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.

WARNING!

Although this printer supports transparencies between 4 and 5

●

mils (0.10 to 0.13 mm) thick, HP recommends using transparencies that are 5 mil (0.13 mm) thick.

To prevent damage to the printer, transparencies must be able to

deposited on the transparencies, causing print quality problems. Also, allow transparencies to cool before handling to prevent curling.

Allow transparencies to cool before handling to prevent burns.

Media requirements

Glossy media

If you want the effect of glossy media, use only HP LaserJet glossy media in this printer. For ordering information, see page 445.

Heavy paper stock

Heavy paper stock is any paper heavier than 28 lb up to 58 lb (105 to 216 g/m2) bond. Always print heavy paper stock from tray 1. In the printer driver, select Heavy Paper or Cardstock as the paper type on the paper tab to ensure the correct finish on the media. Also, use the left (face-up) output bin to prevent media jams. For more information on changing the printer driver settings, see the online help.

not

use extremely heavy paper stock (greater than 58 lb, or

Do 216 g/m2 bond). Misfeeds, mis-stacking, media jams, poor toner fusing, poor print quality, and excessive mechanical wear can result.

Colored media

Colored media should be of the same high quality as white xerographic paper. Pigments used must be able to withstand the printer’s fusing temperature (approximately 190° C or 374° F). Do not use media with a colored coating that was added after the media was produced.

The printer cannot detect the color of media you are using. Varying the shade or color of the media can change the shades of the printed colors.

32 Chapter 1 - Product information

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. This 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 this printer is completely confined within protective housings and external covers, the laser beam cannot escape during any phase of normal user operation.

Product information sheet

The Toner Product Information Sheet can be obtained by calling U.S. HP FIRST (Fax Information Retrieval Support Technology) at (1) (800) 231-9300. International customers should see page 52 for appropriate phone numbers and information.

Toner safety

Toner is composed of plastic and a small amount of pigment. Avoid breathing toner particles; toner might be harmful to your health. T oner can also stain clothing. 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 melt and permanently fuse into clothing.

Material Safety Data Sheet

The Toner Cartridge/Drum MSDS can be obtained by calling U.S. HP FIRST (Fax Information Retrieval Support Technology) at (1) (800) 231-9300. Use Index number 7 for a listing of the Toner Cartridge/Drum Material/Chemical Safety Data Sheets. International customers should see page 52 for appropriate phone numbers and information.

Safety information

Ozone safety

Ozone emission

The corona assemblies found in laser printers and photocopiers generate ozone gas (O3) as a by-product of the electrophotographic process. Ozone is generated only while the printer is printing (while the coronas are energized).

This HP LaserJet printer contains an charcoal filter to protect office air quality. See page 105 for suggested replacement intervals.

Ozone standards

Standards for exposure to ozone have been established by the Department of Labor - Occupational Safety and Health Administration (DOL-OSHA) and the American Conference of Governmental Industrial Hygienists (ACGIH). These standards are 0.1 parts per million as a time-weighted aver age and a ceiling limit respectively. All HP LaserJet family printers meet these standards when shipped from the factory.

Recommendations for minimizing ozone exposure

Some people are extremely sensitive to ozone. In such cases, it is advisable to position the printer away from the sensitive user . Also, a more frequent filter replacement might be necessary.

Almost all ozone concerns arise from abnormal site or operating conditions. The following conditions might generate an ozone complaint:

●

installation of multiple laser printers in a confined area

●

extremely low relative humidity

●

poor room ventilation

●

the exhaust port of the printer is directed towards the face of personnel

●

the existing ozone filter is in poor condition

●

long, continuous printing combined with any of the above

Inspect your work environment for the operating conditions listed above if you believe ozone emissions are a problem in your area. (Your employer is responsible for providing a work environment that is free of these conditions.)

If the printer was shipped with an optional HP JetDirect internal print server, one of two types is installed:

z HP JetDirect Ethernet print server supports up to three different

network interface cables—RJ-45 (unshielded twisted pair) for 10Base-T networks, BNC (coaxial) for 10Base2 networks, and DIN-8 for LocalTalk networks. This print server supports only one Ethernet connection at a time—RJ-45 or BNC.

z HP JetDirect 10/100TX print server supports RJ-45 (unshielded

twisted pair) for 10Base-T or 100Base-TX networks.



connector. Attach another ThinLAN cable section, or (if it is at the end of the



network) a 50-ohm terminator on the other side of the BNC “T” connector.

Plug the BNC “T” connector into the BNC port.



Connecting to a LocalTalk network

Plug the end of the DIN-8 cable into the LocalTalk port.



Note

The printer can be connected to a LocalTalk network in addition to an Ethernet or 10Base2 network.

If you use only the LocalTalk port, EIO 1 INITIALIZING appears every time you turn the printer on if you have an HP JetDirect internal print server installed in EIO port 1. The message should not interfere with normal printing through LocalTalk. If it does not clear within approximately five minutes, there is a problem with the print server or the network. To prevent the message from appearing during normal operation, connect a BNC “T” connector with two 50-ohm terminators to the BNC port.

Connecting the printer to the network

Connecting a parallel cable

Figure 11. Parallel cable connection

 To print through the parallel port, the printer requires a 25-pin

male/micro 36-pin male (“C-size”) parallel cable that is IEEE-1284 compliant. The cable is included with the base model of this printer only. It must be purchased separately for other printer models.

Installing the consumables

Configuring input trays

When input trays are configured correctly, the printer prints based on media type and size and automatically uses the correct input tray.

Note Setting the media type is necessary for best print quality on envelopes,

paper greater than 24 up to 28 lb (90 to 105 g/m2) bond paper, and paper greater than 28 lb (105 g/m2) bond.

For example, tray 2 could contain letterhead; tray 3, plain legal-sized paper; and the 2,000-sheet input unit, plain letter-sized paper. If the trays are configured correctly, when you set up a print job you can choose the media type and size in the printer driver, and the printer automatically prints from the correct input tray.

Selecting the mode for tray 1

Tray 1 has two modes: FIRST mode and CASSETTE mode. FIRST mode is the default mode for tray 1. In FIRST mode, tray 1

functions as a multipurpose tray. When tray 1 is in FIRST mode, specify the media type and size in the printer driver. The printer looks first for media loaded in tray 1. If the correct width of media is loaded in tray 1, the printer prints from tray 1. If the printer senses that the media in tray 1 is a different size than the media specified in the printer driver, then the printer does not feed the media (to prevent toner residue on subsequent pages).

In CASSETTE mode, tray 1 functions as a regular input tray. When tray 1 is in CASSETTE mode, load media in tray 1 and configure the media type and size in the printer control panel.

Configuring media type and size

Configuring the media type is beneficial for several reasons:

Configuring the media type prevents printing on the wrong (and

possibly more expensive) media. If a user changes the type of media in an input tray, other users

can still print on the correct media. The printer automatically adjusts its print speed to accommodate

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

Note

If the media type is not set correctly , then 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 or excessively slow printing.

Verifying DIMM installation

The printer comes with the following amounts of memory installed in slots 1 and 2:

16-MB DIMMs in the base and N models

32-MB DIMMs in the DN model

In all printer models, slots 3 through 8 are available for additional DIMMs.

The printer supports ROM and synchronous DRAM DIMMs (dual inline memory modules). EDO (extended data out) or Fast Page Mode DRAM DIMMs are not supported.

Figure 15. DIMM slot configuration

DRAM DIMMs must be installed in synchronized pairs: two DIMMs
