							Lubricate the printhead carriage
The printhead carriage occasionally (about once a year) needs lubrication so that it continues to slide
easily along the slider rod.
1 .
To gain access to the carriage, go to the front panel and select the 
 icon, and then select  Replace
printheads . The carriage slides to the  middle section of the printer.
CAUTION:If the carriage remains in the central part  of the printer for more than 7 minutes,
it attempts to return to its home position on the right.
2 . Take the bottle of oil from the Maintenance Kit that
 is supplied with your printer. A replacement kit
can be ordered if necessary.
3 . Open the printer window and apply a few drops of th
e oil to the pads on either side of the carriage.
4. Apply a few drops of oil directly to the slider rod on either side of the carriage.
5
. Close the printer window.
Maintain the ink cartridges
During the normal lifetime of a cartridge, no spec
ific maintenance is required. However, in order to
maintain the best print quality, you should replace a cartridge when it has reached its expiration date,
which is the manufacturing date marked  on the cartridge plus 30 months.
Perform preventive maintenance
During the life of your printer, componen ts that are used constantly can wear out.
To avoid having these components degrade to the po int that the printer breaks down, the printer keeps
track of the number of cycles that the printer carr iage makes across the axis of the printer, and also
monitors the total quantity of ink used.

Maintain the printer
 
						

							The printer uses these numbers to track the need for preventive maintenance, and displays one of the
following messages on the front panel:
●Maintenance #1 required
● Maintenance #2 required
These messages mean that some comp onents are nearing the end of their lives. You can continue printing
for quite some time, depending on  your use of the printer. However, HP strongly recommends that you
contact your customer  service representative and arrange for a  preventive maintenance visit. The service
engineer can then replace the worn parts onsite , which will prolong the life of the printer.
The benefits of arranging a service engineers visit when these messages appear on the front panel are
two-fold:
● The printer components can be replaced at a time th
at is convenient for you, and so will not disturb
your daily workflow.
● When the service engineer performs a preventive maintenance visit, replaces several parts at once.
This eliminates the need for repeat visits.
Move or store the printer
If you need to move 
your printer or store it for an extended pe riod of time, prepare it correctly to avoid
possible damage.
1 . Do not remove the ink cartridges, printheads, or printhead cleaners.
2 . Make sure that no paper is loaded.
3 . Make sure that the printhead carriage is located in 
the service station (at the right end of the printer).
4 . Make sure that the  Ready message appears on the front panel.
5 . Turn off the power by using the 
Power button on the front panel.
6 . Also switch off the power switch at the rear of the printer.
7 . Disconnect the power cable and any cables that co
nnect the printer to a network, a computer, or a
scanner.

							8. If you have a take-up reel installed, remove the ta
ke-up reel sensor and cable-housing unit from the
foot of the printer stand. For yo ur convenience, you can place the  sensor and cable-housing unit on
the printer-stand crossbar and use the blue, plastic  screw to affix the housing unit to the leg of the
stand, while you move the printer.  (See the following graphic.) When  reinstalling the housing unit,
make sure that the wheel on the foot of  the printer stand is pointing forward.
NOTE:If the printer or ink cartridges are moved from a cold location to a warm and humid
location, water from the atmosphere can conden sate on the printer parts and cartridges and
can result in ink leaks and prin ter errors. In this case, HP recommends that you wait at least
3 hours before turning on the printer or instal ling the ink cartridges, to allow the condensate
to evaporate.
TIP: Because preparing and purging the printheads  uses both time and ink, you are strongly
recommended to leave the printer always on or in sleep mode, whenever possible, to maintain
the health of the printheads. In both cases, the  printer wakes up from time to time to maintain
the printheads. Thus you can avoid going throug h lengthy preparation processes before using
your printer.
Update the printer firmware
The printers various functions are controlled by so ftware that resides in the printer, also known as
firmware.
From time to time, firmware updates  from Hewlett-Packard become available. These updates increase the
printers functionality an d enhance its features.
Firmware updates can be downloaded fr om the Internet and installed in your printer in the following ways.
Use the method that you find most convenient.
● In Windows, open the HP Easy Printer Care, select your printer, click the  Support tab, and then
select  Firmware Update .
● In Mac OS, open the HP Printer Utility, select  Support and then select Firmware Update .
● Through the printers Embedded Web Server, click the  Setup tab and then select Firmware
update .
Follow the onscreen instructions to download the firmware  file and store it on your hard disk. Then select
the downloaded file and click  Update.
The firmware includes a set of the most commonly  used paper profiles. Extra paper profiles can be
downloaded separately; see 
Download paper profiles on page 47.

							If you experience very slow progress while uploading the firmware file to the printer, the reason could be
that you are using a proxy server. In that case, try bypassing the proxy server and accessing the Embedded
Web Server directly.
● In Internet Explorer 6 for Windows, go to  Tools > Internet Options > Connections  > LAN
Settings , and select the Bypass proxy server for local addresses  check box. Alternatively,
for more precise control, click the  Advanced button and add the printers IP address to the list of
exceptions, for which the proxy server is not used.
● I n  S a f a r i  f o r  M a c  O S ,  g o  t o  Safari  > Preferences > Advanced and click the  Proxies: Change
Settings  button. Add the printers IP address or its doma in name to the list of exceptions, for which
the proxy server is not used.
Change the ink absorber
An alert appears on the printer front panel when the  ink absorber is reaching its maximum saturation and
again when the absorber should be changed.
NOTE: The absorber can become excessively dry and fail to function correctly in climates where
the relative humidity is  consistently below 25%.
CAUTION:A saturated or excessively  dry ink absorber can cause severe damage to the
printheads and other parts of the printer. HP st rongly recommends that you promptly change the
ink absorber when alerted.
Remove the ink absorber
1 . Find the ink absorber and disposable plastic glov
es that are included in the maintenance kit that
came packaged with your printer.
2 .
On the printers front panel, select the 
 icon, and then select  Replace maintenance ctg.
3 . Open the printer window.

Secure disk erase
The printers hard disk is used as a temporary storage area for print jobs. The Secure Disk Erase facility
can completely erase your informatio n from the hard disk to protect it from unauthorized access. You can
choose to erase particular files, or the whole hard disk.
Secure Disk Erase provides thre e different levels of security:
● Non-Secure Fast Erase : all pointers to the information are  erased. The information itself remains
on the hard disk until the disk space it occupies is needed for other purposes, and it is then
overwritten. While it remains on the disk, it is diffi cult for most people to access, but may be accessed
using software design ed for the purpose. This is the normal  method in which files are erased on most
computer systems; it is the fastest method but the least secure.
● Secure Fast Erase : all pointers to the information are erased, and the information itself is also
overwritten with a fixed character pattern. This method is slower than Non-Secure Fast Erase, but
more secure. It may still be possib le to access fragments of the erased information by using special
tools to detect residu al magnetic traces.
● Secure Sanitizing Erase : all pointers to the information are erased, and the information itself is
repetitively overwritten using an algorithm designed to eliminate any residual traces. This is the
slowest method, but the most secu re. Secure Sanitizing Erase meets the US Department of Defense
5220-22.m requirements for clearing  and sanitization of disk media. This is the default security level
when using Secure Disk Erase.
Secure Disk Erase is one of the facilities provided  by Web JetAdmin, which is HPs free Web-based print
management software. See 
http://www.hp.com/go/webjetadmin/ .
If you have difficulty in using Se cure Disk Erase from Web JetAdmin , please contact HP Support. See 
HP
Customer Care on page 183.
NOTE: If you choose to erase the whole hard disk, yo u may be asked to restart the printer several
times during the process, which  will take about 6 hours with Secu re Disk Erase or 24 hours with
Secure Sanitizing Erase.
