012-283 (A-Finisher) Set Clamp Home Sensor ON Fail
BSD-ON:CH15.7
In the initialize operations each at Power On, when Interlock closed and at the start of a job,
and in the Set Clamp Motor’s ejecting operation, the Set Clamp Home Sensor was not
detected turning On within a specified time after the start of the Set Clamp Motor operation.
Initial Actions
• Check the Set Clamp Home Sensor is properly installed and has no foreign object and
that the actuator is not broken.
• Power Off/ON.
Procedure
Check the Set Clamp mechanism for a deformed or broken part and not-seated belts. The
mechanism is free from defects and belt damage.
Y
N
Repair the Set Clamp mechanism.
Enter Component Control [012-251]. Rotate the Set Clamp Shaft by hand to block and unblock
the Set Clamp Home Sensor. The display changes.
Y
N
Check the connections of P/J8707, P/J8742B, P/J8742A and P/J8723. P/J8707, P/
J8742B, P/J8742A and P/J8723 are securely connected.
Y
N
Connect P/J8707, P/J8742B, P/J8742A and P/J8723 securely.
Check for an open or short circuit between J8707 and J8742B, and between J8742A and
J8723. The wires between J8707 and J8742B and between J8742A and J8723 are
OK.
Y
N
Repair the open or short circuit.
Measure the voltage between Finisher PWB J8707-9 (+) and GND (-). The voltage is
approx. +5VDC.
Y
N
Go to Wirenet 7.2.36 A-Fi5VDC and check the +5VDC circuit.
Measure the voltage between Finisher PWB J8707-8 (+) and GND (-). Rotate the Set
Clamp Shaft by hand to block and unblock the Set Clamp Home Sensor. The voltage
changes.
Y
N
Replace the Set Clamp Home Sensor (PL 22.4).
Check the wires and connectors for an intermittent open or short circuit. If the problem
continues, replace the Finisher PWB (PL 22.7).
Enter [012-017]. The Set Clamp Motor rotates.
Y
N
Check the connections of P/J8706 and P/J8740. P/J8706 and P/J8740 are securely
connected.
Y N
Connect P/J8706 and P/J8740 securely.
Check for an open or short circuit between J8706 and J8740. The wires between
J8706 and J8740 are OK.
Y
N
Repair the open or short circuit.
Measure the voltage between Finisher PWB J8706-9 (+) and GND (-), and between
J8706-11 (+) and GND (-). Each voltage is approx. +24VDC.
Y
N
Go to Wirenet 7.2.38 A-Fi24VDC and check the +24VDC circuit. If the prob-
lem continues, replace the Finisher PWB (PL 22.7).
Replace the Set Clamp Motor (PL 22.9). If the problem continues, replace the Finisher
PWB (PL 22.7).
Check the wires and connectors for an intermittent open or short circuit. If the problem contin-
ues, replace the Finisher PWB (PL 22.7).
