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.

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.

Page 33

Printing on special media

Use these guidelines when printing on special types of media.

Transparencies

When printing on transparencies, use the following guidelines:

● Handle transparencies using the edges. Oils from your fingers deposited on the transparency

can cause print quality problems.

● Use only overhead transparencies recommended for use in this printer. Hewlett-Packard

recommends using HP Color LaserJet Transparencies with this printer. HP products are designed to work together for optimum printing results.

● In either the software application or the printer driver, select TRANSPARENCY as the media

type, or print from a tray that is configured for transparencies.

CAUTION Transparencies not designed for LaserJet printing will melt in the printer, causing damage to the

printer. Do not use transparencies designed for monochrome printing.

Glossy paper

When printing on glossy paper, use the following guidelines:

● In either the software application or the driver, select Glossy as the media type, or print from a

tray that is configured for glossy paper.

Select Glossy for media weights up to 105 g/m weights up to 120 g/m

● Because this affects all print jobs, it is important to return the printer to its original settings once

(32 lb bond).

(28 lb bond). Select Heavy Glossy for media

the job has printed.

Note Hewlett-Packard recommends using HP Color LaserJet Soft Gloss paper with this printer. HP

products are designed to work together for optimum printing results. If HP Color LaserJet Soft Gloss paper is not used with this printer, print quality may be compromised.

Colored paper

When printing on colored paper, use the following guidelines:

● Colored paper should be of the same high quality as white xerographic paper.

● Pigments used must be able to withstand the printer fusing temperature of 190° C (374° F) for

0.1 second without deterioration.

● Do not use paper with a colored coating that was added after the paper was produced.

● The printer creates colors by printing patterns of dots, overlaying and varying their spacing to

produce various colors. Varying the shade or color of the paper will affect the shades of the printed colors.

ENWW Printing on special media 19

Page 34

Envelopes

Note Envelopes can be printed only from Tray 1. Set the tray media size to the specific envelope size.

Adhere to the following guidelines to help ensure proper printing on envelopes and to help prevent printer jams:

● Do not load more than 10 envelopes into Tray 1.

● The weight rating of envelopes should not exceed 90 g/m

● Envelopes should be flat.

● Do not use envelopes with windows or clasps.

● Envelopes must not be wrinkled, nicked, or otherwise damaged.

● Envelopes with peel-off adhesive strips must use adhesives that can withstand the heat and

pressures of the printer fusing process.

● Envelopes should be loaded face-down with the top of the envelope to the left, and the short

edge feeding into the printer first.

Note In high humidity environments, envelopes should be printed long-edge first to prevent them from

sealing during printing. For long-edge printing, envelopes should be loaded long edge first, face down. See the Printing envelopes from Tray 1 section in the HP Color LaserJet 3500 and 3700 series printer User Guide to change the printer drivers envelope orientation.

(24 lb bond).

Labels

Note In either the application or the printer driver, select Labels as the media type, or configure Tray 1

for labels.

When printing labels, use the following guidelines:

● Verify that the label adhesive material can tolerate temperatures of 190° C (374° F) for 0.1

second.

● Verify that there is no exposed adhesive material between the labels. Exposed areas can

cause labels to peel off during printing, which can cause paper jams. Exposed adhesive can also cause damage to printer components.

● Do not re-feed a sheet of labels.

● Verify that labels lie flat.

● Do not use labels that are wrinkled, bubbled, or otherwise damaged.

20 Printer description ENWW

Page 35

Heavy paper

When printing on heavy paper, use the following guidelines:

● Any tray will print most heavy media that does not exceed 105 g/m

print from a tray that is configured for heavy paper. Because this setting affects all print jobs, it is important to return the printer back to its original settings once the job has printed.

CAUTION In general, do not use paper that is heavier than the media specification recommended for this printer.

Doing so can cause misfeeds, paper jams, reduced print quality, and excessive mechanical wear.

HP LaserJet tough paper

When printing on HP LaserJet Tough paper, use the following guidelines:

● Handle HP LaserJet Tough paper using the edges. Oils from your fingers deposited on

HP LaserJet Tough paper can cause print quality problems.

● Use only HP LaserJet Tough paper with this printer. HP products are designed to work

together for optimum printing results.

● In either the software application or the printer driver, select TOUGH PAPER as the media

type, or print from a tray that is configured for HP LaserJet Tough paper.

CAUTION Transparent media that are not designed for LaserJet printing will melt in the printer, causing damage

to the printer.

Preprinted forms and letterhead

When printing on preprinted forms and letterhead, use the following guidelines:

● Forms and letterhead must be printed with heat-resistant inks that will not melt, vaporize, or

release hazardous emissions when subjected to the printer fusing temperature of approximately 190° C (374° F) for 0.1 second.

● Inks must be non-flammable and should not adversely affect any printer rollers.

● Forms and letterhead should be sealed in a moisture-proof wrapping to prevent changes

during storage.

● Before loading preprinted paper such as forms and letterhead, verify that the ink on the paper

is dry. During the fusing process, wet ink can come off of preprinted paper.

● When duplex printing on the HP Color LaserJet 3700 series printer, load preprinted forms and

letterhead into Tray 2 and Tray 3 first side up, top edge toward the back of the tray. To load preprinted forms and letterhead into Tray 1, load them with the first side down, bottom edge in first.

● When simplex (1-sided) printing, load preprinted forms and letterhead into Tray 2 and Tray 3

face-up with the top edge of the page to the left. To load preprinted forms and letterhead into Tray 1, place them in the tray with the side to be printed on facing up, and top, short edge in first.

Recycled paper

This printer supports the use of recycled paper. Recycled paper must meet the same specifications as standard paper. See the HP LaserJet Printer Family Print Media Specification Guide. Hewlett-Packard recommends that recycled paper contain no more than five percent ground wood.

Safety statements

Laser safety statement

The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration has implemented regulations for laser products manufactured since August 1, 1976. Compliance is mandatory for products marketed in the United States. The printer is certified as a “Class 1” laser product under the U.S. Department of Health and Human Services (DHHS) Radiation Performance Standard according to the Radiation Control for Health and Safety Act of 1968. Since radiation emitted inside the printer is completely confined within protective housings and external covers, the laser beam cannot escape during any phase of normal user operation.

WARNING! Using controls, making adjustments, or performing procedures other than those specified in this

service manual may result in exposure to hazardous radiation.

Toner safety

Hewlett-Packard encourages responsible disposal of HP LaserJet printer supply items through its Environmental Collection Program. For details on this program, see the recycling instruction guide enclosed with each supply item.

Note In case of toner spills, skin and clothing are best cleaned by removing as much toner as possible

with a dry tissue, then washing with cold water. Hot water causes toner to permanently set into clothing.
