For transparency loading instructions, see Loading paper.
Envelopes
You can load up to 10 envelopes in the multipurpose feeder. Load envelopes flap side down, with the
flap closed, and with the return address area on the right. Orient the envelopes so that the edge with
the return address and stamp area will enter the multipurpose feeder last. Do not load stamped
envelopes. Before loading envelopes, fan the stack to prevent them from sticking together. For
envelope loading instructions, see
Loading envelopes.
To ensure the best print quality, set Paper Type (or Media Type in the driver) to Envelope and select
the correct envelope size before sending the job to print
When printing on envelopes:
• Try a sample of any envelopes before buying large quantities.
• Use envelopes made from 90 to 105 g/m
2

– Use metal clasps or string ties
– Have postage stamps attached
– Have any exposed adhesive when the flap is in the sealed or closed position
• Use envelopes that can withstand temperatures of 180°C (356°F) without sealing, excessive
