Printing On Special Media; Envelopes - Epson EPL-1220 Reference Manual

Printing on Special Media

You can use many kinds of media including stock paper,
envelopes, labels, and overhead projector transparencies. The
printer feeds most types of media automatically from the MP tray.
The type of paper you use in your printer can affect the quality of
the printed output. The smoother the paper you use, the smoother
and sharper your printing looks.
For best results, store your paper supply in its original wrapper.
Your printouts can be marred by moisture absorbed in the paper.
Do not store paper in a humid or damp environment.
Note:
Since the quality of any particular brand or type of paper may be changed
by the manufacturer at any time, EPSON cannot guarantee the quality
of any type of paper. Always test samples of paper stock before purchasing
large quantities or printing large jobs.
Below are some recommendations for selecting paper and other
print media for your printer.

Envelopes

Load envelopes in the MP tray with the flap edge to the right side
(Commercial 10, International B5, DL) or the flap edge to the front
of the MP tray (C5, C6) and the surface to print facing up. The
printing quality on envelopes may be irregular because different
parts of an envelope have different thicknesses. You can load up
to 10 envelopes (depending on thickness.)
Note:
Be sure to set the paper size switch to Others.
Because thickness and surface characteristics are especially
important for envelopes, test a sample for print quality and proper
feeding before you buy a large number of envelopes.
