What types of media can I use with the Manual Feed Slot?

The Manual Feed Slot supports plain paper, thin paper, recycled paper, bond paper, thick paper, labels, and envelopes. When using labels or envelopes, you should open the back cover (face up output tray) before printing so that printed paper exits onto the face up output tray. Use both hands to insert one sheet at a time and continue pressing the paper against the rollers for about two seconds until the machine grabs it. (Page 11)
