Installation
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 parallel 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 bidirectional
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.
62
Enhanced I/O (EIO) configuration
LocalTalk I/O
The LocalTalk interface enables you to print directly from a standalone Apple Macintosh computer or from a Macintosh computer on a
LocalTalk network. For specific information on configuring your
computer and printer to print through a LocalTalk interface, refer to
the printer’s getting started guide and the HP JetDirect Print Server
Software Installation Guide

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 example, 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
independently. The two halftone options are Smooth and Details.
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.

Network configuration
Configuring the printer for the network
You can configure certain network parameters on the printer from the
printer control panel or, for most networks, from the HP JetAdmin
Software (or the HP LaserJet Utility for Macintosh). The utilities are
provided on the printing software CD-ROM that comes with the
printer. You can also set these parameters from the HP Web
JetAdmin Software, which is available at http://www.hp.com/go/
webjetadmin.
For a complete list of supported networks and for instructions on
configuring network parameters from software such as HP JetAdmin
and HP Web JetAdmin, see the HP JetDirect Print Server Software
Installation Guide. The guide comes on the
CD-ROM with printers in which an HP JetDirect 600N print server is
installed.
Note
If you are configuring network parameters from the printer control
panel, the control panel menu for configuring parameters appears in
the languages listed below. If your language is not listed, the menu will

Setting network security on the printer
This printer features control panel locking, which allows network
administrators to prevent users from changing certain printer control
panel settings. When a menu is locked, unauthorized users trying to
change settings in the printer control panel will receive the following
message:
ACCESS DENIED
MENUS LOCKED
You can use HP JetAdmin software, the HP LaserJet Utility for
Macintosh, or an ASCII escape sequence to perform this procedure.
For instructions on locking the printer control panel using either the
HP JetAdmin software or the HP LaserJet Utility for Macintosh, see
the online Help for these utilities.

Setting network security on the printer
Locking the control panel
You can prevent users from changing printer control panel settings by
establishing a password and locking the printer control panel. The
control panel offers multiple levels of security. You can lock certain
control panel menus, allowing users to change the rest of the menus,
or you can lock all of the menus—and you can even lock the
[Cancel Job] key. When the printer control panel is locked,
unauthorized users who try to change settings at the control panel
receive the following message:

Using an ASCII PJL escape sequence to
set network security
If you decide to use the ASCII escape sequence, you must use an
MS-DOS® or Windows ASCII editor to create the commands. The
commands must also be sent to the printer by using a DOS COPY
command or an ASCII file download utility. The PJL Technical
Reference Manual is located on CD, part number 5961-0976. Order a
copy of this manual from the HP web site: hp.com.
Note
In the following examples, EC represents the escape character. For
more information on using escape characters, see the PJL Technical
Reference Manual.
To lock or unlock the printer control panel if a password has not
been set, send the following ASCII sequence to the printer:
EC%[email protected] JOB
@PJL DEFAULT CPLOCK=NONE
(or MINIMUM, MODERATE, or MAXIMUM)
@PJL EOJ

To set the password, send the following ASCII sequence to the
printer:
EC%[email protected] JOB
@PJL DEFAULT PASSWORD=[numeric password (0 to
65535)]

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.
72
Cleaning the printer and accessories
Table 4-1
Cleaning the printer
Component
Cleaning Method
Outside covers
Use an HP Toner Cleaning Cloth (part number
5040-3379) or a water-dampened cloth. Do not use
solvents or ammonia-based cleaners.
Inside general
With a dry lint-free cloth, wipe any dust, spilled
toner, and paper particles from the paper path area,
the registration roller, and the toner cartridge cavity.
Paper pickup, feed,
and separation rollers
Use a water-dampened, lint-free cloth.
Separation pad
Use a dry, lint-free cloth.
Registration roller
Use a dry, lint-free cloth.
Transfer roller
Use a dry, lint-free cloth. DO NOT TOUCH the
transfer roller with your fingers.
Fuser
Use a water-dampened, lint-free cloth.
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 transfer 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).

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 varies,
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 for 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 Page 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 for 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 DRUM LIFE LOW message is
displayed. However, when the DRUM LIFE OUT message occurs, the
end of life has been reached and the printer will not operate.
74
Approximate replacement intervals for consumable items
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.

DIMM configuration
You can add additional Random Access Memory (RAM) to this printer
by installing Dual Inline Memory Modules (DIMMs). The printer uses
100-pin, non-parity, synchronous SDRAM memory modules. SDRAM
modules do not need to be configured in pairs (in corresponding left
and right slots).
Note
Extended Data Output (EDO) DIMMs are not supported.
Adding memory
You can install 4, 8, 16, 32, or 64 MB DIMMs into the printer’s three
DIMM slots. The DIMM slots may be used to add memory, fonts, or
firmware upgrades. Note that DIMMs and Single Inline Memory
Modules (SIMMS) are not compatible.
Note
The printer will only recognize up to 208 MB of RAM. Additional memory
will not be used by the printer.
Installing memory in the printer requires the removal of the formatter
board from the rear of the printer. To remove the formatter board, you
must unscrew 6 screws, as shown here. The DIMMs are then inserted
into the available slots in the formatter board. See Appendix A in the
online user guide for installation instructions.

DIMM configuration
CAUTION
Do not attempt to remove the DIMM in slot #4 (see Figure 4-5). The
DIMM in slot #4 is part of the printer’s firmware. Removing it will affect
printer operation.
Figure 4-5
Do not remove the DIMM in slot #4.
CAUTION
The HP Color LaserJet 4500 printer uses 100-pin, non-parity,
synchronous SDRAM DIMMs. Extended Data Output (EDO) DIMMs
are not supported. To ensure you are using the correct DIMM, see the
differences below.

Non-volatile memory (NVRAM)
The printer uses NVRAM to store I/O and information on the print
environment’s configuration. The contents of NVRAM are retained
when the printer is deactivated or disconnected. There is one NVRAM
on the formatter and one on the DC controller.
