REVENTING
This section explains how to prevent and remove paper jams. There are several things you can do to prevent paper
jams.
Make sure the paper in not folded, wrinkled, or curled.
Do not overfill the paper trays. Paper Tray 1 and 2 have a fill-limit mark on the inside left side.
Use paper, envelopes, labels, and transparencies that match the printer specifications (see page xx).
If you have problems with double feeding, remove the media from the tray and fan the sheets. They may be
sticking together.
note:
Do not fan transparencies since this increases static.
Store all media in a dry location.
Make sure you have loaded the paper printing-side up. Many manufacturers place an arrow on the end of the
wrapper to indicate the printing side.

Understanding the Paper Path

The following illustration shows the printer's paper path. Understanding this path will help you locate paper
jams. The paper is picked up from Paper Tray 1 (or 2) and passed under the Transfer Drum. It then passes through
the Fuser Unit and is delivered to the Output Tray on the top of the printer.
Paper jams occur in the following three areas.
1.
The top Fuser Roller/output area. Operator Panel will report OUTER JAM.
2.
The back Transfer Unit area. Operator Panel will report INNER JAM or DRUM JAM.
3.
The Paper Tray feed area. Error message on Operator Panel will report MISFEED JAM.
note:
Frequent jams in any area indicate that area should be checked, repaired, or cleaned.
