012-260 Eject Clamp Home Sensor ON RAP
BSD-ON:12.7
After the Eject Clamp started ascending, the Eject Clamp Home Sensor did not turn On within
500ms.
Initial Actions
• Power Off/On
• Remove foreign substances in the Eject Clamp mechanism.
Procedure
Manually operate the Eject Clamp mechanism. The
smoothly.
Y N
Replace the parts that are interfering with operation.
Execute Component Control [012-250 Eject Clamp Home Sensor]. Actuate the Eject Clamp
Home Sensor with paper. The display changes.
Y N
Check the connections of P/J8803 and P/J8849. P/J8803 and
nected correctly.
Y N
Connect P/J8803 and P/J8849.
Check the wire between J8803 and J8849 for an open circuit or a short circuit (BSD 12.7
Flag 3/Flag 4). The wire between J8803 and J8849 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 P8849-6 (+) and GND (-) (BSD 12.7 Flag
4). The voltage is approx. +5VDC.
Y N
Replace the Finisher PWB (PL 17.12).
Measure the voltage between the Finisher PWB P8849-5 (+) and GND (-) (BSD 12.7 Flag
3).Actuate the Eject Clamp Home Sensor with paper. The voltage changes.
Y N
Replace the Eject Clamp Home Sensor (PL 17.7).
Replace the Finisher PWB (PL 17.12).
Alternately execute Component Control [012-081 Eject Motor FORWARD ON] and Component
Control [012-082 Eject Motor REVERSE ON]. The Eject Motor starts up.
Y N
Check the connections of P/J8801 and P/J8846. P/J8801 and
nected correctly.
Y N
Connect P/J8801 and P/J8846.

A B
Check the wire between J8801 and J8846 for an open circuit or a short circuit (BSD 12.7
Flag 5). The wire between J8801 and J8846 is conducting without an open circuit or
a short circuit.
Y N
Repair the open circuit or short circuit.
Measure the resistance of the Eject Motor between J8801-2/5 (COM) and each point of
J8801-1/3/4/6 (BSD 12.7 Flag 5). The resistance is approx. 2Ohm.
Y N
Replace the Eject Motor (PL 17.7).
Measure the voltage between the Finisher PWB P8848-6 (+) and GND (-), and between
P8846-12 (+) and GND (-) (BSD 12.7 Flag 5). The voltage is approx. +24VDC.
Y N
Replace the Finisher PWB (PL 17.12).
Replace the Eject Motor (PL 17.7). If the problem persists, replace the Finisher PWB (PL
17.12).
Replace the Finisher PWB (PL 17.12).
