Envelopes
The print quality of envelopes may be irregular because different
parts of an envelope have different thicknesses. Print one or two
envelopes to check the print quality.

Caution:
Do not use window envelopes unless they are specifically
designed for laser printers. The plastic on most window envelopes
will melt when it comes into contact with the fuser.
Note:
❏ Duplex printing is not available for envelopes.
❏ Depending on the quality of envelopes, the printing environment,
or the printing procedure, envelopes might be wrinkled. Make a trial
print run before you print on a lot of envelopes.
Envelopes can be loaded into the MP tray only (up to a 10 mm
thick stack). When using envelopes, you should make paper
settings as shown below:
❏ Make settings on the Basic Settings menu (for Windows) or
the Basic Settings dialog box (for Macintosh) in the printer
driver as shown below:
❏ You can also make these settings on the Tray Menu and the
Setup Menu in the control panel.
