Printing on envelopes
You can print on envelopes from tray 1 or the optional envelope feeder. Tray 1 holds up to
10 envelopes and supports standard or custom sizes. The optional envelope feeder holds up
to 75 envelopes and supports only standard envelope sizes.
For printing on any size of envelope, make sure to set the margins in your program at least
15 mm (0.6 inch) from the edge of the envelope.
Printing performance depends on the construction of the envelope. Always test a few
sample envelopes before purchasing a large quantity. For envelope specifications, see
Envelopes .
WARNING! Never use envelopes that contain coated linings, exposed self-stick adhesives, or other
synthetic materials. These items can emit noxious fumes.
CAUTION Envelopes that have clasps, snaps, windows, coated linings, exposed self-stick adhesives,
or other synthetic materials can severely damage the MFP. To avoid jamming and possible
MFP damage, never try to print on both sides of an envelope. Before you load envelopes,
make sure that they are flat and are not damaged or stuck together. Do not use envelopes
that have pressure-sensitive adhesive.
Note The MFP prints at a slower speed when printing on envelopes.
Loading envelopes in tray 1
Many types of envelopes can be printed on from tray 1. Up to 10 can be stacked in the tray.
See
Envelopes for specifications.
To load envelopes in tray 1
1. Open tray 1, but do not pull out the extension. Most envelopes feed best without the
extension. However, oversize envelopes might need the extension.
2. Load up to 10 envelopes in the center of tray 1 with the front side facing up, and the
postage-end toward the MFP. Slide the envelopes into the MFP as far as they will go
without forcing them.
