Envelopes
You can load up to 10 envelopes in tray 1. Load envelopes with the flap side down with the
return address positioned to enter the printer first. Do not load stamped envelopes. Load
envelopes only in tray 1. 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 to Envelope and select the correct envelope
size before sending the job to print.
When printing on envelopes:
• Try a sample of any envelopes you are considering using before buying large
quantities.
• Use envelopes made from 90 to 105 g/m
