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 p oint that the printer breaks down, the printer keeps
track of the number of cycles that the printer carri age makes across the axis of the printer, and also
monitors the total quantity of ink used.
The printer uses these numbers to  track the need for preventive main tenance, and displays one of the
following messages on the front panel:
● Maintenance #1 required
● Maintenance #2 required
These messages mean that some components are  nearing the end of their lives. You can continue
printing for quite some time, depe nding on your use of the printer. However, HP strongly recommends
that you contact your customer service representati ve 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.
ENWW Maintain the ink cartridges

Maintain the printer
 
						

							The benefits of arranging a service engineers visit when these messa ges appear on the front panel are
two-fold:
● The printer components can be replaced at a time
 that 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 period 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 ca
rriage 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 
connect the printer to a network, a computer, or
a scanner.
NOTE: If the printer or ink cartridges are moved from a cold location to a warm and humid location,
water from the atmosphere can condensate on the pr inter parts and cartridges and can result in ink
leaks and printer errors. In this case, HP recommends that you wait  at least 3 hours before turning on
the printer or installing 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 al ways on or in sleep mode, whenever possible, to maintain the
health of the printheads. In both cases, the prin ter wakes up from time to time to maintain the
printheads. Thus you can avoid going through length y preparation processes before using your printer.
Update the printer firmware
The printers various functions are controlled by software that resides in the printer, also known as
firmware.
From time to time, firmware upda tes from Hewlett-Packard become  available. These updates increase
the printers functionality  and enhance its features.
Firmware updates can be downloaded from the Intern et and installed in your printer in the following
ways. Use the method that you find most convenient.
● In Windows, open the HP Utility,  select your printer, click the Support tab, and then select
Firmware Update .
● In Mac OS, open the HP Utility, select  Support and then select Firmware Update.
● Through the printers Embedd ed Web Server, click the Setup tab and then select  Firmware
update .
144 Chapter 13   Maintain the printer ENWW
Maintain the printer
 
						

							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 commonl y used paper presets. Extra paper presets can be
downloaded separately; see 
Download paper presets on page 37 .
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 pr ecise control, click the Advanced button and add the printers IP
address to the list of exceptions, fo r which the proxy server is not used.
● In Safari for Mac OS, go to  Safari > Preferences  > Advanced  and click the Proxies:
Change Settings button. Add the printers IP address or its domain name to the list of
exceptions, for which the proxy server is not used.
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 information 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 difficult for most people to access, but may be
accessed using software designed 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 er ased, and the information itself is also
overwritten with a fixed character pattern. This meth od 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 Secure Disk Erase  from Web JetAdmin, please contact HP Support. See
HP Customer Care on page 180.
NOTE: If you choose to erase the whole hard disk, you may be asked to restart the printer several
times during the process, which will take about 6 hours with Secure Disk Erase or 24 hours with Secure
Sanitizing Erase.

							General advice
Use the following approach when you have any print-quality problem:
●To achieve the best performance from your printe
r, use only genuine HP supplies and accessories,
whose reliability and performance have been thor oughly tested to give trouble-free performance
and best-quality prints. For deta ils of recommended papers, see 
Order paper on page 39.
● Make sure that the paper type that
 you select on the front panel is the same as the paper type that
is loaded in the printer. Make su re that the paper type has been calibrated. Also make sure that
the paper type that you select in your software  is the same as the paper type that you loaded in
the printer.
CAUTION: If you have the wrong paper  type selected, you might expe rience poor print quality
and incorrect colors, and damage to the printheads might occur.
● Make sure that you are using the most appropri
ate print-quality settings for your purposes. See
Select print quality on page 79. You are likely to see lower prin t quality if you have moved the
print-quality slider to the  Fast end of the scale, or set  the custom quality level to  Fast.
● Make sure that your environmental conditions (temperature, humidity) are in the recommended
range. See 
Environmental specifications on page 203
.
● Make sure that your ink cartridges and printheads have not passed their expiration dates. See
Maintain the ink cartridges on page 143
.
● Avoid touching the paper while printing is in progress.

If the problem persists despite all the above actions,  contact your customer service representative for
further support.
Lines appear stepped or jagged
If lines in your image appear st epped or jagged when printed:
1.The problem may be inherent in the image. Try to
 improve the image with the application you are
using to edit it.
2. Check that you are using appropriate print-quality settings. See 
Print options on page 77.
3. Select the custom print-quality options  in the driver dialog, and turn on the Maximum detail
option (if available).
Lines print double or in the wrong colors
This problem can have va rious visible symptoms:
● Colored lines are printed do
uble, in different colors.

							●The borders of colored blocks are wrongly colored.
To correct this kind of problem:
1.Reseat the printheads by removing 
them and then reinserting them. See 
Remove a printhead
on page 51 and Insert a printhead on page 54.
2. Align the printheads. See 
Align the printheads on page 59

							Humidity can cause ink to soak into the paper, making the lines blurred and fuzzy. Try the following:
1. Check that your environmental conditions (tempe
rature, humidity) are suitable for high-quality
printing. See 
Environmental specifications on page 203 .
2. Check that the paper type selected in the front pa
nel is the same as the paper type you are using.
To check on the front panel, use the  View information key 
.
3. Try changing to a heavier paper type, such as
 HP Heavyweight Coated Paper or HP Super
Heavyweight Plus Matte Paper.
4. Select a paper type that is slightly thinner than 
the paper you have loaded; this will persuade the
printer to use less ink. Here are some example paper types in ascending order of thickness: Plain
Paper, Coated Paper, Heavyweight Coated  Paper, Super Heavyweight Plus Matte Paper.
5. If you are using glossy paper, try changi
ng to a different type of glossy paper.
6. Align the printheads. See 
Align the printheads on page 59
.
Line lengths are inaccurate
If you have measured your printed  lines and find that the lengths are not sufficiently accurate for your
purposes, you can try to improve line le ngth accuracy in the following ways.
1. Print on HP Matte Film, for which your printe
rs line length accuracy is specified. See 
Functional
specifications on page 201.
Polyester film is about ten times more dimensionally stable than paper. However, using film that is
thinner or thicker than HP Matte Film  will reduce line length accuracy.
2. Set the Print Quality slider to  Quality.
3. Maintain the room at a steady temperat
ure between 10 and 30°C (50 and 86°F).
4. Load the roll of film and let it re
st for five minutes before printing.
5. If you are still not satisfied, try 
recalibrating the paper advance. See 
Perform paper advance
calibration on page 35.
