Printing envelopes from Tray 1
Many types of envelopes can be printed from Tray 1. Up to 10 envelopes can be stacked in the tray. Printing performance depends on the construction of the envelope.
In the software, set margins at least 15 mm (0.6 inches) from the edge of the envelope.
Envelopes with clasps, snaps, windows, coated linings, exposed self-stick adhesives, or other synthetic materials can severely damage the printer. To avoid jams and possible printer damage, never try to print on both sides of an envelope. Before you load envelopes, make sure they are flat, undamaged, and not stuck together. Do not use envelopes with pressure-sensitive adhesive. To avoid jams, do not remove or insert envelopes during printing.
