12-537 RAP
Control Logic does not detect the signal Staple Head Home (L) within 450msec since the start
of Staple Head Close operation.
Initial Actions
Refer to BSD 12.13 for the following procedure:
• Ensure that connector P/J1092 is seated correctly to the Stapler Assembly, that connec-
tor P/J1044 is seated correctly to the Finisher PWB and that there are no obvious
crimped or broken wires on either connector.
• Check for staple jams.
Procedure
Remove the Stapler Cover Assembly ( REP 15.3.3 ). Remove the Staple Cartridge. Push the
Staple Assembly toward the rear of the Finisher until the semicircular cam on the front of the
assembly is facing forward. Manually rotate the cam in a clockwise direction until the flat por-
tion of the cam is facing up. Enter dC330 012-273 Staple Ready Sensor.
The display indi-
cates High.
Y
N
Disconnect P/J1092 from the Stapler. The display indicates High.
Y N
Go to Flag 2 on BSD 12.13. Check the wire for a short circuit to GND. If the wire is
good, replace the Finisher PWB ( PL 18.4 ).
Replace the Stapler Assembly ( PL 18.17 ).
Rotate the cam in a clockwise direction until the flat portion of the cam is facing down. The
display changes to Low.
Y
N
Disconnect P/J1092 from the Stapler. +5 VDC is measured between J1092-9 and
GND.
Y
N
Go to Flag 2 on BSD 12.13. Check the wire for an open circuit. If the wire is good,
replace the Finisher PWB ( PL 18.4 ).
Go to Flag 7 on BSD 12.13. Check the wires for an open circuit or short circuit to GND. If
the wires are good, replace the Stapler Assembly ( PL 18.17 ).
Replace the Stapler Assembly ( PL 18.17 ). If the problem continues, replace the Finisher PWB
( PL 18.4 ).
12-570 RAP
This fault is declared if one of the following occur:
•
Stacker Full (H) is detected during the Stacker Tray height adjustment (descending).
• Stacker Full (Mixed Size) (H) is detected during the Stacker Tray height adjustment
(descending) while ejecting mixed-size sets.
• A mixed-size set is ejected after Stacker Full (Mixed Size) (H) is detected.
Initial Actions
Refer to BSD 12.15 for the following procedure.
Ensure that the Stacker Tray is empty. If the fault is declared with an empty Stacker Tray, pro-
ceed with this RAP.
Procedure
Enter dC330 012-253 Stacker Paper Sensor. Press Start . Manually actuate the Stacker Paper
Sensor. The display changes from Low to High to Low as the actuator moves in and out
of the sensor.
Y
N
The display is always Low.
Y
N
Disconnect P/J1069 . There is +5 VDC from J1069-1 to J1069-3.
Y N
+5 VDC is measured from
P/J1038 -1 to P/J1038 -3.
Y N
+5 VDC is measured from
P/J1026 -3 to P/J1026 -2.
Y N
Go to Flag 17 on BSD 12.1. Check the +5VDC wiring for an open cir-
cuit.
Replace the Finisher PWB ( PL 18.4 ).
Go to Flag 8 on BSD 12.15. Check the harness for an open circuit.
There is +5 VDC from J1069-2 to J1069-3.
Y
N
Go to Flag 9 on BSD 12.15. Check the harness for an open circuit. If the wire is
good, replace the Finisher PWB ( PL 18.4 )
Replace the Stacker Paper Sensor ( PL 18.27 ). If the problem continues, replace the
Finisher PWB ( PL 18.4 ).
Disconnect P/J1069 . The display is High.
Y N
Go to Flag 9 on BSD 12.15. Check the wire for a short circuit to GND. If the wire is
good, replace the Finisher PWB ( PL 18.4 )
Replace the Stacker Paper Sensor ( PL 18.27 ).
Press the C button. Enter dC330 012-210 Stacker Full Sensor. Press Start . The display is
Low.
