Site requirements

The printer must be kept in a proper location to maintain the performance level that has been set at the factory. In particular, be sure that the environment adheres to the specifications listed in this chapter.

Below are recommendations for the printer location and placement. Make sure the printer has the following:

● a well-ventilated, dust-free area

● a hard, level surface (not more than a 2° angle) that can support

approximately 43.4 kg (95.5 lbs)

● a level surface that supports all four corners of the 500-sheet paper feeder

● a constant temperature and humidity. (Do not install near water sources, humidifiers, air

conditioners, refrigerators, or other major appliances)

Make sure to keep the printer away from the following:

● direct sunlight, dust, open flames, or water

● the direct flow of exhaust from air ventilation systems

● magnets and devices that emit a magnetic field

● areas subject to vibration

● walls or other objects (There must be enough space around the printer for proper access and

ventilation. See the figures Space requirements for the HP Color LaserJet 3500 series printer and Space requirements for the HP Color LaserJet 3700 series printer with optional Tray 3, on the following pages.)

Selecting paper

You can use many types of paper and other print media with this printer. This section provides guidelines and specifications for selecting and using different print media.

Before purchasing any paper or specialized forms in quantity, verify that your paper supplier obtains and understands the print media requirements specified in the HP LaserJet Printer Family

Print Media Specification Guide. See the HP Color LaserJet 3500 and 3700 series printer User Guide or HP LaserJet Printer Family

Print Media Specification Guide for ordering information. To download a copy of the HP LaserJet Printer Family Print Media Specification Guide go to http://www.hp.com/support/clj3500

HP Color LaserJet 3500 series and to http://www.hp.com/support/clj3700 LaserJet 3700 series, and then select manuals.

It is possible that paper could meet all of the guidelines in this chapter or the HP LaserJet Printer Family Print Media Specification Guide and still not print satisfactorily. This may be due to abnormal characteristics of the printing environment or to other variables over which HewlettPackard has no control (for example, extremes in temperature and humidity).

Hewlett-Packard recommends testing any paper before buying it in large quantities.

CAUTION Using paper that does not conform to the specifications listed here or in the print media guide can

cause problems that require service. This service is not covered by the Hewlett-Packard warranty or service agreements.

ENWW Selecting paper 15

for the HP Color

for the

Paper to avoid

The printer can handle many types of paper. Use of paper outside the printer specifications will cause a loss of print quality and will increase the chance of paper jams.

● Do not use paper that is too rough.

● Do not use paper with cutouts or perforations, other than standard 3-hole punched paper.

● Do not use multipart forms.

● Do not use paper that has already been printed on, or that has been fed through a

photocopier.

● Do not use paper with a watermark if you are printing solid patterns.

Paper that can damage the printer

In rare circumstances, paper can damage the printer. The following paper must be avoided to prevent possible damage to the printer:

● Do not use paper with staples attached.

● Do not use transparencies designed for Inkjet printers or other low temperature printers, or

transparencies designed for monochrome printing. Use only transparencies that are specified for use with HP Color LaserJet printers.

● Do not use photo paper intended for Inkjet printers.

● Do not use paper that is embossed or coated, and is not designed for the temperatures of the

HP Color LaserJet 3500 and 3700 series printer image fusers. Select paper that can tolerate temperatures of 190° C (374° F) for 0.1 second. HP produces a selection of paper that is designed for the HP Color LaserJet 3500 and 3700 series printer.

● Do not use letterhead paper with low temperature dyes or thermography. Preprinted forms or

letterhead must use inks that can tolerate temperatures of 190° C (374° F) for 0.1 second.

● Do not use any media that produces hazardous emissions, or that melts, offsets, or discolors

when exposed to 190° C (374° F) for 0.1 second.

Print media specifications

For optimum results, use conventional 75 g/m2 to 90 g/m2 (20 to 24 lb) photocopy paper. Verify that the paper is of good quality and is free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, curls, or bent edges.
