4.2 Recording Paper Jam
Symptom: Recording paper did not exit paper cassette properly or jam occurred in print area.
Suggested corrective action:
1. Verify that the recording paper conforms to the type specified for use in the machine, and that has
not been damaged or exposed to moisture.
2. Make sure the recording paper is properly loaded into the bypass tray and cassette and the cas-
sette is properly closed.
3. Clean the paper feed rollers of any paper dust buildup. (Clean using a lint-free cotton cloth moist-
ened with a cleaning designed for use on rubber rollers.) Replace the paper feed rollers if worn or
damaged.
4. Check the paper guide in the cassette is adjusted properly to the paper and operation is done.
5. Verify that the paper has reached sensor PSS. If it has, check the operation of PSS.
6. Verify the paper take up roller is turning. If not, check the main motor. If the main motor is turning,
check the operation of the paper feed solenoid PFCL.
7. If the main motor does not turn, replace the main motor, the power supply unit or the main control
PCB.
8. Check for obstructions in the paper path.
Symptom: Recording paper jammed as it was exiting the unit into receive paper tray.
Suggested corrective action:
1. Check for obstruction in the paper path.
2. Check the paper discharge sensor (PDS) for proper operation.
3. Clean the exit roller using a lint-free cloth moistened with a cleaning solution designed for use on
rubber rollers. Replace the exit roller if worn or damaged.
4. Verify the fuser rollers are clean and not damaged. If worn or damaged, replace the fuser.
4.3 Document Feeder Jam
Symptom: Original document did not feed into or exit scanner properly, document feeder error message.
Suggested corrective action:
1. Verify the original documents conform to the specifications designed for use in the machine and
that they are not damaged in any way.
2. Verify the number of documents placed into the feeder does not exceed its maximum capacity.
3. Verify the scanner cover is closed properly.
4. Remove any foreign substances from inside the scanner area.
5. Verify that all of the document feed rollers are clean and not damaged. Clean using a lint-free cot-
ton cloth moistened with a cleaning solution designed for use on rubber rollers. Replace the rollers
if worn or damaged.
6. Check the operation of DS1 at connector P82, pins 3-5, on the Connect A PCB.
7. Check the operation of the separator roller, and the pick-up roller.
8. Verify the operation to the ADF Motor at connector P82, pins 8-12, on the Connect A PCB.
9. Verify that the document feeds into the unit and stops. If the document does not stop, check the op-
eration of DS2 at connector P82, pins 6-8, on the Connect A PCB.
10. Check all connectors and cables.
11. Check the operation of the main control board.
