•
Do not use preprinted card stock manufactured with chemicals that may contaminate the printer. Preprinting
introduces semi
‑
liquid and volatile components into the printer.
•
Use grain short card stock when possible.
Tips on using envelopes
Print samples on the envelopes being considered for use before buying large quantities.
•
Use envelopes designed specifically for laser printers. Check with the manufacturer or vendor to ensure that the
envelopes can withstand temperatures up to 230°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 high printing temperature may wrinkle or seal envelopes.
Tips on using labels
Print samples on the labels being considered for use before buying large quantities.
Note:
Use only paper label sheets. Vinyl, pharmacy, and two
‑
sided labels are not supported.
For more information on label printing, characteristics, and design, see the
Card Stock & Label Guide
available at

.
When printing on labels:
•
Use labels designed specifically for laser printers. Check with the manufacturer or vendor to verify that:
–
The labels can withstand temperatures up to 240°C (464°F) without sealing, excessive curling, wrinkling, or
releasing hazardous emissions.
–
Label adhesives, face sheet (printable stock), and topcoats can withstand up to 172
‑
kPa (25
‑
psi) pressure without
delaminating, oozing around the edges, or releasing hazardous fumes.
•
Do not use labels with slick backing material.
•
Use full label sheets. Partial sheets may cause labels to peel off during printing, resulting in a jam. Partial sheets
also contaminate the printer and the cartridge with adhesive, and could void the printer and toner cartridge
warranties.
