B C
Check for an open or short circuit between J8707 and J8721. The
J8707 and J8721 are OK.
Y N
Repair the open or short circuit.
Measure the voltage between J8707-3 (+) on the Finisher PWB and GND (-). The volt-
age is approx. +5VDC.
Y N
Using Chapter 7 Wirenets, check the +5VDC circuit to J8707-3 on the Finisher PWB.
Measure the voltage between J8707-2 (+) on the Finisher PWB and GND (-). Rotate the
Stacker Stack Sensor 2 actuator by hand to block and unblock the sensor. The
changes.
Y N
Replace the Stacker Stack Sensor 2 (PL 22.8).
Check the wires and connectors for an intermittent open or short circuit. If the problem
continues, replace the Finisher PWB (PL 22.7).
Enter [012-060] and [012-061] alternately. The Stacker Motor rotates.
Y N
Check the connections of P/J8711 and P/J8736. P/J8711 and P/J8736 are securely
connected.
Y N
Connect P/J8711 and P/J8736 securely.
Check for an open or short circuit between J8711 and P8736. The
J8711 and P8736 are OK.
Y N
Repair the open or short circuit.
Enter [012-060], measure the voltage between J8711-1 (+) on the Finisher PWB and
GND (-). The 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).
Enter [012-061], measure the voltage between J8711-2 (+) on the Finisher PWB and
GND (-). The 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 Stacker Motor (PL 22.8).
Check the connections of the connectors between the Finisher and the IOT. The connectors
are securely connected.
Y N
Connect the connectors securely.
If the problem continues, replace the Finisher PWB (PL 22.7).

wires between 024-917 (A-Finisher) Stacker Tray Staple Set Over Count
BSD-ON:CH15.2, CH15.8
While sets of stapled sheets of paper are being ejected, the Staple Set Count for the Stacker
Tray exceeded 30.
Initial Actions
• Check that the Stack Height Sensor is properly installed, not broken and has no foreign
objects.
• Check Stacker Stack Sensors 1 and 2 are properly installed and free from foreign objects
voltage
and that their actuators are not broken.
• Power Off/On.
Procedure
Check for remaining paper and foreign objects on the Stacker Tray. The Stacker Tray is in
normal condition with no paper or foreign object left there.
Y N
Remove the remaining paper and/or foreign object(s).
Check the drive mechanism to the Stacker Tray for a deformed or broken part and not-seated
gears. The drive mechanism is free of defects and gears seat properly.
Y N
Repair the Stacker Tray mechanism.
wires between Enter Component Control [012-267]. Block and unblock the Stack Height Sensor with a piece
of paper. The display changes.
Y N
Check the connections of P/J8708 and P/J8727. P/J8708 and P/J8727 are securely
connected.
Y N
Connect P/J8708 and P/J8727.
Check for an open or short circuit between J8708 and J8727. The
J8708 and J8727 are OK.
Y N
Repair the open wire or short circuit.
Measure the voltage between J8708-3 (+) on the Finisher PWB and GND (-). The volt-
age is approx. +5VDC.
Y N
Go to Wirenet 7.2.36 A-Finisher +5VDC and check the +5VDC circuit.
Measure the voltage between J8708-2 (+) on the Finisher PWB and GND (-). Block and
unblock the Stack Height Sensor with a piece of paper. The voltage changes.
Y N
Replace the Stack Height Sensor (PL 22.10).
Check the wires and connectors for an intermittent open or short circuit. If the problem
continues, replace the Finisher PWB (PL 22.7).
