Initial Issue
Status Indicator RAPs
012-284 (Integrated Finisher) Set Clamp Home Sensor OFF
Fail RAP
BSD-ON:
BSD 12.7 - Integrated Finisher Set Eject (2 of 2)
In the initialize operations each at Power On, when Interlock closed and at the start of a job,
and in the Set Clamp Motor’s ejecting operation, the Set Clamp Home Sensor was not
detected turning Off within a specified time after the start of the Set Clamp Motor operation.
Initial Actions
•
Check the Set Clamp Home Sensor is properly installed and has no foreign object and
that the actuator is not broken.
•
Power Off/ON.
Procedure
Check the Set Clamp mechanism for a deformed or broken part and not-seated belts. The
mechanism is free from defects and belt damage.
Y
N
Repair the Set CLamp mechanism.
Enter
Component Control
[012-251]. Rotate the Set Clamp Shaft by hand to block and unblock
the Set Clamp Home Sensor. The display changes.
Y
N
Check the connections of
P/J8707
,
P/J8742B
,
P/J8742A
and
P/J8723
.
P/J8707
,
P/
J8742B
,
P/J8742A
and
P/J8723
are securely connected.
Y
N
Connect
P/J8707
,
P/J8742B
,
P/J8742A
and
P/J8723
securely.
Check for an open or short circuit between
P/J8707
and
J8742B
, and between
J8742A
and
P/J8723
. The wires between
P/J8707
and
J8742B
and between
J8742A
and
P/
J8723
are OK.
Y
N
Repair the open or short circuit.
Measure the voltage between Finisher PWB
P/J8707
-9 (+) and GND (-). The voltage is
approx. +5VDC.
Y
N
Go to
Integrated Finisher Wirenets
and check the +5VDC circuit.
Measure the voltage between Finisher PWB
P/J8707
-8 (+) and GND (-). Rotate the Set
Clamp Shaft by hand to block and unblock the acceptance surface of the Set Clamp
Home Sensor. The voltage changes normally.
Y
N
Replace the Set Clamp Home Sensor (
PL 22.4
).
Check the wires and connectors for an intermittent open or short circuit. If the problem
continues, replace the Finisher PWB (
PL 22.7
).
Enter [012-017]. The Set Clamp Motor rotates.
Y
N
Check the connections of
P/J8708
and
P/J8740
.
P/J8708
and
P/J8740
are securely
connected.
Y
N
Connect
P/J8708
and
P/J8740
securely.
Check for an open or short circuit between
P/J8708
and
P/J8740
. The wires between
P/J8708
and
P/J8740
are OK.
Y
N
Repair the open or short circuit.
Measure the voltage between Finisher PWB
P/J8708
-9 (+) and GND (-), and between
P/
J8708
-11 (+) and GND (-). Each voltage is approx. +24VDC.
Y
N
Go to
Integrated Finisher Wirenets
and check the +24VDC circuit. If the problem
continues, replace the Finisher PWB (
PL 22.7
).
Replace the Set Clamp Motor (
PL 22.9
). If the problem continues, replace the Finisher
PWB (
PL 22.7
).
Check the wires and connectors for an intermittent open or short circuit. If the problem contin-
ues, replace the Finisher PWB (
PL 22.7
).
