N
Does the REAR TAMPER MOTOR operate (or is it going
to operate)?
Y
N
Is +24 VDC measured between the REAR TAMPER
MOTOR J878B-5 (+) and GND (-)?
Y
N
Is +24 VDC measured between the FINISHER
PWB J848-B2 (+) and GND (-)?
Y
N
Is +24 VDC measured between the
FINISHER PWB J844-4 (+) and GND (-)?
Y
N
Check the INTLK ON +24 VDC
circuit to the FINISHER PWB J844-4
by referring to the BSD CH11.1.
Replace the FINISHER PWB. (PL15.13)
Check the wire between the FINISHER PWB
J848-B2 and the REAR TAMPER MOTOR
J878B-5 for a short circuit, open circuit, or poor
contact.
Check the wire (x 6) between the FINISHER PWB
J848 and the REAR TAMPER MOTOR P/J878 for an
open circuit or poor contact.
If no problems are found, replace the REAR
TAMPER MOTOR. (PL15.10) If the problem
persists, replace the FINISHER PWB. (PL15.13)
Turn the power Off and check the tampering mechanism
for load or drive transmission failure (gear wear or
breakage).
Enter
DC330
[012-212] and turn it On.
Move the REAR TAMPER manually and turn the REAR
TAMPER HOME SENSOR On/Off.
Is the display switched between H and L?
Y
N
Check the REAR TAMPER HOME SENSOR using the
Generic Permeable Sensor Failure FIP.
Replace the FINISHER PWB. (PL15.13)
012-254 STACKER TRAY FAILURE
Description
In either one of the following cases:
• The STACK HEIGHT SENSOR did not detect that the tray
went down within 500ms after the STACKER TRAY had
begun lowering down at initialization.
• The STACK HEIGHT SENSOR did not detect that the tray
went up within 5sec after the STACKER TRAY had begun
lifting up.
BSD on : CH11.10A CH11.11B
Check Items
Check the STACK HEIGHT SENSOR Actuator for
disengagement, bending, and breakage.
Procedure
Enter
DC330
[012-201] and turn it On.
Manually turn the STACK HEIGHT SENSOR Actuator to turn
the STACK HEIGHT SENSOR On/Off.
Is the display switched between H and L?
Y
N
Check the STACK HEIGHT SENSOR using the Generic
Permeable Sensor Failure FIP.
Turn
DC330
[012-050] (UP) or [012-051] (DOWN) On.
Did the STACKER TRAY operate?
Y
N
Was the operating sound of the STACKER MOTOR
audible?
Y
N
With
DC330
[012-050] (UP) running
Is +24 VDC measured between the FINISHER PWB
J847-12 (+) and GND (-)?
Y
N
Is +24 VDC measured between the FINISHER
PWB J844-4 (+) and GND (-)?
Y
N
Check the INTLK ON +24 VDC circuit to
the FINISHER PWB J844-4 by referring to
the BSD CH11.1.
Replace the FINISHER PWB. (PL15.13)
With
DC330
[012-050] (UP) running
Is +24 VDC measured between the STACKER
MOTOR J889-1 (+) and GND (-)?
Y
N
Check the wire between the FINISHER PWB
J847-12 and the STACKER MOTOR J889-1 for
an open circuit or poor contact.
With
DC330
[012-050] (UP) running
Is +24 VDC measured between the STACKER
MOTOR J889-2 (+) and GND (-)?
Y
N
Replace the STACKER MOTOR. (PL15.11)
Check the wire between the FINISHER PWB J847-11
and the STACKER MOTOR J889-2 for an open
circuit or poor contact. If no problems are found,
replace the STACKER MOTOR (PL15.11) and
FINISHER PWB (PL15.13) in sequence.
Check the following:
• The STACKER MOTOR GEAR for wear and damage
• The STACKER TRAY for dragging and improper
installation
• The STACKER ELEVATOR BELT/RACK/GEAR for
wear and damage
Though it is possible to run the following Diag on
the machine not installed with the Finisher, an error
will be displayed.
