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.
CAUTION 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.
To load envelopes into Tray 1
1. Open Tray 1.
2. Slide out the tray extender and, if necessary, open the additional tray extender.
