Envelopes

This section gives you various details about and recommendations concerning envelopes.

Do not use window envelopes.
Fan the envelopes before loading them to separate them and prevent the glue on them from causing them to stick together.
Some kinds of envelope might cause misfeeds, wrinkles or print poorly.
When loading envelopes in the orientation, load them with flaps closed.
Before loading envelopes, press down on them to remove any air from inside, flatten out all four edges. If they are bent or curled, flatten their leading edges (the edge going into the machine) by running a pencil or ruler across them.
When loading envelopes, do not stack paper over the limit mark. If you squeeze extra envelopes into the bypass tray, misfeeds might occur.

In copier mode

When copying onto envelopes, load them according to the applicable orientation shown below.

How to load envelopes
Orientation of envelopes	Exposure glass	Tray 1	Bypass tray
Side-opening envelopes	Flaps: closed Bottom side of envelopes: toward the front of the machine Side to be scanned: face down	Flaps: closed Bottom side of envelopes: toward the left of the machine Side to be printed: face down	Flaps: closed Bottom side of envelopes: toward the left of the machine Side to be printed: face up

When loading envelopes, specify the envelope size and thickness. For details, see "Copying onto Envelopes", Copy/ Document Server.

In printer mode

When printing onto envelopes, load them according to the applicable orientation shown below:

How to load envelopes
Types of envelopes	Tray 1	Bypass tray
Side-opening envelopes	Flaps: closed Bottom side of envelopes: toward the left of the machine Side to be printed: face down	Flaps: closed Bottom side of envelopes: toward the left of the machine Side to be printed: face up

When loading envelopes, select "Envelope" as the paper types using both the User Tools and printer driver, and specify the thickness of envelopes. For details, see "Printing on Envelopes", Print.

Recommended envelopes

For information about recommended envelopes, contact your local dealer.

For details about the sizes of envelopes you can load, see Recommended Paper Sizes and Types .

Load only one size and type of envelope at a time.
To get better output quality, it is recommended that you set the leading-edge print margin to at least 15 mm (0.6 inches) and the other margins to at least 10 mm (0.4 inches) each.
Output quality on envelopes may be uneven if parts of an envelope have differing thicknesses. Print one or two envelopes to check print quality.
Flatten out prints if they are creased or curled.
Check the envelopes are not damp.
High temperature and high humidity conditions can reduce print quality and cause envelopes to become creased.
Depending on the environment, copying or printing on envelopes may wrinkle them even if they are recommended.
Certain types of envelopes might come out creased, dirtied, or misprinted. If you are printing a solid color on an envelope, lines may appear where the overlapped edges of the envelope make it thicker.
