Printing On Envelopes - Canon Color Bubble Jet BJC-1000 Series User Manual

Do not try to load paper into the sheet feeder beyond the paper
limit mark ( ) on the left side or the tabs on both sides of the sheet
feeder; stacking too much paper may cause paper feeding or
printing problems.

Printing on Envelopes

You can stack up to 5 envelopes in the sheet feeder or you can manually
feed envelopes one at a time through the sheet feeder.
U.S. Commercial number 10 (COM10) envelopes, Canon envelopes, and
European DL envelopes are recommended. You may be able to stack
envelopes of other sizes in the sheet feeder; however, Canon cannot
guarantee consistent performance on envelope sizes other than COM10,
Canon, and DL.
