012-291 (A-Finisher) Stapler Fail
BSD-ON:CH15.5
Within a specified time after the Staple Motor started rotating in reverse direction, the Staple
Head Home Sensor was never detected turning On.
Initial Actions
• Check that the Staple Assembly and the Cartridge are properly installed, not broken and
include no foreign objects.
• Power Off/ON.
Procedure
Enter Component Control [012-046] and [012-047] alternately. The Staple Motor rotates.
Y N
Check the connections of P/J8705 and P/J8735. P/J8705 and P/J8735 are securely
connected.
Y N
Connect P/J8705 and P/J8735 securely.
Check for an open or short circuit between J8705 and J8735. The
J8705 and J8735 are OK.
Y N
Repair the open wire or short circuit.
Enter [012-046] and [012-047] alternately. Measure the voltages between Finisher PWB
J8705-3, 4, 5, 6 (+) and GND (-). Each voltage changes.
Y N
Check the wires and connectors for an intermittent open or short circuit. If the prob-
lem continues, replace the Finisher PWB (PL 22.7)
Replace the Staple Assembly (PL 22.4).
Enter [012-046] and [012-047] alternately. The display changes.
Y N
Check the connections of P/J8701 and P/J8731. P/J8701 and P/J8731 are securely
connected.
Y N
Connect P/J8701 and P/J8731 securely.
Check for an open or short circuit between J8701 and J8731. The
J8701 and J8731 are OK.
Y N
Repair the open or short circuit.
Measure the voltage between Finisher PWB J8701-4 (+) and GND (-). The voltage is
approx. +5VDC.
Y N
Go to Wirenet 7.2.36 A-Finisher +5VDC and check the +5VDC circuit.

Measure the voltage between Finisher PWB P/J8701-5 (+) and GND (-). Enter [012-046]
and [012-047] alternately. The voltage changes.
Y N
Replace the Staple Assembly (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).
