012-224 Rear Tamper Home Sensor Off Failure RAP
BSD-ON:12.18/12.19
After the Rear Tamper started moving away from the home position, the Rear Tamper Home
Sensor did not turn Off within the specified time.
Initial Actions
• Power OFF/ON
• Remove foreign substances in the Compiler Tray.
Procedure
Manually operate the Tamper mechanism. The Tamper mechanism moves smoothly.
YN
Replace the parts that are interfering with operation.
Execute Component Control[012-221 Rear Tamper Home Sensor]. Actuate the Rear Tamper
Home Sensor with paper.
The display changes.
YN
Check the connections of J8882 and J8984. J8882 and J8984 are connected cor-
rectly.
YN
Connect J8882 and J8984.
Check the wire between J8882 and J8984 for an open circuit or a short circuit (BSD
12.19).
The wire between J8882 and J8984 is conducting without an open circuit or
a short circuit.
YN
Repair the open circuit or short circuit.
Measure the voltage between the Finisher PWB P8984-9 (+) and GND (-) (BSD 12.19).
The voltage is approx. +5VDC.
YN
Replace the Finisher PWB (PL 23.16).
Measure the voltage between the Finisher PWB P8984-8 (+) and GND (-) (BSD 12.19).
Actuate the Rear Tamper Home Sensor with paper. The voltage changes.
YN
Replace the Rear Tamper Home Sensor (PL 23.12).
Replace the Finisher PWB (PL 23.16).
Alternately execute Component Control[012-026 Rear Tamper Motor FRONT ON] and Compo-
nent Control[012-029 Rear Tamper Motor REAR ON]. The Rear Tamper Motor starts up.
YN
Check the connections of P/J8883 and J8984. P/J8883 and J8984 are connected
correctly.
YN
Connect P/J8883 and J8984.
Check the wire between J8883 and J8984 for an open circuit or a short circuit (BSD
12.18).
The wire between J8883 and J8984 is conducting without an open circuit or
a short circuit.
YN
Repair the open circuit or short circuit.
Measure the resistance of the Front Tamper Motor between J8984-19 and each point of
J8984-1/3/4/6 (BSD 12.18).
The resistance is approx. 750Ohm.
YN
Replace the Front Tamper Motor (PL 23.12).
Measure the voltage between the Finisher PWB J8984-19 and each point of J8984-1/3/4/
6 (BSD 12.18).
The voltage is approx. +24VDC.
YN
Replace the Finisher PWB (PL 23.16).
Replace the Front Tamper Motor (PL 23.12). If the problem persists, replace the Finisher
PWB (PL 23.16).
Replace the Finisher PWB (PL 23.16).
