012-284 Set Clamp Home Sensor Off Failure RAP

BSD-ON:12.22/12.23
After the Set Clamp completed operation, the Set Clamp Home Sensor did not turn Off within
the specified time.
Initial Actions
• Power OFF/ON
• Remove foreign substances in the Eject Clamp mechanism.
Procedure
Manually operate the Eject Clamp mechanism. The

Connect J8871 and P/J8988.
Check the wire between J8871 and J8988 for an open circuit or a short circuit (BSD
12.23). The wire between J8871 and J8988 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 P8988-12 (+) and GND (-) (BSD 12.23).
The voltage is approx. +5VDC.
