HP 1018 - Manual (Page 29)

Labels
HP recommends that you print labels from the priority feed slot.
CAUTION Do not feed a sheet of labels through the printer more than once. The adhesive degrades
and might damage the printer.
Label construction
When selecting labels, consider the quality of the following components:
● Adhesives: The adhesive material should be stable at 200°C (392°F), the printer's
maximum temperature.
● Arrangement: Only use labels with no exposed backing between them. Labels can peel
off sheets that have spaces between the labels, causing serious jams.
● Curl: Prior to printing, labels must lie flat with no more than 13 mm (0.5 inches) of curl in
any direction.
● Condition: Do not use labels with wrinkles, bubbles, or other indications of separation.
Transparencies
Transparencies must be able to withstand the printer's maximum temperature of 200°C
(392°F).
Envelopes
HP recommends that you print envelopes from the priority feed slot.
Envelope construction
Envelope construction is critical. Envelope fold lines can vary considerably, not only between
manufacturers, but also within a box from the same manufacturer. Successful printing on
envelopes depends upon the quality of the envelopes. When selecting envelopes, consider
the following components:
● Weight: The weight of the envelope paper should not exceed 90 g/m 2 (24 lb) or jamming
might result.
● Construction: Prior to printing, envelopes should lie flat with less than 6 mm
(0.25 inches) curl and should not contain air. Envelopes that trap air might cause
problems. Do not use envelopes that contain clasps, snaps, tie strings, transparent
windows, holes, perforations, cut outs, synthetic materials, stamping, or embossing. Do
not use envelopes with adhesives that do not require moistening, but rely instead on
pressure to seal them.
● Condition: Make sure that the envelopes are not wrinkled, nicked, or otherwise
damaged. Make sure that the envelopes do not have any exposed adhesive.
● Sizes: The envelope sizes range from 90 x 160 mm (3.5 x 6.3 inches) to 178 x 254 mm
(7 x 10 inches).
