Media Selection Guidelines

Note More detailed specifications are in the

on page 31.

Paper

To achieve the best possible print quality and av oid paper jams, f ollo w
these guidelines for selecting paper:

●

Use only copier grade paper that meets all specifications in the
paper 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° F (200° C) for 0.1 second without
deterioration. Do not use paper with a colored coating that was
added after the paper was produced.

●

Pre-printed forms must be printed with non-flammable, heat­resistant 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.

. See “Technical Assistance”

HP LaserJet

Envelopes

CAUTION To prevent severe damage to the printer, do not use envelopes that

have windows, clasps, snaps, or any non-paper materials.

Print Envelopes to the left output bin only.

Envelopes can be printed from Tray 1 and from the optional Envelope
Feeder. Choose envelopes that are well-constructed. They should lie
flat and be sharply creased. They should not be wrinkled, nicked, or
otherwise damaged. Envelope adhesive must be compatible with the
heat and pressure of the fusing process.

C4085-91087 Media Selection Guidelines 11

Adhesive Labels

Use the following guidelines when selecting labels:

CAUTION Tray 1 is required for printing adhesive labels.

Print labels to the left output bin only.
This printer does not support use of labels with any exposed spaces.
Do not attempt to print on label sheets after any of the labels have been

removed from the sheet. Damage to the printer may result.

●

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
damage to the printer.

●

The top sheet (printing surface) must be of copier quality and
provide good toner adhesion.

●

The carrier sheet (backing sheet) must be compatible with the
temperature and pressure of the fusing process, and must be
coated for easy release of the top sheet.

●

The adhesive must be stable at the 392° F (200° C) temperature
encountered for 0.1 second in the fusing process, and must not
produce emissions that exceed exposure le vels or threshold limits
established by OSHA and other saf ety agencies. Adhesives must
not come into direct contact with any part of the printer.

A wide selection of suitable labels may be ordered through Hewlett­Packard. Available sizes are listed in the

Paper Specification Guide

.

HP LaserJet Printer Family

12 Chapter 1 Product Information C4085-91087

Transparencies

CAUTION Tray 1 is required for printing transparencies.

Print transparencies to the left output bin only.
Transparencies used in HP LaserJet printers must be able to

withstand the 392° F (200° C) temperature encountered in the
printer's fusing process for 0.1 second. Suitable transparency film is
available through Hewlett-Packard. See the

Family Paper Specification Guide

for details.

Storing Print Media

Follow these guidelines when stacking and storing print media:

●

Store paper in its wrapper until ready to use.

●

Re-wrap partially used packages of media before storing.

●

Stack each carton upright and squarely on top of the other.

●

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

●

Keep stored media away from temperature and humidity
extremes.

●

DO NOT store cartons or reams directly on the floor where they
will absorb a higher moisture content. Instead, place cartons on a
pallet or on shelves.

●

DO NOT store individual reams in a manner that causes them to
curl or warp along the edges.

●

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

●

DO NOT place anything on top of media, regardless of whether
the paper is packaged or unpackaged.

●

DO NOT store printed documents in vinyl folders (which may
contain plasticizers) or expose the documents to petroleum­based solvents.

HP LaserJet Printer

Shipping Print Media

When shipping print media through different environments, plastic
wrap all cartons on the shipping pallet. When shipping media across
bodies of water, wrap individual cartons as well. Packaging must
protect the media from physical damage.

Hard Disk

The printer hard disk accessory is optional for the HP LaserJet 8000/
N/DN printers. The hard disk is a standard feature of the HP Mopier

240. It can be used to permanently store downloaded fonts and forms
in the printer. Unlike the standard printer memory, permanently
downloaded items remain in the printer even when the printer is
powered off.

Fonts downloaded to the hard disk are available to all users of the
printer.

®

Macintosh users can use the HP LaserJet Utility, and Windows
users can use the HP printer driver to download fonts. The printer
hard disk can also be write-protected through software for additional
security. See the online help associated with your HP software for
more information.

If you are a PostScript language programmer, see Adobe's™
PostScript Language Reference Manual for information about
downloading forms and patterns to the disk. (For the Macintosh
environment, see the online help in the HP LaserJet Utility Guide
included with the HP LaserJet Utility software.) For the Windows
environment, see your HP Windows driver online help.

Determining Memory Requirements

The amount of memory you need depends on the types of documents
you print. With the PCL printer language, the printer can print most
text and graphics at 300 or 600 dpi without additional memory.

Add memory to your printer if you

●

Commonly print complex graphics.

●

Use many downloaded fonts.

●

Print complex documents.

●

Use advanced functions (such as I/O Buffering and Resource
Saving).

You can remove the 8 MB DIMM and add up to 3 64 MB DIMMs for a
total of 192 MB of usable memory.

Table 1-9 presents the amount of memory required for the most
common print jobs performed with the HP LaserJet 8000/N/DN and
HP Mopier 240 using 600-dpi printing.

Service Approach

Repair of the printer normally begins with a three-step process:

●

Step 1: Isolate the problem to the major system, i.e. the host
computer, the network and/or server, or the printer system.

●

Step 2: Determine if the problem is located in the accessories or
in the printer engine.

●

Step 3: Troubleshoot the problem using the procedures in
Chapter 7.

Once a faulty part is located, repair is usually accomplished by
assembly lev el replacement of Field Replaceable Units (FR Us). Some
mechanical assemblies may be repaired at the subassembly level.
Replacement of components on the printed circuit assemblies is not
supported by Hewlett-Packard.

Ordering Parts

Field replaceable part numbers are listed in Chapter 8 of this manual.
Replacement parts may be ordered from HP's Support Materials
Organization (SMO), or Support Materials Europe (SME).

Exchange Program

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

Consumables

The printer has two consumables; the toner cartridge and staple
cartridges, which may be ordered directly from Hewlett-Pac kard. See
Chapter 8 for ordering information.

Toner Cartridge Life

The Toner Cartridge (C3909A) is designed to simplify replacement of
the major “consumable” parts. The toner cartridge contains the
printing mechanism and a supply of toner. HP Mopier 240 cartridges
(C3909S) are packaged in groups of three.

At 5% page coverage, a toner cartridge is guaranteed to print
approximately 15,000 images (see figure 1-7).

Figure 1-7 Sample 5% Page Coverage

C4085-91087 Service Approach 29

The toner cartridge may print less than 15,000 images if routinely
printing very dense print. Conversely, when routinely printing images
with less coverage (such as short memos), or in EconoMode, the
toner cartridge may print more than 15,000 images. However,
EconoMode does not extend toner cartridge component life.

Note For best results, alwa ys use a new toner cartridge before the expiration

date stamped on the toner cartridge box.

Refilled Toner Cartridges & Non-HP Staple
Cartridges

While Hewlett-Packard does not prohibit the use of refilled toner
cartridges and non-HP staple cartridges during the warranty period or
while under a maintenance contract, their use is not supported for the
following reasons:

●

Repairs resulting from the use of refilled toner cartridges and
non-HP staple cartridges are not covered under the Hewlett­Packard warranty or maintenance contract.

●

Hewlett-Packard has no control or process to ensure that a
refilled toner cartridge or non-HP staple cartridge functions at the
high level of reliability of a ne w HP LaserJet toner cartridge or HP
LaserJet staple cartridge. Also, Hewlett-Packard cannot predict
the long term reliability effect on the printer when using different
toner formulations found in refilled cartridges.

●

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-Packard uses a recycling program
for used toner cartridges. Cartridge components that do not wear out
are recycled, as are plastics and other materials. Hewlett-Packard
pays the shipping costs from the user to the recycling plant. For each
cartridge returned, HP donates one U.S. dollar to be shared by the
Nature Conservancy and the National Wildlife Federation. To join this
recycling effort, follow the instructions inside the toner cartridge box.

CFC Usage Class I U.S. Clean Air Act stratospheric ozone-depleting

chemicals (chlorofluorocarbons [CFCs], for example) have been
eliminated from the manufacturing of the printer and packaging.

The printer design reduces:

Energy Consumption Energy usage drops from 500/505 (110V/220V units) watts (W)

during printing to as little as 35/40 (110V/220V units) W while in
low-power (Power Save) mode. This saves energy without
affecting the high performance of the printer. This product
qualifies for the ENERGY STAR Program (U.S. and Japan).
ENERGY STAR is a voluntary program established to encourage
the development of energy-efficient office products. The
ENERGY STAR name is a registered service mark of the U.S.
Environmental Protection Agency.

As an ENERGY STAR partner,
Hewlett-Packard Company has
determined that this product meets
ENERGY STAR Guidelines for
energy efficiency.

Toner Consumption EconoMode uses about 50% less toner, thereby extending the life

of the toner cartridge.

Paper use The printer’s optional duplexing feature, which provides for two-

sided printing, reduces paper usage and the resulting demands
on natural resources.

HP Cartridge Recycling Program information:

Since 1990, the HP LaserJet Toner Cartridge Recycling Program
has collected more than twelve million cartridges that otherwise
may have been discarded into landfills. Once a cartridge is
returned, it is disassembled and reusable components are
cleaned and inspected for quality conformance. After passing
strict inspection procedures, materials such as nuts, screws, and
clips are reclaimed and used to produce new cartridges.
Remaining materials are melted down and used as raw materials
for a variety of other products. Over 95 percent (%) of the weight
of returned materials is recycled. For more information in the
U.S., call (1) [phone] or contact the HP LaserJet Supplies
Website at http://ljsupplies.com/planetpartners. Non-US
customers can call the local HP Sales and Service Office for

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 user’s guide may result in exposure to
hazardous radiation.

Settings and Defaults

The printer makes most printing decisions based on either temporary
settings or factory (permanent) defaults.

Note Settings you send from software applications ov erride printer defaults.

Temporary Settings are the values set for the current print job by

your software application. Temporary settings remain in effect until
the current print job is finished.

Control Panel Defaults are the v alues entered b y selecting a control
panel item and pressing S
indicates that it is now the default. The printer retains default settings
even when power is turned off.

Factory Defaults are the permanent default values for each menu
item set at the factory. These values are listed in table 3-3 on page

56.

ELECT

Printer Driver Information

You can override or change any Printing Menu setting through most
software applications and from the printer driver. When y ou change a
setting from the printer control panel, the new setting becomes the
printer default value.

Paper Source Default

The printer paper source is specified by the print job, not the printer
control panel. The following paragraphs apply when the current job
does not specify a paper source. Unless changed or not specified by
the current job, the software application, or the printer driver, the
paper source default is determined by the “Cold Reset Paper Size”
(letter or A4) set in the Service Mode Menu.

●

If Tray 1 is set to cassette, it will look for the default size.

●

If there is no paper in Tray 1, and Tray 4 is installed and loaded
with the Cold Reset Paper Size, the printer will pull from Tray 4.

●

The printer pulls paper from Tray 5 first if the Optional
2 x 500-sheet Input Tray is installed.

●

If there is no paper in Tray 1, and Tray 4 is not installed, the printer
will pull from the first tray containing the Cold Reset Paper Size.

●

If none of the trays contain the Cold Reset P aper Siz e , the printer
will prompt the user to put letter or A4 paper in Tray 1.

54 Chapter 3 Operating Overview C4085-91087

Resetting the Printer

Cold Reset

Cold Reset clears all data from the printer memory and sets all the
defaults (except Service Mode settings) back to the factory settings.

not recommended. The power save feature does the
following:
Minimizes the amount of power consumed by the printer
when it is idle.
Reduces wear on the printer’s electronic components.
(Turns off the display’s backlight.)
When you send a print job, press a control panel key,
open a paper tray, or open the top cover, the printer
automatically comes out of power save mode.

This item dedicates printer memory to save each
language’s permanent resources. (You might need to
add memory to the printer in order for this item to
appear.) The amount of memory set aside can be
different for each installed language. Some languages
might have memory set aside for resource saving
without requiring all languages to do so. Any time the
amount of memory dedicated to a specific language is
changed, all languages will lose all saved resources,
including any unprocessed print jobs.

OFF

No language resource saving is performed, and
language-dependent resources, such as fonts and
macros, are lost when language or resolution changes.
