012-280 (A-Finisher) Eject Home Sensor OFF Fail

BSD-ON:12.6
In the Eject Motor's initializing operation and ejecting operation, the Eject Motor had rotated
forward for a time corresponding to a specified qty of pulses since the Eject Home Sensor was
On, and then the motor stopped, but then the Eject Home Sensor was not detected turning Off.
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.
Enter Component Control [012-252]. Block and unblock the Eject Home Sensor with a piece of
paper. The display changes.
Y N
Check the connections of P/J8700 and P/J8725.
connected.
Y N
Connect P/J8700 and P/J8725
Check for an open or short circuit between J8700 and J8725. The
J8700 and J8725 are OK.
Y N
Repair the open or short circuit.
Measure the voltage between Finisher PWB J8700-9 (+) 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 J8700-8 (+) and GND (-). Block and unblock
the Eject Home Sensor with a piece of paper. The voltage changes.
Y N
Replace the Eject Home Sensor
Check the wires and connectors for an intermittent open or short circuit. If the problem
continues, replace the Finisher PWB
Enter [012-054] and [012-056] alternately. The Eject Motor rotates.

Measure the voltage between Finisher PWB J8706-13 (+) and GND (-), and between
J8706-15 (+) and GND (-). Each voltage is approx. +24VDC.
