012-221 (A-Finisher) Front Tamper Home Sensor ON Fail

BSD-ON:12.4
During the moving of the Front Tamper, when the Front Tamper Home Sensor was Off, to the
home position, the Front Tamper Home Sensor did not detected turning On within a specified
time after the Front Tamper started moving.
Initial Actions
• Check the Front Tamper Home Sensor is properly installed and has no foreign object and
that the actuator is not broken.
• Power Off/ON.
Procedure
Check the Front Tamper for any foreign object, deformation and binding that prevents it from
moving. The Front Tamper is defects and binding.
Y N
Repair the deformation and remove the foreign object(s) and the binding.
Check the drive mechanism to the Front Tamper for a deformed or broken part and not-seated
gears. The drive mechanism is free from defects and the gears seat properly.
Y N
Repair the Front Tamper mechanism.
Run DC330[012-220].
Enter Component Control [012-220]. Move the Front Tamper by hand to block and unblock the
Front Tamper Home Sensor. The display changes.

Y N
Connect P/J8700 and P/J8724
Check for an open or short circuit between J8700 and J8724. The
J8700 and J8724 are OK.
Y N
Repair the open wire or short circuit.
Measure the voltage between Finisher PWB J8700-6 (+) and GND (-). The

Y N
Go to Wirenet A-Finisher +5VDC and check the +5VDC circuit.
Measure the voltage between Finisher PWB J8700-5 (+) and GND (-). Move the Front
Tamper by hand to block and unblock the Front Tamper Home Sensor. The
changes.
Y N
Replace the Front Tamper Home Sensor
Check the wires and connectors for an intermittent open or short circuit. If the problem
continues, replace the Finisher PWB

Repair the open or short circuit.
Measure the voltage between Finisher PWB J8710-5 (+) and GND (-), and between
