Troubleshooting flow chart 6:
Recording paper feed jam, transport jam, ejection jam, recording size error

Note 1:

The paper length stop must be set for the correct paper size, but should not be "pinching" the

paper. Paper should not be loaded above the "paper fill" indicator.

Note 2:

The programmed settings of user function number 10 (1st cassette size) and user function

number 11 (2nd cassette size) (optional) should be set to match the paper size loaded in each paper
cassette. If not, a "logical" jam will follow.

Note 3:

Always vacuum loose toner from inside the printer. If toner has spilled, pay special attention to

cleaning it from all drive gears. (Including the fuser roller gear and transfer (TR) Gear). Toner infused in
the drive gear chain can cause jamming.

Note 4:

Check fuser heat and back up rollers for dirt or toner contamination. Clean as necessary. Always

allow fuser to cool before cleaning.
Use Caution! Fuser area is very hot.
