012-259 (A-Finisher) Eject Home Sensor ON Fail
BSD-ON:CH15.6
In the Eject Motor's initializing operation and ejecting operation, one of the following is met.
• With the Eject Home Sensor Off, the Eject Motor started rotating in reverse direction.
Within a specified time after that, the Eject Home Sensor was not detected turning On.
• With the Eject Home Sensor Off, the Eject Motor started rotating in reverse direction. The
Eject Home Sensor should have been detected turning On and then the Eject Motor
stopped, but then the Eject Home Sensor was not On.
Initial Actions
• Check the Eject Home Sensor is properly installed, not broken and has no foreign object.
• Power Off/ON.
Procedure
Check the Eject mechanism for a deformed or broken part and not-seated belts. The mecha-
nism is free from defects and belt damage.
Y N
Repair the mechanism.
Run DC330[012-252].
Enter Component Control [012-252]. Block and unblock the Eject Home Sensor. The display
changes.
Y N
Check the connections of P/J8700 and P/J8725. P/J8700 and P/J8725 are securely
connected.
Y N
Connect P/J8700 and P/J8725 securely.
Check for an open wire or short circuit between J8700 and J8725. The wire between
J8700 and J8725 is normally conductive with no open wire or short circuit.
Y N
Repair the open wire or short circuit.
Measure the voltage between Finisher PWB J8700-9 (+) 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 J8700-8 (+) and GND (-). Block and unblock
the Eject Home Sensor. The voltage changes
Y N
Replace the Eject Home 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).
Enter [012-054] and [012-056] alternately. The Eject Motor rotates.

Y N
Check the connections of P/J8706 and P/J8741. P/J8706 and P/J8741 are securely
connected.
Y N
Connect P/J8706 and P/J8741 securely.
Check for an open or short circuit between J8706 and J8741. The
J8706 and J8741 are OK.
Y N
Repair the open wire or short circuit.
Measure the voltage between Finisher PWB J8706-13 (+) and GND (-), and between
J8706-15 (+) and GND (-). Each voltage is approx. +24VDC.
Y N
Go to Wirenet 7.2.38 A-Finisher +24VDC and check the +24VDC circuit. If the prob-
lem continues, replace the Finisher PWB (PL 22.7).
Replace the Eject 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).
