Loading Envelopes in the Paper Source
• You cannot print on the reverse side (glued side) of envelopes.
While holding the lock release lever of the side paper guides,
slide the guides to the mark for the size of the loaded
envelopes.
The side paper guides move together.
IMPORTANT
Be sure to align the paper guides with the width of the envelopes. If the paper
guides are too loose or too tight, this may result in misfeeds or paper jams.
