This section provides information on media usage for the printer, changing print settings, and performing basic printing tasks.

Selecting print media

The printer is designed to work well with most types of office paper. It is best to test a variety of print media types before buying large quantities. Use HP media for optimum print quality. See

and accessories. For more information about HP media, see www.hp.com.

Tips for selecting and using print media

For the best results, observe the following guidelines.

HP supplies

Always use media that conforms to the printer specifications. See

●

for supported media.

Select the appropriate media type and size from the printer driver. See

●

Load only one type of media at a time into a tray.

●

● For the input tray, load media print-side down and aligned against the right and back edges of

the tray. See

Do not overload the tray. See

●

To prevent jams, poor print quality, and other printer problems, avoid the following media:

●

Multipart forms

●

Media that is damaged, curled, or wrinkled

●

Media with cutouts or perforations

●

● Media that is heavily textured, embossed, or does not accept ink well

Media that is too lightweight or stretches easily

●

If using recycled media, you might need to lower the ink volume in the printer software to prevent

●

smeared ink. However, if you lower the ink volume too much, the output might appear washed out.

● If using recycled media, you might need to use another media type to prevent paper jams.

Loading media.

Understanding specifications for supported media.

Understanding specifications

Changing print settings.

Cards and envelopes

● Avoid envelopes that have a very slick finish, self-stick adhesives, clasps, or windows. Also avoid

cards and envelopes with thick, irregular, or curled edges, or areas that are wrinkled, torn, or otherwise damaged.

Use tightly constructed envelopes, and make sure the folds are sharply creased.

●

Load envelopes into the printer according to the icon on the tray.

●

Photo paper

Use the Best mode to print photographs. Note that in this mode, printing takes longer and more

●

memory is required from your computer.

Remove each sheet as it prints and set it aside to dry. Allowing wet media to stack up might

●

cause smearing.

12 Chapter 3 Using the printer ENWW

Transparencies

Insert transparencies with the rough side down and the adhesive strip pointing towards the back

●

of the printer.

Use the Best mode to print transparencies. This mode provides longer drying time and ensures

●

that the ink dries completely before the next page is delivered to the output tray. Allowing wet media to stack up might cause smearing.

Custom-size media

Use only custom-size media supported by the printer.

●

If your application supports custom-size media, set the media size in the application before

●

printing the document. If not, set the size in the printer driver. You might need to reformat existing documents to print them correctly on custom-size media.

Understanding specifications for supported media

This section provides information regarding the sizes, types, and weights of media that the printer supports. It also provides information on the tray capacity.
