Procedure
Open the FINISHER FRONT COVER. Turn the
STAPLE HEAD ASSEMBLY manually.
Does the STAPLE HEAD move smoothly without any load?
Y
N
Remove the cause of STAPLE HEAD not moving, such as
rail breakage, drag, and gnawed gear.
Cheat the FRONT COVER INTERLOCK SWITCH.
Enter and run
DC330
[012-224].
Turn On/Off the STAPLE MOVE SENSOR with paper, etc.
Is the display switched between H and L?
Y
N
Repair the STAPLE MOVE SENSOR using the Generic
Permeable Sensor Failure FIP.
Execute
DC330
[012-081] (FRONT direction) or
DC330
[012-
083] (REAR direction).
Was the STAPLE MOVE MOTOR activated?
Y
N
Is +24 VDC measured between the FINISHER PWB J847-
3 (+) 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 J847 and the
STAPLER MOVE MOTOR J888 for an open circuit or
poor contact. If no problems are found, replace the
STAPLER MOVE MOTOR (PL15.9) and the FINISHER
PWB (PL15.13) in sequence.
Replace the FINISHER PWB. (PL15.13)
