08-600 Duplex Jam 0 RAP
08-600 The lead edge of the document failed to actuate the feed sensor within the correct time.
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 main PWB has 4 test points, GND, +3.3V, +5V and +24V. The location of the test
points is shown on the Main PWB PJ location illustration.
NOTE: The right cover assembly interlock switch must be closed to supply +24V to the motors
and clutches.
Refer to Wiring Diagram 5 and Wiring Diagram 7. Perform the following:
1. Open the right hand cover. Remove all jammed paper.
2. Check the paper path for damage or obstructions.
3. Check that the feed sensor actuator, PL 8.15 Item 5 moves freely and is not damaged. If
necessary, install a new feed sensor actuator assembly, PL 8.15 Item 14.
4. Enter dC330 code 08-100. Check the feed sensor (Q08-100), PL 8.15 Item 8.
5. Check the wiring between the feed sensor and CN13 on the Main PWB. If necessary,
install a new feed sensor, PL 8.15 Item 8.
6. Enter dC330 code 04-100 to run the main BLDC motor.
7. While the main BLDC motor runs, stack the code 08-850 to energize the registration
clutch (CL08-850). Check that the registration roll, PL 4.15 Item 1 rotates.
8. Check the wiring between the registration clutch, PL 4.15 Item 4 and CN13 on the Main
PWB. Install new components as necessary, PL 4.15.
9. Clean the registration roll, PL 4.15 Item 1 and the registration roll idler, PL 4.15 Item 7.
Install new components as necessary.
10. If necessary, install a new main PWB, PL 1.10 Item 1.

08-610 Duplex Jam 1 RAP
08-610 The lead edge of the document failed to actuate the duplex jam 1 sensor within the cor-
rect time in reverse mode.
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 main PWB has 4 test points, GND, +3.3V, +5V and +24V. The location of the test
points is shown on the Main PWB PJ location illustration.
NOTE: The right cover assembly interlock switch must be closed to supply +24V to the motors
and clutches.
Refer to Wiring Diagram 3 and Wiring Diagram 7. Perform the following:
1. Open the right hand cover. Remove all jammed paper.
2. Unclip the duplex assembly, PL 7.30 Item 28. Check that the paper path is clear and not
damaged.
3. Check that the duplex jam 1 sensor actuator, PL 7.30 Item 20 moves freely and is not
damaged.
4. Enter dC330 code 08-700. Check the duplex jam 1 sensor (Q08-700), PL 7.30 Item 18.
5. Check the wiring between the duplex jam 1 sensor and CN25 on the Main PWB. If neces-
sary, install a new duplex jam 1 sensor, PL 7.30 Item 18.
6. Enter dC330 code 04-300, then code 04-310. Check that the duplex motor (MOT04-300),
PL 10.20 Item 2, runs in forward and reverse and drives the duplex roll, PL 10.15 Item 22.
7. Check the wiring between the duplex motor and CN12 on the Main PWB. Install new com-
ponents as necessary, PL 10.15 and PL 10.20.
8. Enter dC330 code 08-870. Check that the duplex gate solenoid (SOL08-870), PL 10.15
Item 4 energises and lowers the duplex gate, PL 10.15 Item 15.
9. Check the duplex gate for damage. If necessary, install a new duplex gate, PL 10.15 Item
15.
10. Check the wiring between the duplex gate solenoid and CN6 on the Main PWB. If neces-
sary, install a new duplex gate solenoid, PL 10.15 Item 4.
11. Check that the following components are clean and rotate freely:
• Duplex roll, PL 10.15 Item 22.
• Duplex roll idlers, PL 10.15 Item 9.
12. If necessary, install new components:
• Exit assembly, PL 10.15 Item 1.
• Right cover assembly, PL 7.30 Item 1.
• Main PWB, PL 1.10 Item 1.
