Label Guidelines
The printer can print on many labels designed for use with laser
printers. These labels are supplied in letter-size and A4-size sheets.
When printing on labels, be sure to select
Labels
in the
PAPER
TYPE
menu in the
PAPER MENU
.
Do not load labels together with paper or transparencies in the
same paper tray. Combining print materials can cause feeding
problems.
Do not load partial sheets with areas exposed by missing labels.
This can cause labels to peel off during printing, resulting in a
paper jam. Partial sheets will also contaminate your printer and
your cartridge with adhesive, and could void your printer and
cartridge warranties.
Labels are one of the most difficult print materials for laser
printers. A special fuser cleaner should be used for label
application to optimize feed reliability. See “Ordering a Label
Fuser Cleaner” on page 248 for more information.
