To load envelopes in tray 1

CAUTION

Never use envelopes with clasps, snaps, windows, coated linings, or self-stick adhesives. These items can damage the printer. Never try to print on both sides of an envelope. Media jams and printer damage can result.

Open tray 1.

Place up to ten envelopes in tray 1 between the media width guides, face up, with the back flap against the input tray and the return address area (short edge of the envelope) towards the printer.

Orienting Media in Tray 1

Place media into the input tray with the side to be printed on face up for single-sided printing. For letter- or A4-sized media, place the top of the page toward the rear of the printer and the long edge toward the printer. For media sizes larger than letter and A4, place the top (short) edge of the page toward the printer.

Load letterhead and preprinted forms face up.

The duplexer prints the second side of the paper first, so paper such as letterhead and preprinted paper needs to be oriented as shown.

Loading Media 24

• Load letter and A4 paper with the front side down and

• Load other sizes of paper with the front side down

and the top, short edge toward the printer for double-sided printing.

Loading Media 25

To load media into trays 2 and 3

Firmly grip the handle in the center of the input tray, squeeze the release lever, and pull the input tray out until it stops.

CAUTION

Do not place anything in the input tray to the left of the media guides because the input tray will not be able to lift the media to print and could damage the input tray.

Loading Media 31

Configuring Media Type and Size

Configure the media type (such as plain paper, letterhead, or transparencies) for each of the input trays. If the media type and size have been correctly configured for the input tra ys, the printer will print based on the type and size of media and will automatically use the correct input tray. Configuring the media type is beneficial for several reasons:

• Setting the media type prevents printing on the

wrong, possibly expensive, media.

• The printer will automatically adjust its print speed to

accommodate special media (such as card stock, labels, and transparencies). These adjustments will give the best quality output, saving time and resources.

Note

If the media type is not set properly, the printer might not print on the correct media or at the correct speed for the media type, which can result in poor print quality.

Media Jams

Removing Jammed Media

The procedures on the following pages explain how to clear the most commonly occurring jams. After all jammed media have been removed, the printer will warm up and resume printing.

The printer control panel displays messages about where jams occur and which doors to open to clear jams. As a first step, try opening and then closing the front door of the printer. The printer will attempt to clear a jam from the paper path and send the page to an output bin.

If the printer does not clear the jam, try the following:

• Remove all portions of the jammed media from the

printer.

• After removing media that has jammed in one area of

the printer, check other areas to make sure all media has been removed.

Media Jams 34

Solving Repetitive Media Jams

If the printer continues to jam, try the following:

• Use only media that meets the media specifications

detailed in “Loading Media” on page 17.

• Make sure that the media is correctly loaded in the

input trays and that all media width guides are correctly set.

• Make sure the tray is not overloaded with media.

• Do not use media that is torn, worn, or irregular.

• Turn over the stack of media in the tray.

• Print heavy media from tray 1.

If the printer continues to jam, contact a local authorized HP service provider. For more information on solving repetitive jams, see the online user guide.

Media Jams 35

To clear jams from the lower right door

Open the lower right door.

Remove any jammed media.

At the left side of the opening, pull the green tab

down to lower the bar, remove any jammed media, and release the tab.
