ENVELOPES
Most envelopes will perform acceptably on your printer. However; some
envelopes will have feeding and print quality problems because of their
construction. A suitable envelope should have edges with a straight, well
creased folds and should not have more than two thickness of paper along
the lead edge. The envelope should lie flat and not have baggy or flimsy
construction. Purchase quality envelopes only from a supplier who
understands that the envelopes will be used in a laser printer. All
envelopes should be tested prior to use to ensure desirable print results.
Envelope Types to Avoid
1. Envelopes constructed with a paper with a weight that exceeds the
paper weight specifications for the printer.
2. Poorly manufactured envelopes with edges that are not straight or
consistently square.
3. Envelopes with "baggy" construction or folds that are not sharply
creased.
4. Envelopes with transparent windows, holes, cutouts or perforations.
