HP LaserJet 4250 - Manual (Page 251)

Labels
CAUTION To avoid damaging the printer, use only labels recommended for laser printers. To prevent
serious jams, always use tray 1 to print labels and always use the rear output bin. Never
print on the same sheet of labels more than once or print on a partial sheet of labels.
Label construction
When selecting labels, consider the quality of each component:
● Adhesives: The adhesive material should be stable at 200°C (392°F), the printer's
fusing temperature.
● Arrangement: Only use labels with no exposed backing between them. Labels can peel
off sheets with spaces between the labels, causing serious jams.
● Curl: Prior to printing, labels must lie 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.
For more information, see Printing on labels .
NOTE Choose labels in the printer driver (see Using the printer driver ).
Transparencies
Transparencies used in the printer must be able to withstand 200°C (392°F), the printer's
fusing temperature.
CAUTION To avoid damaging the printer, use only transparencies recommended for use in
HP LaserJet printers, such as HP-brand transparencies. (For ordering information, see
Part
numbers .)

NOTE Choose transparencies in the printer driver (see Using the printer driver ).
