Sharp MX-FN10 - Staple Unit Issues; Saddle Transport Load Section Issues

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.
