Printing envelopes
With the optional envelope feeder, the printer will automatically feed
up to 75 envelopes. To order an envelope feeder, see “Ordering
information” on page 22. To print with the envelope feeder, see
“Feeding envelopes automatically (optional envelope feeder)” on
page 57. For envelope specifications, see “Envelopes” on page 197.
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.
● In the software, set margins at least 15 mm (0.6 in) from the edge
of the envelope.
● Open the rear output bin to get a straight paper path. This
produces better results if envelopes are curling.
If you print large quantities of envelopes continuously or if you
interleave envelopes with wide media, you might need to select
SMALL
PAPER SPEED = SLOW
at the printer control panel. This setting reduces
the throughput speed of narrow media to allow the heat generated
from printing this media to dissipate. Although using this feature will
slow your printer's throughput speed, it will help protect your printer
from damage while ensuring excellent print quality.
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.
