012-221 Front Tamper Home Sensor On Failure RAP

BSD-ON:12.18/12.19
After the Front Tamper started moving to the home position, the Front Tamper Home Sensor
did not turn On within 800ms.
Initial Actions
• Power OFF/ON
• Remove foreign substances in the Compiler Tray.
Procedure
Manually operate the Tamper mechanism. The Tamper mechanism moves smoothly.
Y N
Replace the parts that are interfering with operation.
Execute Component Control[012-220 Front Tamper Home Sensor]. Actuate the Front Tamper
Home Sensor with paper. The display changes. The display changes.
Y N
Check the connections of J8881 and J8984.

Y N
Connect J8881 and J8984.
Check the wire between J8881 and J8984 for an open circuit or a short circuit (BSD
12.19). The wire between J8881 and J8984 is conducting without an open circuit or
a short circuit.
Y N
Repair the open circuit or short circuit.
Measure the voltage between the Finisher PWB P8984-6 (+) and GND (-) (BSD 12.19).
The voltage is approx. +5VDC.
Y N
Replace the Finisher PWB (PL
Measure the voltage between the Finisher PWB P8984-5 (+) and GND (-) (BSD 12.19).
Actuate the Front Tamper Home Sensor with paper. The voltage changes.
Y N
Replace the Front Tamper Home Sensor
Replace the Finisher PWB (PL 23.16).
Alternately execute Component Control[012-020 Front Tamper Motor FRONT ON] and
ponent Control[012-023 Front Tamper Motor REAR ON]. The Front Tamper Motor starts up.
