MX-FN10 SELF DIAG MESSAGE AND TROUBLE CODE 9 – 5
8. Saddle staple unit
9. Saddle folding section
Phenomenon
The saddle rear edge pushing plate shift motor does
not operate properly.
Case1
Cause
Saddle rear edge pushing plate shift motor
trouble
Check &
Remedy
Check conduction of the coil. If there is no
conduction, replace.
Case2
Cause
Movable pushing HP sensor trouble
Check &
Remedy
Measure the voltage at TP12 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
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
Poor alignment of paper in the saddle process tray
(The saddle alignment plate motor does not operate
properly.)
Case1
Cause
Saddle alignment plate motor trouble
Check &
Remedy
Check conduction of the coil. If there is no
conduction, replace.
Case2
Cause
Saddle alignment plate HP sensor
Check &
Remedy
Measure the voltage at TP70 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
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
Poor alignment of paper in the saddle process tray
(The saddle No. 3 roller drive motor does not operate
properly.)
Case1
Cause
Saddle No. 3 roller drive motor trouble
Check &
Remedy
Check conduction of the coil. If there is no
conduction, replace.
Case2
Cause
Saddle No. 3 roller nip separation sensor
trouble
Check &
Remedy
ÅBMeasure the voltage at TP67 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
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
The center binding staple motor does not operate
properly.
Case1
Cause
Center binding staple motor trouble
Check &
Remedy
Check conduction of the coil. If there is no
conduction, replace the staple unit.
Case2
Cause
Cam switch trouble
Check &
Remedy
Measure the voltage at TP20 on the finisher
control PWB to confirm that it is 1V or less
when it is ON, and 3.3V
5% when it is OFF. If
the voltage is outside the range, replace the
staple unit.
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
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
The stapler slide motor does not operate properly.
Case1
Cause
Stapler slide motor trouble
Check &
Remedy
Refer to the other sheet (Staple unit).
Case2
Cause
Stapler slide sensor (edge binding) trouble
Check &
Remedy
Refer to the other sheet (Staple unit).
Case3
Cause
Stapler slide sensor (center binding) trouble
Check &
Remedy
Refer to the other sheet (Staple unit).
Case4
Cause
Stapler catch prevention sensor trouble
Check &
Remedy
Refer to the other sheet (Staple unit).
Case5
Cause
Electric cable, connector trouble
Check &
Remedy
Refer to the other sheet (Staple unit).
Case6
Cause
Finisher control PWB trouble
Check &
Remedy
Refer to the other sheet (Staple unit).
Phenomenon
Though saddle clinging is performed, no staple is
provided or the machine goes into the staple empty
state.
Case1
Cause
Staple empty switch trouble
Check &
Remedy
Measure the voltage at TP72 on the finisher
control PWB to confirm that it is 1V or less
when it is ON, and 3.3V
5% when it is OFF. If
the voltage is outside the range, replace the
staple unit.
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 phenomenon remains though the
sensor is normal, replace the finisher control
PWB.
Phenomenon
Folding operation is not performed properly.
(The saddle pushing plate motor does not operate
properly.)
Case1
Cause
Saddle pushing plate motor trouble
Check &
Remedy
Check conduction of the coil. If there is no
conduction, replace.
