MX-FN10 SELF DIAG MESSAGE AND TROUBLE CODE 9 – 2
3. Transport section except for the
saddle
4. Process tray
Phenomenon The rear edge sensor and the resist sensor do not
operate properly.
Case1 Cause Rear edge sensor trouble
Check &
Remedy If ON/OFF operation is not made in the punch
single sensor check mode, replace the PWB
assembly on the light emitting side and the
light receiving side. If the trouble still remains,
replace the punch control PWB.
Case2 Cause Resist sensor (SIZE A3) trouble
Check &
Remedy If ON/OFF operation is not made in the punch
single sensor check mode, replace the PWB
assembly on the light emitting side and the
light receiving side. If the trouble still remains,
replace the punch control PWB.
Case3 Cause Resist sensor (SIZE B4) trouble
Check &
Remedy If ON/OFF operation is not made in the punch
single sensor check mode, replace the PWB
assembly on the light emitting side and the
light receiving side. If the trouble still remains,
replace the punch control PWB.
Case4 Cause Resist sensor (SIZE A4) trouble
Check &
Remedy If ON/OFF operation is not made in the punch
single sensor check mode, replace the PWB
assembly on the light emitting side and the
light receiving side. If the trouble still remains,
replace the punch control PWB.
Case5 Cause Resist sensor (SIZE B5) trouble
Check &
Remedy If ON/OFF operation is not made in the punch
single sensor check mode, replace the PWB
assembly on the light emitting side and the
light receiving side. If the trouble still remains,
replace the punch control PWB.
Case6 Cause Electric cable, connector trouble
Check &
Remedy Check conduction between connector
terminals. If there is no conduction, replace
the electric cable.
Phenomenon The dust sensor does not operation properly.
Case1 Cause Dust sensor trouble
Check &
Remedy If ON/OFF operation is not made in the punch
single sensor check mode, replace the PWB
assembly on the light emitting side and the
light receiving side. If the trouble still remains,
replace the punch control PWB.
Case2 Cause Electric cable, connector trouble
Check &
Remedy Check conduction between connector
terminals. If there is no conduction, replace
the electric cable.
Phenomenon The punch backup RAM does not operate properly.
Case1 Cause Punch control PWB trouble
Check &
Remedy If it does not operate properly in the punch
RAM check mode, replace the punch control
PWB.
Phenomenon The transport motor 1 does not operate properly.
Case1 Cause Transport motor 1 trouble
Check &
Remedy Check conduction of the coil. If there is no
conduction, replace it.
Case2 Cause Connector trouble
Check &
Remedy Check connection of the connector. (Finisher
control PWB: CN12)
Case3 Cause Finisher control PWB trouble
Check &
Remedy If the motor does not operate properly in the
motor single operation mode, replace the
finisher control PWB. If the trouble still
remains, replace the finisher control PWB.
Phenomenon The transport motor 2 does not operate properly.
Case1 Cause Transport motor 2 trouble
Check &
Remedy Check conduction of the coil. If there is no
conduction, replace it.
Case2 Cause Electric cable, connector trouble
Check &
Remedy Check conduction between connector
terminals. If there is no conduction, replace
the electric cable.
Case3 Cause Finisher control PWB trouble
Check &
Remedy If the motor does not operate properly in the
motor single operation mode, replace the
finisher control PWB. If the trouble still
remains, replace the finisher control PWB.
Phenomenon Paper jams frequently occur in the finisher transport
section.
Case1 Cause Paper detection 1 sensor trouble
Check &
Remedy Measure the voltage at TP1 on the finisher
control PWB to confirm that it is 1V or less
when transmitting, and 3.3V

5% when
interrupted. If the voltage is outside the range,
replace the sensor.
Case2 Cause Electric cable, connector trouble
Check &
Remedy Check conduction between connector
terminals. If there is no conduction, replace
the electric cable.
Case3 Cause Finisher control PWB trouble
Check &
Remedy When the sensor is turned ON/OFF, if the
phenomenon still remains though the sensor
level is changed, replace the finisher control
PWB.
Phenomenon The paper exit lift guide motor does not operate
properly.
Case1 Cause Paper exit lift guide motor trouble
Check &
Remedy Check conduction of the coil. If there is no
conduction, replace it.
Case2 Cause Paper exit roller nip separation sensor trouble
Check &
Remedy Measure the voltage at TP31 on the finisher
control PWB to confirm that it is 1V or less
when transmitting, and 3.3V

5% when
interrupted. If the voltage is outside the range,
replace the sensor.
Case3 Cause Electric cable, connector trouble
Check &
Remedy Check conduction between connector
terminals. If there is no conduction, replace
the electric cable.
Case4 Cause Finisher control PWB trouble
Check &
Remedy If the motor does not operate properly in the
motor single operation mode, replace the
finisher control PWB. Also in the sensor
check, if it is normal but the trouble still
remains, replace the finisher control PWB.
Phenomenon Poor alignment of paper on the process tray
(The alignment plate motor does not operate
properly.)
Case1 Cause Front alignment plate motor trouble
Check &
Remedy Check conduction of the coil. If there is no
conduction, replace.
Case2 Cause Rear alignment plate motor trouble
Check &
Remedy Check conduction of the coil. If there is no
conduction, replace.
Case3 Cause Front alignment plate HP sensor
Check &
Remedy Measure the voltage at TP89 on the finisher
control PWB to confirm that it is 1V or less
when transmitting, and 3.3V

5% when
interrupted. If the voltage is outside the range,
replace the sensor.
