024-976 (A-Finisher) Staple NG
BSD-ON:CH15.5
As Staple Head Home Sensor On was not detected within 450msec after the start of the oper-
ation of closing the Stapler Head, the reverse rotation started. After that, Staple Head Home
Sensor On was detected.
Initial Actions
• Check that the Top Cover and the Front Cover can be opened and closed.
• Check that the Staple Assembly and the Cartridge are properly installed, not broken and
include no foreign objects.
• Power Off/On.
Procedure
Check for remaining paper and foreign objects on the Compile Tray. The Compile Tray is
free of paper and/or foreign objects.
Y N
Remove the remaining paper and/or foreign object(s).
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 or short circuit.
Measure the voltages between J8705-3 to 6 (+) on the Finisher PWB and GND (-). Enter
[012-046] and [012-047] alternately. Each voltage changes.
Y N
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

A B
Measure the voltage between J8701-4 (+) 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 J8701-5 (+) on the Finisher PWB 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).
Check the wires and connectors for an intermittent open or short circuit. If the problem contin-
