Appendix 3: Print Media Specifications
Envelopes
You can print envelopes by feeding them from the Multi-Purpose tray. Only use good
quality envelopes.
Check envelopes and ensure the following conditions are met:
The weight is within the specifications for envelopes described in Table A3-1 (see
page 185).
Edges are square and sharply folded.
Joints are diagonal and flaps are the ordinary gummed type. This is the most
common type of envelope for office use. This design is sturdy and can withstand
being fed through the printer.
Never use the following types of envelopes:
Envelopes that are damaged, curled, wrinkled or irregular in shape. Flaps must be
folded closed and flat.
Envelopes with fasteners, snaps or windows made of artificial materials such as
metal or plastic. Metal and plastic fasteners can cause serious damage to the printer.
