General guidelines

Locating and placing the printer correctly are important in maintaining the performance level that has been set at the factory. In particular, be sure to adhere to the environmental specifications listed in this chapter. The following are recommendations for locating and placing the printer:

●

Install in a well-ventilated, dust-free area.

●

Install on a hard, level surface.

●

Install where the temperature and humidity do not change abruptly. Do not install near water sources, humidifiers, air conditioners, refrigerators, or other major appliances.

●

Do not expose the printer to direct sunlight, dust, open flames, or ammonia fumes.

●

Install the printer away from w alls or other objects. There m ust be enough space around the printer for proper access and ventilation (see figure 1 on page 25).

●

Install the printer away from the direct flow of exhaust from air ventilation systems.

Media requirements

Selecting media

Many types of paper and other print media can be used with the printer, within certain specifications. Using media that does not meet the specifications outlined in this chapter can increase the incidence of media jams, contribute to repair and maintenance costs, and cause premature wear, print quality problems, and problems requiring service. This service might not be covered by the HP warranty or service agreements.

Before purchasing media or specialized f orms, test a small quantity in the printer. Make sure your media supplier obtains and understands the media specifications in the

Specification Guide

. For ordering information, see page 445.

Note It is possible that media could meet all of the specifications in this

chapter and still not print satisfactorily. This might be caused by abnormal characteristics of the printing environment, such as extremes in temperature and humidity.

●

For complete media specifications, see the

Family Paper Specification Guide

●

Use only print media that meet the specifications outlined in this chapter.

●

Do not try to print unsupported sizes or weights of media or other unsupported media.

●

Always handle transparencies and glossy media b y their edges to avoid fingerprints in the image area.

●

Adhesives on any type of media must be compatible with the printer’s fusing temperatures (approximately 190° C or 374° F).

●

Do not use media that have already passed through the printer or through a copy machine, even if there is no printing on the page.

●

Recycled media can be used with this printer. Recycled media must meet the specifications described in this chapter.

Media requirements

Media capacity and sizes for input trays

The following table lists the types and sizes of media supported by each input tray. For best results, use HP LaserJet paper or conventional white copier paper. The media should be of good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, voids, perforations, and curled or bent edges. For a complete list of media specifications, see the
