BSD 12.4 - Integrated Finisher Tamping and Offset
•
At the end of the operation to turn Off the Front Tamper Home Sensor that was On, the
Front Tamper Home Sensor was not detected being Off.
•
The Front Tamper Home Sensor should have turned Off and then the Front Tamper Motor
stopped, but the Front Tamper Home Sensor was On.
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 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 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 drive 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 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 wire or short circuit between
P/J8710
,
J8738A
and
J8738B
. The
wire between
P/J8710
,
J8738A
and
J8738B
are OK.
Y
N
Repair the open wire or short circuit.
Measure the voltage between Finisher PWB
P/J8710
-5 (+) and GND (-), and between
P/
J8710
-7 (+) 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 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
).
