012-904 COMPILER PAPER SENSOR STATIC JAM
Description
In either one of the following cases:
• The COMPILER PAPER SENSOR continues to detect
paper when the paper was output automatically due to the
power On initialization.
• The COMPILER PAPER SENSOR detected paper with no
history of paper output to the COMPILER TRAY when all
the INTERLOCK were closed.
BSD on : CH11.6 CH11.11B
Check Items
• Check that the power voltage at the customer site does not
drop.
• The Actuator for return failure
• Run the following DC330 INPUT CHECK to check the
circuit of the Sensor.
DC330
[012-102] COMPILER PAPER SENSOR
• FINISHER PWB failure (PL15.13)
012-910 STAPLE FEED READY FAILURE
Description
In either one of the following cases:
• At the staple preparation operation at initialization, the
STAPLE READY SENSOR does not go to READY (L)
status after 13 times of stapling operation.
• The STAPLER READY SENSOR is turned Off (H) just
before the STAPLE.
BSD on : CH11.8 CH11.11B
Procedure
Remove the STAPLE HEAD ASSY with a connector
connected. Execute
DC330
[012-209].
Manually turn On and Off the STAPLE READY SENSOR.
Is the display switched between H and L?
Y
N
Is +5 VDC measured between the STAPLE HEAD ASSY
J886-5 (+) and GND (-)?
Y
N
Is +5 VDC measured between the FINISHER PWB
J852-1 (+) and GND (-)?
Y
N
Is +24 VDC measured between the FINISHER
PWB J844-2 (+) and GND (-)?
Y
N
Check the +24 VDC circuit to the
FINISHER PWB J844-2 by referring to the
BSD CH11.1.
Replace the FINISHER PWB. (PL15.13)
Check the wire between the FINISHER PWB J852-1
and the STAPLE HEAD ASSY J886-5 for an open
circuit or poor contact.
Pull out the cartridge.
Is +5 VDC measured between the FINISHER PWB J852-3
(+) and GND (-)?
Y
N
Turn Off the power.
Pull out the J852 on the FINISHER PWB.
Turn On the power.
Is +5 VDC measured between the FINISHER PWB
P852-3 (+) and GND (-)?
Y
N
Replace the FINISHER PWB. (PL15.13)
Check the circuit between the J852-3 and the
STAPLE HEAD ASSY J886-3 for short circuit.
Load the cartridge.
Is 0 VDC measured between the FINISHER PWB J852-3
(+) and GND (-)?
Y
N
Is 0 VDC measured between the STAPLE HEAD
ASSY J886-3 (+) and GND (-)?
Y
N
Replace the STAPLE HEAD ASSY. (PL15.9)
Check the wire between the STAPLE HEAD ASSY
J886-3 and the FINISHER PWB J852-3 for an open
circuit or poor contact.
Replace the FINISHER PWB. (PL15.13)
Restore the STAPLE HEAD to the original status and cheat the
FRONT INTERLOCK SWITCH.
Run
DC330
[012-020] (CLOSE).
Does the STAPLE MOTOR operate?
Y
N
With
DC330
[012-020] running
Is +24 VDC measured between the FINISHER PWB J847-
7 (+) and GND (-)?
Though it is possible to run the following Diag on
the machine not installed with the Finisher, an error
will be displayed.
