HP Sales and Service Office for further instructions.

HP cartridge recycling program information:

Since 1990, the HP LaserJet Toner Cartridge Recycling Program has
collected more than twelve million cartridges that otherwise would
have been discarded into landfills or similar facilities. This rapidly
growing program returns used cartridges to the manufacturing
process, thus conserving a variety of resources. Once a cartridge is
returned through the prepaid return program, it is disassembled. The
reusable components and the plastic housing 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, like the
photoconductive drum, are melted down and used as raw materials
for a variety of other products. By the w eight of the materials returned,
over 95 percent (%) are recycled. All HP LaserJet Toner Cartridges
are shipped in recycled boxes with the entire box being recyclable
through the returns program. Styrofoam end caps, which were used
to support HP LaserJet Toner Car tridges during shipping, have been
replaced with molded end caps made from 100% post-consumer
paper products. For more information in the U.S., call
(1) [phone] or visit the HP LaserJet website at
http://www.ljsupplies.com/planetpartners. International customers
can call the local HP Sales and Service Office for further information

Safety 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. 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 Saf ety 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.

Material Safety Data Sheet

The Toner Cartridge/Drum Material Safety Data Sheet (MSDS) can
be obtained by calling the U.S. HP FIRST at [phone], or by
visiting the website at http://www.ljsupplies.com/planetpartners/
datasheets.html. International customers should see support
information in this guide for appropriate phone numbers and

Hint To get documents from HP FIRST by fax, use a group 3 (touch tone)

fax machine.

Toner safety

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

Chapter 2 Service approach 31

Service approach

Printer repair normally begins by using the printer’s internal
diagnostics and the three-step process below:

Step 1 Isolate the problem to the major system (for example, 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, the printer can usually be repaired at the

assembly level by replacing field replaceable units (FRUs). Some
mechanical assemblies may need to be repaired at the subassembly
level. Hewlett-Packard does not support replacement of components
on the printer circuit assembles.

Using the parallel cable

The printer can connect to the computer with a bidirectional parallel
cable (IEEE-1284C compliant) (see Figure 3-2). Connect the male
“C” connector to the printer and the male “B” connector to the
computer. HP recommends that the par allel cable length be no longer
than 10 meters (30 ft) in length. The cable (HP part number C2946A)
is included with the HP Color LaserJet 4500 printer. It must be
purchased separately for the HP Color LaserJet 4500 N and DN
printers.

Figure 3-2 Parallel cable with a “C” connector

Parallel interface

When used to describe a parallel interface, the term
indicates that the printer is able to both receive data from the
computer and to send data to the computer through the parallel port.

Note To use the enhanced capabilities of the bidirectional parallel interface

such as bidirectional communication between the computer and
printer, faster transfer of data, and automatic configuration of printer
drivers, your software application must support these capabilities.

When you are using multiple ports, you can adjust automatic I/O
switching to maximize performance by using the timeout feature. If
data from other ports appears in the middle of your print job, increase
the I/O timeout value.

Enhanced I/O (EIO) configuration

This printer comes equipped with two enhanced input/output (EIO)
slots. These slots hold compatible external devices such as the
HP JetDirect 600N Print Server. Plugging EIO cards into the slots
increases the number of network interfaces available to the printer.

EIO cards can maximize printer performance when you are printing
from a network. In addition, they provide the ability to place the printer
anywhere on a network. This eliminates the need to attach the printer
directly to a server or a workstation and enables you to place the
printer closer to your network users.

The printer control panel will have an additional menu (EIO Menu) if
the printer is configured with EIO cards. (See the chapter on using the
printer control panel in the online user guide.)

Note Installation of cards and network configuration should be performed by

a network administrator.

HP JetDirect print servers

HP JetDirect print servers (network cards) can be installed in one of
the printer EIO slots. These cards support multiple network protocols
and operating systems. HP JetDirect print servers facilitate network
management by allowing you to connect a printer directly to your
network at any location. HP JetDirect print servers also support the
Simple Network Management Protocol (SNMP), which provides
network managers with remote printer management and
troubleshooting through HP JetAdmin software.

Chapter 3 Installation and configuration 63

Printer drivers

The optimal way to control the printer is through settings in a software
application or through the printer driver. Changing print settings via a
software application affects only that particular print job. Most
software applications allow you to choose print settings from menus
within the application. Software application settings and printer driver
settings override the settings on the printer control panel.

For best print quality, always select the paper or media type in the
printer driver. Different media types use different printer settings. For
example, selecting transparencies in the driver causes the printer to
use a different color table , one designed for maximum print quality on
transparencies. Additionally, transparencies cause the printer to
adjust printer speed and fuser temperature.

Other media types affect the printer settings as well: Selecting heavy
or glossy media, for e xample, causes the printer to change the engine
speed.

The printer driver also gives you customized control of color text,
graphics, and photos. The following color control features are
available only through your HP printer driver:

Halftone Options



 HP ColorSmart II

Halftone options affect the resolution and clarity of your color output.
You can select halftone settings for text, graphics, and photos

HP ColorSmart II default settings will produce optimum results for
most color printing needs. However, you can also manually adjust
color settings through the printer driver’s Vivid Color and Screen
Match color control options.

See the printer driver’s online Help for details on color settings and
their effect on printed output.

Cleaning the printer and accessories

To maintain high print quality and performance, use the following
opportunities to thoroughly clean the printer and the paper handling
accessories:

every time you change the toner cartridge (run a few pages



through)

 after printing approximately 5,000 pages for C (cyan),

M (magenta), and Y (yellow); and 8,000 pages for K (black)
whenever print quality problems occur



Clean the outside surfaces with a lightly water-dampened cloth.
Observe the warning and caution below.

WARNING! Before you begin these steps , turn the printer off and unplug all power

cords to avoid shock hazard.
Be careful when cleaning around the fusing assembly area. It may be

hot.

CAUTION To avoid permanent damage to the toner cartridge, do not use

ammonia-based cleaners on or around the printer.
Do not touch the transfer roller. Skin oils on the roller can reduce print

quality. If toner gets on your clothes, wipe it off with a dry cloth and
wash your clothes in cold water. Hot water sets toner into fabric.

Cleaning spilled toner

Defective toner cartridges can develop leaks. Also, after a paper jam
has occurred, some toner may remain on the rollers and guides
inside the printer. The pages that print immediately after the jam may
pick up this toner.

CAUTION When cleaning the printer, do not touch the transf er roller with the damp

cloth or with your fingers.

Vacuum specifications

Do not vacuum the printer or any spilled toner using a conventional
vacuum. Toner particles used in this product may be too fine for
effective vacuuming and could result in damage to conventional
vacuums.

A vacuum specifically designed for cleaning toner may be used if it is
capable of filtering fine particles (5 microns in diameter).

Approximate replacement intervals for consumable items

Imaging drum life

Images versus pages

The life of the imaging drum (25K) is stated in terms of Letter/A-4-size
images. The number of images printed for each sheet of paper v aries,
depending on the mix of color, type of format, and whether duplexing
has occurred. The following guidelines will help determine drum life:

 An “image” is a layer of toner. An A-4/Letter-size color page

printed on one side contains four A-4/Letter images, one f or each
color (CMYK).

 A duplexed sheet counts as two pages. In color duplex mode

(printing on both sides of a page), there are eight A-4/Letter-size
images per A-4/Letter sheet.

The page count numbers on the Configuration P age give a count



of the number of pages printed, regardless of size. For example,
an A-4-size color duplexed page takes eight images to print, but
only adds two pages to the page count.

Usage patterns

How the printer is actually used can also have a significant effect on
drum life:

 Because of pre- and post-rotations, the drum wear is

approximately the same f or a one-page job as for a two-page job .
Frequent short jobs will decrease the drum life.

There are extra rotations and cleaning cycles when printing



duplex pages. Duplex jobs use the imaging drum at a higher rate
than comparable simplex jobs.

“Drum life low” versus “drum life out”

The DRUM LIFE LOW warning message on the control panel indicates
approximately 20% of life remaining. This is intentional to allow the
user enough time to order a replacement kit (C4195A). It is perfectly
acceptable to continue to print while the
displayed. Ho w ever, when the
end of life has been reached and the printer will not operate.

74 Approximate replacement intervals for consumable items

DRUM LIFE LOW

message is

Key points to remember

 The drum life specification assumes two-page jobs, one-sided

printing on A-4/Letter-size pages. When printing in color (4

images per page), the number of pages will be 1/4 of the images

printed.

Due to the carousel arrangement of the color cartridges, color



printing uses four images per page even if only one color is

actually used.
