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.
YN
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.
YN
Check the connections of J8881 and J8984. J8881 and J8984 are connected cor-
rectly.
YN
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.
YN
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.
YN
Replace the Finisher PWB (PL 23.16).
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.
YN
Replace the Front Tamper Home Sensor (PL 23.12).
Replace the Finisher PWB (PL 23.16).
Alternately execute Component Control[012-020 Front Tamper Motor FRONT ON] and Com-
ponent Control[012-023 Front Tamper Motor REAR ON]. The Front Tamper Motor starts up.
YN
Check the connections of P/J8884 and J8984. P/J8884 and J8984 are connected
correctly.
YN
Connect P/J8884 and J8984.
Check the wire between J8884 and J8984 for an open circuit or a short circuit (BSD
12.18).
The wire between J8884 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 22.10). If the problem persists, replace the Finisher
PWB (PL 23.16).
Replace the Finisher PWB (PL 23.16).
