12-740 Ejector Fault RAP
12-740 The machine has detected a fault with the ejector.
Procedure
WARNING
Switch off the electricity to the machine. Disconnect the power cord from the customer
supply while performing tasks that do not need electricity. Electricity can cause death or
injury. Moving parts can cause injury.
NOTE: The finisher door switch must be closed to supply +24V to the motors.
Refer to Wiring Diagram 15 and Wiring Diagram 16. Perform the following:
1. Switch off the machine, then switch on the machine.
2. Remove all documents from the finisher.
3. Check for damage or obstructions that would prevent the ejector, PL 12.40 Item 16 from
operating correctly.
4. Enter dC330 code 12-835. Check the ejector encoder sensor (Q12-835), PL 12.25 Item 3.
5. Check the wiring between the ejector encoder sensor and J13 on the Finisher PWB. If
necessary, install a new ejector encoder sensor, PL 12.25 Item 3.
6. Enter dC330 code 12-830. Check the ejector home sensor (12-830), PL 12.20 Item 7.
7. Check the wiring between the ejector home sensor and J7 on the Finisher PWB. If neces-
sary, install a new ejector home sensor, PL 12.20 Item 7.
8. Enter dC330 code 12-500. Check that the ejector motor (MOT12-500), PL 12.40 Item 1
runs and drives the ejector belt, PL 12.40 Item 7.
9. Check the wiring between the ejector motor and J6 on the Finisher PWB.
10. Check that the finisher PWB DIP switch settings are correct. Refer to the 12A Finisher
PWB DIP Switch Settings RAP.
11. If necessary, install new components:
• Ejector motor, PL 12.40 Item 1.
• Ejector assembly, PL 12.40 Item 16.
• Finisher PWB, PL 12.10 Item 8.

12-750 Stapler Fault RAP
12-750 The machine has detected a fault with the stapler.
Procedure
Switch off the electricity to the machine. Disconnect the power cord from the customer
supply while performing tasks that do not need electricity. Electricity can cause death or
injury. Moving parts can cause injury.
NOTE: The finisher door switch must be closed to supply +24V to the motors.
Refer to Wiring Diagram 15 and Wiring Diagram 16. Perform the following:
1. Switch off the machine, then switch on the machine.
2. Check the following:
• The staple refill, PL 12.35 Item 5 has staples in it and is correctly installed.
• The leading staples in the staple head have been primed, Figure 1.
• Check that the sheets of staples in the cartridge are feeding one at a time. If staple
sheets overlap, they will jam in the cartridge. If necessary, install a new stapler car-
tridge, PL 12.35 Item 4.
NOTE: The term "primed" refers to 2 staples at the front of the cartridge, that have been
pre-formed automatically by the action of the stapler, refer to Figure 1.
NOTE: The stapler sensors are all integral to the stapler assembly. They cannot be
replaced.
3. Remove the stapler cartridge, PL 12.35 Item 4. Enter dC330 code 12-700. Check that the
stapler cycles once.
4. Check the wiring between the stapler motor (MOT12-700) and J10 on the Finisher PWB.
5. Enter dC330 code 12-865. Check the paper detector sensor (Q12-865), PL 12.20 Item
25.
6. Check the wiring between the paper detector sensor and J11 on the Finisher PWB. If nec-
essary, install a new paper detector sensor, PL 12.20 Item 25.
NOTE: If the stapler does not detect staples in the primed position, the staple head cycles
a number of times to prime the staple head. This occurs when the finisher interlock is
made.
7. Perform the following:
a. Remove the stapler cartridge. Remove the staple refill from the cartridge. Slide out
the bottom sheet of staples from the refill, to expose a fresh sheet of staples on the
bottom of the stack. Install the staple refill into the cartridge. Ensure the forming plate
is fully closed, Figure 1.
b. Install the staple cartridge and close the door. The stapler will now cycle a few times
to feed and prime the new sheet of staples.
c. Open the door and remove the staple cartridge.
d. Examine the sheet of staples that have been fed to the staple forming part of the sta-
pler, by opening the forming plate, Figure 2. Check that the first two staples have
been partially formed.
