note:
Be sure to select Plain paper as the Media Type setting and select the correct envelope size before you print.
Printing on Envelopes
You can print on almost any kind of envelope. Load up to
10 envelopes in the printer’s sheet feeder, flap edge first, with the flap side down. Slide the left edge guide against the envelope’s edge.
Set the paper thickness switch to the + position. (Return the switch to the 0 position before you print on regular paper.)
