012-283 (A-Finisher) Set Clamp Home Sensor ON Fail

BSD-ON:12.7
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,
J8742B, P/J8742A and P/J8723 are securely connected.
Y N
Connect P/J8707, P/J8742B,
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 A-Finisher +5VDC 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
changes.
Y N
Replace the Set Clamp Home Sensor
Check the wires and connectors for an intermittent open or short circuit. If the problem
continues, replace the Finisher PWB
Enter [012-017]. The Set Clamp Motor rotates.
Y N
Check the connections of P/J8706 and P/J8740.

Connect P/J8706
Check for an open or short circuit between J8706 and J8740. The
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 A-Finisher +24VDC and check the +24VDC circuit. If the problem con-
