•
Envelopes with transparent windows, holes, cutouts or perforations.
NOTE:
•
Before printing envelopes, fan the stack well to avoid paper jams and misfeeds.

Do not load different types of paper at the same time in the paper tray because it may
cause paper jams or misfeeds.
•
Do not print envelopes using duplex printing.
•
If the application software does not support paper size selection in its print menu, you can
change the paper size on the printers control panel under the
PAPER
