How do I print envelopes with this printer?

Use only Tray 1 to print envelopes, which holds up to 10 envelopes. In the print driver, select the Paper/Quality tab, set the paper size to the correct envelope size, set Paper type to Envelope, and select Manual feed as the paper source. Load envelopes face-up with the short postage-end leading into the printer. (Page 28)
