Tips on using transparencies
Print samples on the transparencies being considered for use before buying large quantities.
When printing on transparencies:
•
Feed transparencies from any tray or drawer, except the optional 2,000
‑
sheet high
‑
capacity feeder.
•
Use transparencies designed specifically for laser printers. Check with the manufacturer or vendor to ensure
transparencies are able to withstand temperatures up to 170°C (338°F) without melting, discoloring, offsetting, or
releasing hazardous emissions.
•
To prevent print quality problems, avoid getting fingerprints on the transparencies.
•
Before loading transparencies, flex the stack to prevent sheets from sticking together.

Tips on using envelopes
Print samples on the envelopes being considered for use before buying large quantities.
•
Use envelopes designed specifically for laser/LED printers. Check with the manufacturer or vendor to ensure that
the envelopes can withstand temperatures up to 220°C (446°F) without sealing, wrinkling, curling excessively, or
releasing hazardous emissions.
•
For best performance, use envelopes made from 90 g/m
2
(24 lb bond) paper or 25% cotton. All
‑
cotton envelopes
must not exceed 70 g/m
2
(20 lb bond) weight.
•
Use only new envelopes from undamaged packages.
•
To optimize performance and minimize jams, do not use envelopes that:
–
Have excessive curl or twist
–
Are stuck together or damaged in any way
–
Have windows, holes, perforations, cutouts, or embossing
–
Have metal clasps, string ties, or folding bars
–
Have an interlocking design

Have postage stamps attached
–
Have any exposed adhesive when the flap is in the sealed or closed position
–
Have bent corners
–
Have rough, cockle, or laid finishes
•
Adjust the width guides to fit the width of the envelopes.
Note:
A combination of high humidity (over 60%) and the high printing temperature may wrinkle or seal envelopes.
