MX-FN10 SELF DIAG MESSAGE AND TROUBLE CODE 9 – 6
10. Other sections
Case2
Cause
Saddle pushing plate motor clock sensor
trouble
Check &
Remedy
Measure the voltage at TP66 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
Pushing plate HP sensor trouble
Check &
Remedy
Measure the voltage at TP64 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.
Case4
Cause
Electric cable, connector trouble
Check &
Remedy
Check conduction between connector
terminals. If there is no conduction, replace
the electric cable.
Case5
Cause
Finisher control PWB trouble
Check &
Remedy
If the motor does not operate properly in the
single operation mode, replace the finisher
control PWB. If the trouble remains even
tough the sensor operates properly in the
sensor check, replace the finisher control
PWB.
Phenomenon
Folding operation is not performed properly.
(Paper jams frequently occur in the folding section.)
Case1
Cause
Paper detection 7 sensor trouble
Check &
Remedy
Measure the voltage at TP69 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
Paper detection 5 sensor trouble
Check &
Remedy
Measure the voltage at TP68 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 phenomenon remains though the
sensor is normal, replace the finisher control
PWB.
Phenomenon
Paper empty in the saddle process tray (saddle
alignment tray) is not detected properly.
Case1
Cause
Paper detection 7 sensor trouble
Check &
Remedy
Refer to the other item (Folding operation is
not performed properly.) in this sheet..
Case2
Cause
Electric cable, connector trouble
Check &
Remedy
Refer to the other item (Folding operation is
not performed properly.) in this sheet..
Case3
Cause
Finisher control PWB trouble
Check &
Remedy
Refer to the other item (Folding operation is
not performed properly.) in this sheet..
Phenomenon
Paper empty in the saddle accumulation tray is not
detected properly.
Case1
Cause
Paper detection 6 sensor trouble
Check &
Remedy
Measure the voltage at TP65 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.
Phenomenon
Folding operation is not performed properly.
(The saddle pushing plate motor does not operate
properly.)
Case3
Cause
Finisher control PWB trouble
Check &
Remedy
If the phenomenon remains though the
sensor is normal, replace the finisher control
PWB.
Phenomenon
Cover open/close is not detected properly.
Case1
Cause
Interface transport unit cover open/close
sensor trouble
Check &
Remedy
Measure the voltage at TP106 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
Joint sensor trouble
Check &
Remedy
Measure the voltage at TP3 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
Top cover sensor trouble
Check &
Remedy
Measure the voltage at TP30 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.
Case4
Cause
Front door sensor trouble
Check &
Remedy
Measure the voltage at TP61 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.
Case5
Cause
Front cover open/close switch trouble
Check &
Remedy
Measure the voltage at TP91 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.
Case6
Cause
Saddle STP staple replacement switch
trouble
Check &
Remedy
Measure the voltage at TP90 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.
Case7
Cause
Electric cable, connector trouble
Check &
Remedy
Check conduction between connector
terminals. If there is no conduction, replace
the electric cable.
Case8
Cause
Finisher control PWB trouble
Check &
Remedy
If the phenomenon remains though the
sensor is normal, replace the finisher control
PWB.
Phenomenon
The finisher backup RAM does not operate properly.
Case1
Cause
Finisher control PWB trouble
Check &
Remedy
Since the IC of the backup RAM is defective,
replace the finisher control PWB.
Phenomenon
Paper empty in the saddle accumulation tray is not
detected properly.
