Status Indicator RAPs
Initial Issue
012-263 (Integrated Finisher) Rear Tamper Home Sensor
ON Fail RAP
BSD-ON:
BSD 12.4 - Integrated Finisher Tamping and Offset
During the moving of the Rear Tamper from when the Rear Tamper Home Sensor was Off to
the home position, the Rear Tamper Home Sensor was not detected turning On within a speci-
fied time after the Rear Tamper started moving.
Initial Actions
•
Check the Rear Tamper Home Sensor is properly installed and has no foreign object and
that the actuator is not broken.
•
Power Off/ON.
Procedure
Check the Rear Tamper for any foreign object, deformation and binding that prevents it from
moving. The Rear Tamper is free from defects and binding.
Y
N
Repair the deformation and remove the foreign object(s) and the binding.
Check the drive mechanism to the Rear Tamper for a deformed or broken part and not-seated
gears. The drive mechanism is free from defects and gears seat properly.
Y
N
Repair the Rear Tamper drive mechanism.
Enter
Component Control
[012-221]. Move the Rear Tamper by hand to block and unblock the
Rear Tamper Home Sensor. The display changes.
Y
N
Check the connections of
P/J8700
and
P/J8726
.
P/J8700
and
P/J8726
are securely
connected.
Y
N
Connect
P/J8700
and
P/J8726
securely.
Check for an open wire or short circuit between
P/J8700
and
P/J8726
. The wire
between
P/J8700
and
P/J8726
are OK.
Y
N
Repair the open or short circuit.
Measure the voltage between Finisher PWB
P/J8700
-12 (+) 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/J8700
-11 (+) and GND (-). Move the Rear
Tamper by hand to block and unblock the Rear Tamper Home Sensor. The voltage
changes.
Y
N
Replace the Rear Tamper Home Sensor (
PL 22.9
).
Check the wires and connectors for an intermittent open or short circuit. If the problem
continues, replace the Finisher PWB (
PL 22.7
).
Enter [012-026] and [012-029] alternately. The Rear Tamper Motor rotates.
Y
N
Check the connections of
P/J8710
,
J8737A
and
P/J8738B
.
P/J8710
,
J8737A
and
P/
J8738B
are securely connected.
Y
N
Connect
P/J8710
,
J8737A
and
P/J8738B
securely.
Check for an open or short circuit between
P/J8710
,
J8737A
and
J8737B
. The wires
between
P/J8710
,
J8737A
and
J8737B
are OK.
Y
N
Repair the open or short circuit.
Measure the voltage between Finisher PWB
P/J8710
-1 (+) and GND (-), and between
P/
J8710
-3 (+) 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 Rear Tamper Motor (
PL 22.10
). 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
).
