Media Selection Guidelines

NOTE

More detailed specifications are in the HP LaserJet Printer Family Paper Specification Guide, HP Part No. 5002-1801 (See “R elate d Docum en t at ion

and Training Media” later in this chapter).

Paper

To achieve the bes t po ssible p rint quality and avoid pape r jams , follow these guidelines for selecting paper:

• Use only copier grade paper that meets all specificat io ns in the pap er

specification guide. Avoid paper with embossed lettering, perforations, or texture that is too smooth or too rough.

• Colored paper should be of the same high quality as white photocopy paper.

The pigments must withstand the fusing temperature of 392°

0.1 second with out det er ioration. Do not use pap er with a colo r ed co at in g that was added after the paper was produced.

F (200° C) for

• Pre-printed forms must be print ed wit h no n- flam mable , heat- resis t ant inks

that do not melt, vaporize, or release hazardous emissions when subjected to the fusing temperature of 392° F (200° C) for 0.1 second.

•

A small sample of a new print media should be tested before purchasing large quantities.

Envelopes

CAUTION To prevent severe printer damage, do not use envelopes having windows,

clasps, snaps, or synthetic materials.

Envelopes can be print ed only from the MP Tray. Choose envelope s that are well-constructed. They shou ld lay flat and be shar p ly c rease d. They should not be wrinkled, nicked, or otherwise damaged. Envelope adhesive must be compatible with the heat and pressure of the fusing process.

1-8 Product Information

Adhesive Labels

Product

Information

Use the following guidelines when selecting labels:

CAUTION

This printer does not support use of labels with any exposed spaces. Previous LaserJet family printers could safely print on label stock with exposed spaces running lengthwise down the sheet.

Do not attempt to print on label she ets af ter any of the labels have be en removed from the sheet . Damage t o the pri n ter may res ult .

• Labels must be arranged on the carrier sheet so that there are no exposed

spaces on the sheet. Using label stock with spaces between rows or columns of labels can often result in labels peeling off during printing, causing serious jamming and possible printer damage.

• The top sheet (printing surface) must be of copier quality and provide good

toner adhesion.

• The carrier sheet (bac k ing she et) mus t be c omp at ible wit h t he tem per at u r es

and pressure of the fusing process, and must be coat ed for easy rele ase of the top sheet.

• The adhesive must be stable at the 392° F (200° C) temperatures

encountered for 0.1 second in the fusing process, and must not produce emissions that exceed exposur e le ve ls or thre s hold limits establis he d by OSHA and other safety agencies. Adhesives must not come into direct contact with any part of the printer.

NOTE The MP Tray is recommended for printing adhesive labels.

A wide selection of suitable labels is available through Hewle t t-Pa ckar d. A list of available sizes is located in the HP LaserJet Printer Family Paper Specification Guide, HP Part No. 5002-1801.

Transparencies

Overhead transparencies used in HP LaserJe t printers must be able to withstand the 392° F (200° C) temperatures encountered in the printer’s fusing process for 0.1 second. Suitable transparency film is available through Hewlett-Packard. Refer to the HP LaserJet Printer Family Paper Specification Guide, HP Part No. 5002-1801 for details.

NOTE The MP Tray is recommended for printing transparencies.

Product Information 1-9

Storing Print Media

Follow these guidelines when stacking and storing print med ia:

• Store paper in its ream wrapper until ready to use.

• DO NOT store cartons or reams directly on the floor where they will absorb

a higher moisture content. Instead , place cart ons on a pallet or on shelv es.

• DO NOT store individual reams in a manner that causes them to curl or

warp along the edges.

• Re-wrap partially used packages of media before storing.

• DO NOT stack more than six cartons on top of each other.

• Stack each carton upright and squarely on top of the one underneath.

• DO NOT place anything on top of media, regard less of whet he r the paper is

packaged or unpackaged.

• Store envelopes in a protective box to avoid damaging the envelope edges.

• Keep stored media away from temperature and humidity extremes.

• DO NOT store printed documents in vinyl folders (which may contain

plasticizers) or expose the docu ment s to petrole um base d solvent s.

Shipping Print Media

When shipping prin t media th rough dif ferent envir onm ents, plastic wrap all cartons on the shipping palle t. When shipp ing media across bod ies of water, wrap individual car ton s as well. Pac kagin g mus t protect the medi a from physical damage.

Service Approach

Repair of the printer normally beg ins wit h us e of the printer ’s int ern al diagnostics in conjunction with the troubleshooting procedures in Chapter 7. Once a faulty part is located, repair is generally accomp lished by assembly level replacement of Field Replaceable Unit s (FRUs). Some mechanic al assemblies may be repaired at the subassembly level. PCA compone nt replacement is not supported by Hewlett-Packard.

Ordering Parts

Field replaceable part numbers are found in Chap ter 8 of this manual. Replacement parts may be ordered from HP’s Service Materials Organization (SMO), or Support Materials Europe (SME).

Phone numbers for the various sources are:

• SMO (Service Materials Organization)

1-800-227-8164 (U.S. only)

• SME (Support Materials Europe)

(49 7031) 142253

• HP’s Distribution Center (HPD)

1-303-353-7650

Exchange Program

HP offers remanufactured assemblies for some parts. These are ident ified in Chapter 8 and can be ordered through Parts Direct Ordering (PDO), or Support Materials Europe (SME).

Consumables

The printer has no consumables other than the toner cart ridge, which may be ordered directly from Hewlett-Packard. Refer to Chapter 8 for ordering information.

1-16 Product Information

Toner Cartridge Life

The toner cartridge (C3900A) is designed to simplify replacement of the major “consumable” parts. The toner cartridge contains the printing mechanism and a supply of toner.

At 5% page coverage, a toner cartrid ge will pri n t approximat ely 7500 p ages (see Figure 1-7).

Sample 5% Page Coverage

When regularly printin g pag es wit h less cover age , such as sho rt memo s, a toner cartridge should print more th an 7 500 page s . However, the cart rid ge may print less than 7500 pages if routinely printing very dense print.

NOTE For best results, always use a toner cartrid ge be fore the expir at io n d at e

stamped on the toner cartridge box.

Product Information 1-17

Refilled Toner Cartridges

While Hewlett-Pack ar d does not prohibit the use of refilled toner car trid ge s during the warranty period or while under a maintenance contract, their use is not recommended for the following reasons:

• Repairs resulting from the use of refilled tone r car trid ges ar e not covered

under the Hewlett-Packard warranty or maintenance contract.

•

Hewlett-Packard has no control or process to ensure that a refilled toner cartridge functions at th e high lev el of reliability of a new HP LaserJet toner cartridge. Hewlett-Packard also cannot predict what the long term reliability effect on the printer is from using different toner formulations found in refilled cartrid ges.

• The print quality of HP LaserJet toner cartridges influences the customer’s

perception of the printer. Hewlett-Packard has no control over the actual print quality of a refilled toner cartridge.

Recycling Toner Cartridges

In order to reduce waste, Hewlett -Pac kar d ut ilize s a recycling progr am fo r used toner cartridges. Cartridge components that do not wear out are recycled. Plastics and other materials are recycled. Hewlett-Packard pays the shipping costs from the user to the recycling plant. For each cartrid ge returned, HP don a te s one U .S. d ollar t o be shared by the Nature Conservancy and the National Wildlife Federation. To join this recycling effort, follow the instructions inside the toner cartridge box.
