Wrinkled Envelopes; Fuser Jams - Xerox Phaser 7100 Service Manual

Wrinkled Envelopes

Envelope wrinkling of varying severity can sometimes occur. In general, envelope wrinkling is
considered a laser technology limitation due to the fusing process which relies on heat and pressure to
bond toner to the media. The #10 Commercial envelopes are particularly susceptible to wrinkling.
Testing different manufacturer's envelopes demonstrated that some brands of #10 Commercial
envelopes exhibit less wrinkling when loaded face down with the flap oriented to the right side of the
Bypass Tray not the left as indicated on the tray label.
1. Check the media path for obstructions or debris.
2. Check that the paper Guides are set correctly.
3. Check that the Bypass Tray has not been over filled.
4. Test envelopes from other manufacturers to find the best result.
