Printing Envelopes
Many types of envelopes can be printed from Tray 1. (Up to 10 can
be stacked in the tray.) Printing performance depends on the
construction of the envelope. Always test a few sample envelopes
before purchasing a large quantity.
• Set margins at least 0.6 inch (15 mm) from the edge of the
envelope.
• To minimize curl and wrinkling, always print envelopes to the rear
output bin.
When you print large numbers of envelopes and standard paper,
for best printing performance print paper first, then envelopes. To
alternate paper and envelopes, from the Configuration Menu in the
printer’s control panel select SMALL PAPER SPEED=SLOW.
WARNING! Never use envelopes with coated linings, exposed self-stick
adhesives, or other synthetic materials. These items can emit
noxious fumes.
Caution Envelopes with clasps, snaps, windows, coated linings, exposed
self-stick adhesives, or other synthetic materials can severely
damage the printer.
To avoid jamming and possible printer damage, never try to print on
both sides of an envelope.
Before you load envelopes, make sure they are flat and not
damaged or stuck together. Do not use envelopes with
pressure-sensitive adhesive. (For envelope specifications, see
page A-9.)
