Check item
Check that the cable between the sorter controller
PWB and the bin unit is properly connected.
Check that the cable between the bin paper
sensor light emitting side (S1) and the light
receiving side (S2) is properly connected.
Check that the bin paper sensor light emitting side
(S1) and the light receiving side (S2) are properly
installed.
When the bin paper sensor light emitting side (S1)
and the light receiving side (S2) are replaced and
the bin paper sensor sensitivity adjustment is
performed, the trouble is canceled.
Check item
Check that the circuit breaker on the sorter
controller PWB is operating.
Set the tester range to 50VDC. Check that the
voltage between J1-1 (+) and J1-2 (–) on the
sorter controller PWB is about 24V.
Check that there are pulse outputs at connector
J12-2 to -5 on the sorter controller PWB at the
operating timing of the stapler unit oscillation
motor.
Check that J12-1 is +24V.
Set the tester range to 50VDC. Check that the
voltage between the sorter controller PWB J6-3
(+) and the case (–) is about 24V (when the joint
and the coupler are closed). Check that the
voltage between J6-4 (+) and the case (–) is
about 24V when the stapler oscillation unit is in
the home position, and 0V when it is not.
Check item
Check that the cable between the bin shift motor
and the sorter controller PWB is properly
connected.
Check that the circuit breaker (CB1) on the sorter
controller PWB is operating.
Set the tester range to 50VDC. Check that the
voltage between the sorter controller PWB J1-1
(+) and J1-2 (–) is about 24V.
Check that the voltage between the connector
J8-1 and J8-2 on the bin shift motor driver PWB is
about 24V at the operating timing of the bin shift
motor (M1).
Check item
Check that there is anything on the key or not.
Press a key and check that the switch on the
operation PWB is pressed or not.
Check the cable connection between the sorter
control PWB and the operation PWB.
Result
NO Connect properly.
NO Connect properly.
NO Connect properly.
When the bin paper sensor light emitting side (S1) and the light
receiving side (S2) are installed again, perform the bin paper
sensor sensitivity adjustment. (For the procedure, refer to page
5-1)
YES Replace the bin paper sensor light emitting side (S1) and the
light receiving side (S2) and perform the bin paper sensor
sensitivity adjustment. (For the procedure, refer to page 5-1)
NO Replace the sorter controller PWB, and perform the bin paper
sensor sensitivity adjustment, the guide bar motor oscillation
range adjustment, and the stapler motor oscillation motor
oscillation range adjustment. (For the procedures, refer to pages
5-1 to 5-2)
Result
YES Remove the cause of the circuit breaker operation, and press the
circuit breaker.
NO Check 24V of the copier.
YES Check the wiring to the stapler unit oscillation motor. If it is
normal, replace the stapler unit oscillation motor.
YES Stapler unit oscillation motor home position switch (MS4)
Replace the sorter controller PWB, and perform the bin paper
sensor sensitivity adjustment, the guide bar motor oscillation
range adjustment, and the stapler oscillation motor oscillation
range adjustment. (For the procedures, refer to pages 5-1 to 5-2.)
Result
NO Connect properly.
YES Remove the cause of the circuit breaker operation, and press the
circuit breaker.
NO Check the 24V power of the copier.
NO Check the wiring to the bin shift motor. If it is normal, replace the
bin shift motor.
NO Replace the sorter controller PWB, and perform the bin paper
sensor sensitivity adjustment, the guide bar motor oscillation
range adjustment, and the stapler oscillation motor oscillation
range adjustment. (For the procedures, refer to pages 5-1 to 5-2.)
Result
NO Start copying in a mode other than the non-sort mode with the
bin in the home position to check that the operation is performed
normally or not.
NO Properly connect the cable.
YES Replace the operation PWB.
