Guidelines

Buying and Storing Envelopes

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.

For more information, go to Reference/Printing/Supported Papers on the User Documentation CD-ROM.

Preparing to Print

Follow these guidelines to prevent wrinkling problems:

Use only Tray 1 (MPT) to print envelopes.

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 of 10 envelopes at a time. This printer is not designed to handle high-capacity production envelope printing.

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.
