012-314 Eject Clamp Home Sensor On Failure RAP
BSD-ON:12.7
The Eject Clamp Home Sensor did not turn On within a specific time.
Initial Actions
• Power Off/On
• Remove foreign substances in the Eject Clamp mechanism.
Procedure
Manually operate the Eject Clamp mechanism. The Eject Clamp mechanism moves
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. The display changes.
Y
N
Check the connections of J8803 and P/J8849. J8803 and P/J8849 are connected cor-
rectly.
Y
N
Connect P/J8802 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 P/J8846 are con-
nected correctly.
Y
N
Connect P/J8801 and P/J8846.
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 P8846-6 (+) 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).
Execute Component Control [012-086 Set Clamp Clutch ON]. The Set Clamp Clutch starts
operating.
Y
N
Check the connections of P/J8822 and P/J8848. P/J8822 and P/J8848 are con-
nected correctly.
Y
N
Connect P/J8822 and P/J8848.
Check the wire between J8822 and J8848 for an open circuit or a short circuit (BSD 12.7
Flag 6). The wire between J8822 and J8848 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 P8848-A10 (+) and GND (-). The volt-
age is approx. +24VDC.
Y
N
Replace the Set Clamp Clutch (PL 17.5). If the problem persists, 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).
