The machine has detected paper jammed in the fuser area.
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.
WARNING
Do not touch the fuser while it is hot.
NOTE: If necessary, refer to GP 20 for the acronym list and cross reference lists of more com-
monly recognised part names.
Refer to the following:
• (M20F) Wiring Diagram 3
• (4118) Wiring Diagram 9 and Wiring Diagram 11
• (2218) Wiring Diagram 15 and Wiring Diagram 16
Perform the following:
1. Open the right hand cover. Remove all jammed paper from the fuser area. Ensure that the
paper path is clear.
2. Enter GP 1 Engine Test Mode Entry. Use the sensor test to check EX. This is the PBA
SUB - exit sensor, PL 4.17 Item 3.
3. (M20F) Check the wiring between the PBA SUB - exit sensor and CN6 on the PBA main.
4. (4118) Check the wiring between the PBA SUB - exit sensor and CN7 on the PBA main.
5. (2218) Check the wiring between the PBA SUB - exit sensor and CN9 on the PBA main.
6. Enter GP 1 Engine Test Mode Entry. Check that the motor step - MCK2 (main), PL 4.20
Item 2 runs. Install new components as necessary, PL 4.20.
7. Install new components as necessary:
• ELA HOU - fuser assembly, PL 10.15 Item 1.
• PBA main (M20F), PL 1.10 Item 4.
• PBA main (4118), PL 1.15 Item 9.

supply while performing tasks that do not need electricity. Electricity can cause death or
injury. Moving parts can cause injury.
WARNING
Do not touch the fuser while it is hot.
NOTE: If necessary, refer to GP 20 for the acronym list and cross reference lists of more com-
monly recognised part names.
Refer to the following:
• (M20F) Wiring Diagram 3
• (4118) Wiring Diagram 11
• (2218) Wiring Diagram 15 and Wiring Diagram 16
Perform the following:
1. Remove all of the jammed paper from the exit area.
2. Open the right hand cover. Remove all paper.
3. Check that the paper path is clear.
4. Enter GP 1 Engine Test Mode Entry. Use the sensor test to check OB. This is the PBA
SUB - bin full sensor, PL 10.10 Item 20.
5. (M20F) Check the wiring between the PBA SUB - bin full sensor and CN8 on the PBA
main.
6. (4118) Check the wiring between the PBA SUB - bin full sensor and CN25 on the PBA
main.
7. (2218) Check the wiring between the PBA SUB - bin full sensor and CN10 on the PBA
main.
8. This fault can be caused by the PBA SUB - exit sensor actuator on the ELA HOU fuser
assembly. The actuator can get trapped on the PBA SUB - exit sensor housing. If neces-
sary, install a new ELA HOU - fuser assembly, PL 10.15 Item 1.
9. Enter GP 1 Engine Test Mode Entry. Check that the motor step - MCK2 (main), PL 4.20
Item 2 runs. Install new components as necessary, PL 4.20.
10. Install new components as necessary:
• PBA main (M20F), PL 1.10 Item 4.
• PBA main (4118), PL 1.15 Item 9.
• PBA main (2218), PL 1.20 Item 9.
