
Sub heater lamp failure.
Sub thermostat failure.
Control PWB failure.
Check
and
remedy
Check the sub heater lamp blinking with
SIM 5-2-2.
When the lamp blinks normally:
Check the thermistor and the harness.
Check the MCU PWB thermistor input
circuit.
If lamp lights and stays lit:
Check the power circuit and the lamp
control circuit on MCU PWB.
Clear the display of self-diagnostics with
SIM 14.
Check that there is no foreign material in
the contact section between the thermistor
and the heat roller.

Content
10 times of continuous detection of the
lower paper exit sensor (POD1) lead edge
jam or the upper paper exit sensor (POD2)
lead edge jam or the duplex sensor
(PPD2) rear edge jam
Details
After supplying the power, one of the
above jams occurs 10 times continuously
in printing
Counting is started on supplying the
power. When any one of the above jams
occurs, one count is made. When paper
entry to the POD1 or POD2 is detected,
the counter is cleared.
Cause
A paper jam (paper rounding, etc.) near
the duplex sensor (PPD2) on the fusing
unit is not canceled completely.
POD1, POD2, PPD2 sensor breakdown or
harness connection trouble
Fusing unit installation failure
Check
and
remedy
Check for jam paper in the fusing section.
(paper winding, etc.)
Check fusing unit installation.
Check the POD1, POD2 or PPD2 sensor.
Clear the trouble with SIM 14.

Content
Scanner return trouble
Details
Scanner return is not completed within the
specified time.
When OC copying with the mirror at the
home position, the mirror is not in the
home position.
Cause
Mirror unit defect.
The scanner wire is disconnected.
Origin detection sensor error.
Mirror motor harness abnormality.
Check
and
remedy
Check the scanning operation with SIM 1-
1.
When the mirror fails to return:
Check for disconnection of the scanner
wire.
Check the harness and connector between
the mirror motor and the MCU PWB.
Replace the mirror unit.
Replace the MCU PWB.
When the mirror feeds:
Check the mirror home position sensor
with SiM 1-2.

or more after the main motor rotates.
The motor lock signal is detected for 1sec
during rotation of the main motor.
Cause
Main motor defect.
Main motor connection, harness trouble or
disconnection.
MCU PWB failure.
Check
and
remedy
Check the main motor operation with SIM
25-1.
Check connection of the main motor
harness and connector.
