Labels
To avoid damaging the printer, use only labels recommended for use in monochrome laser
printers. Never print on the same sheet of labels more than once.
CAUTION Do not print on both sides of labels, transparencies, envelopes, custom paper, or paper heavier
than 216 g/m
2
(58 lb bond). Damage to the printer and jams might result.
L abel construction
When selecting labels, consider the quality of each component:
● Adhesives: The adhesive material should be stable at 200°C (392°F), the maximum fusing
temperature of the printer.
● Arrangement: Only use full-sheet labels. Labels can peel off sheets with spaces between
the labels, causing serious jams.
● Curl: Prior to printing, labels must lay flat with no more than 13 mm (0.5 inch) of curl in any
direction.
● Condition: Do not use labels with wrinkles, bubbles, or other indications of separation.
Transparencies
CAUTION Transparencies used in the printer must be able to withstand 200°C (392°F), the maximum fusing
temperature of the printer. To avoid damaging the printer, use only transparencies recommended
for use in monochrome laser printers.
Do not print on both sides of labels, transparencies, envelopes, custom paper, or paper heavier
than 216 g/m
2
(58 lb bond). Damage to the printer and jamming might result.
If you have problems printing transparencies, use optional Tray 1 and send them to the left output
bin or the upper bin.
Envelopes
Note To print envelopes, use optional Tray 1 and print them either to the left output bin or to the upper bin.
