Use only paper envelopes specified in the Supported Papers table. Successful envelope
printing is highly dependent on the quality and construction of the envelopes. Use
envelopes made specifically for laser printers.

■

It is recommended that you maintain constant temperatures and relative humidity.

■

Store unused envelopes in their packaging to avoid the effects of moisture and dryness
which can affect print quality and cause wrinkling. Excessive moisture can cause the
envelopes to seal before or during printing.

■

Avoid padded envelopes; purchase envelopes that lie flat on a surface.

■

Remove air “bubbles” from the envelopes before loading by setting a heavy book on top of
the envelopes.

■

If wrinkling or embossing problems occur, use a different brand of envelopes made
specifically for laser printers.

Preparing to Print

Follow these guidelines to prevent wrinkling problems:

■

Print only on the front of the envelope.

■

Perform these steps when using an application that includes a tool for creating an envelope
document:

■

Select facedown.

■

Select the feed method with the image centered.

■

Clear Clockwise Rotation.

■

Load a maximum stack height of 10 mm (.4 in.) for Tray 1 (MPT) and 43 mm (1.7 in.) for
the optional Envelope Tray at a time.

■

Avoid printing over the area where the envelope seams meet.

■

When using commercial flap envelopes with side seams (vs. diagonal seams) verify that
the side seams are cut all the way to the corner of the envelope.

Caution:

Never use envelopes with windows or metal clasps; they can damage the printer.
