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.
Fuser Jams
1. Check that the Fuser Unit is properly seated, locked, and operates normally.
2. Ensure that the media is in good condition and is listed on the Recommended Media List as
supported; quality office printer paper works best. Try loading new media from a fresh ream.
