Loading envelopes in the bypass tray

Avoid using self-adhesive envelopes. They may cause machine malfunctions.
Check there is no air in the envelopes before loading.
Load only one size and type of envelope at a time.
Before loading envelopes, flatten their leading edges (the edge going into the machine) by running a pencil or ruler across them.
Some kinds of envelope might cause misfeeds, wrinkles or print poorly.
Print quality on envelopes may be uneven if parts of an envelope have different thicknesses. Print one or two envelopes to check print quality.
In a hot and humid environment, the envelope might be output creased or improper printing quality.

Insert the edge of the envelope into the machine.
Adjust the paper guides to the envelope size.
Support the envelope with both hands, and insert it carefully until it stops.
After the envelope is inserted until it stops, the envelope will be automatically fed into the machine a little.

Be sure to load envelopes so that their flaps are on the right. If you do not, the envelopes will become creased.
If printed envelopes come out badly creased, load the envelopes in the opposite direction, and then rotate the print object by 180 degrees using the printer driver before printing. For details, see the printer driver Help.
