What paper types can be used in the Manual Feed Slot?

The Manual Feed Slot supports plain paper, thin paper, recycled paper, bond paper, thick paper, labels, and envelopes. You should 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 and pulls it in. If printing on labels or envelopes, open the back cover (face up output tray) before printing. (Page 7)
