Initial Issue
012-221 (Integrated Finisher) Front Tamper Home Sensor
ON Fail RAP
BSD-ON:
BSD 12.4 - Integrated Finisher Tamping and Offset
During the moving of the Front Tamper, when the Front Tamper Home Sensor was Off, to the
home position, the Front Tamper Home Sensor did not detected turning On within a specified
time after the Front Tamper started moving.
Initial Actions
•
Check the Front Tamper Home Sensor is properly installed and has no foreign object and
that the actuator is not broken.
•
Power Off/ON.
Procedure
Check the Front Tamper for any foreign object, deformation and binding that prevents it from
moving. The Front Tamper is defects and binding.
Y
N
Repair the deformation and remove the foreign object(s) and the binding.
Check the drive mechanism to the Front Tamper for a deformed or broken part and not-seated
gears. The drive mechanism is free from defects and the gears seat properly.
Y
N
Repair the Front Tamper mechanism.
Enter
Component Control
[012-220]. Move the Front Tamper by hand to block and unblock the
Front Tamper Home Sensor. The display changes.
Y
N
Check the connections of
P/J8700
and
P/J8724
.
P/J8700
and
P/J8724
are securely
connected.
Y
N
Connect
P/J8700
and
P/J8724
securely.
Check for an open or short circuit between
P/J8700
and
P/J8724
. The wires between
P/J8700
and
P/J8724
are OK.
Y
N
Repair the open wire or short circuit.
Measure the voltage between Finisher PWB
P/J8700
-6 (+) 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
-5 (+) and GND (-). Move the Front
Tamper by hand to block and unblock the Front Tamper Home Sensor. The voltage
changes.
Y
N
Replace the Front Tamper Home Sensor (
PL 22.10
).
Check the wires and connectors for an intermittent open or short circuit. If the problem
continues, replace the Finisher PWB (
PL 22.7
).
Enter [012-020] and [012-023] alternately. The Front Tamper Motor rotates.
Y
N
Check the connections of
P/J8710
,
J8738A
and
P/J8738B
.
P/J8710
,
J8738A
and
J8738B
are securely connected.
Y
N
Connect
P/J8710
,
J8738A
and
P/J8738B
securely.
Check for an open or short circuit between
P/J8710
,
J8738A
and
J8738B
. The wires
between are OK.
Y
N
Repair the open or short circuit.
Measure the voltage between Finisher PWB
P/J8710
-5 (+) and GND (-), and between
P/
J8710
-7 (+) 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
).
Replace the Front Tamper Motor (
PL 22.10
). If the problem continues, replace the Fin-
isher 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
).
