you can eliminate #1, #4 and most likely #2....
1. Too much toner on page when printing with high toner coverage. There is a very high toner coverage with the paper sometimes wrapping around the fuser roller and sticking thus causing the jam.
In the printer driver, select TONER REDUCTION which is located under the IMAGE tab.
2. Incorrect setting of DIPswitch 8-5. This DIPswitch default is normally set to 0 or disabled.
Enable DIPswitch 8-5 setting to 1. Depending on paper type, thickness, weight and size, enabling this DIPswitch increases the reversing speed, closing the timing gap between PS17 (Fusing Paper Exit) and PS13 (Paper Exit).
3. Paper Exit sensor (PS13) is not flagging correctly.
Check the operation of PS13 in I/O mode 20-8. The correct reading is 000 (LOW) when no paper is present and 001 (HI) when paper is present. Replace PS13 (p/n 08AA 8551 2) if needed.
Note: The Paper exit Relay Wiring/2 harness for PS13 may also need to be replaced (p/n A03U N226 00).
4. Damaged linkage for paper exit gate or failed paper exit solenoid SD4. The jam occurs when duplexing either face up or face down. Paper stops in the inversion section at reverse roller/Lw before entering the ADU section. All motors and sensors test good in state confirmation mode.
Test SD4 in state confirmation mode 80-0. Repair linkage (p/n 65AA 4928 0) or replace SD4 (p/n 65AA R704 00) if deemed necessary.
5. Broken Locking Cam. (DIAGRAM ATTACHED)
Replace Locking Cam (p/n 65AA 5032 0)
CHECK OUT #3 would be my guess... then look at #5...
What is the meter of the machine?
What is the count of the decurling rollers (exit de-curling)
