Before using this function, select [Envelope] under Paper Type: Bypass Tray in User Tools. For details, see “System Settings”, Network and System Settings Reference.
Before loading self-adhesive envelopes, be sure to fan them thoroughly. This will prevent them sticking together. If fanning does not prevent them sticking together, load them one by one. Note that some types of envelope cannot be used with this machine.
Open the bypass tray and set the envelopes print side down, flaps open and pointing away from the machine. Push the envelopes into the machine until you hear the beep.

When placing an original on the exposure glass, place the original with the bottom line aligned to the left scale.
When placing an original in the ADF, place the original with the bottom line inserted in the ADF.
Load envelopes with flaps fully open. Otherwise, they might not feed into the machine.
When loading envelopes in the landscape () orientation, set them so that their flaps are closed, facing upward, and pointing toward the back of the machine.
To copy onto custom size envelopes, you must specify the envelope's dimensions. Be sure to include the fully open flap in the horizontal dimension.
Check the envelopes are not damp.
Load only as much envelopes as can be held between the paper guides on the bypass tray. For the number of envelopes that you can set on the bypass tray, see “Recommended Paper Sizes and Types”, About This Machine.
Check there is no air in the envelopes before loading.
To get better print quality, it is recommended that you set the right, left, top, and bottom print margin, to at least 15 mm (0.6 inch) each.
You cannot print envelopes with the Duplex function.
Load only one size and type of envelope at a time.
Before loading envelopes, flatten leading edges (the side going into the machine) by pressing a pencil or ruler across them.
