"Printing Envelopes" on page 2-52

■

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.

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.
