Status Indicator RAPs
Initial Issue
012-224 (Integrated Finisher) Rear Tamper Home Sensor
OFF Fail RAP
BSD-ON:
BSD 12.4 - Integrated Finisher Tamping and Offset
•
At the end of the operation of trying to turn Off the Rear Tamper Home Sensor that was
On, the Rear Tamper Home Sensor was not detected being Off.
•
The Rear Tamper Home Sensor should have turned Off and then the Rear Tamper Motor
stopped, but the Rear Tamper Home Sensor was On.
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 in normal condition, not deformed or broken and with no
not-seated gears.
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 of 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 or short circuit between
P/J8700
and
P/J8726
. The wires between
P/J8700
and
P/J8726
are OK.
Y
N
Repair the open wire 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 wire or short circuit between
P/J8710
,
J8737A
and
J8737B
. The
wire 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 (-). The 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
).
Repair 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
).
