							3.Insert the new printhead into its correct slot in the carriage.
CAUTION:Insert the printhead slowly and vertically, straight down. It may be damaged if you
insert it too fast, or at an angle, or if you rotate it as you insert it.
4.Push down as indicated by the arrow shown below.
CAUTION:When installing the new printhead there may be some resistance, so you need to
press it down firmly but smoothly. You should hear a beep and see confirmation on the front-panel
display that the printhead has been inserted. If you have difficulty, see 
Cannot insert a printhead
on page 183.

							6.Ensure the end of the blue handle catches the wire loop on the near side of the carriage.
7.Lower the handle to rest on the carriage cover.
When all the printheads have been inserted correctly and are accepted by the printer, the printer
beeps.
NOTE:If the printer does not beep when you insert the printhead and the Replace message
appears on the front-panel display, the printhead may need to be reinserted.
8.Close the window.
9.The front-panel display confirms that all printheads are correctly inserted. The printer starts
checking and preparing the printheads. The default routine process, when all printheads are
changed, takes 10 minutes. If the printer finds problems in preparing the printheads, it takes
longer, up to 45 minutes. For a single printhead insertion, the times vary between 2 and 40

							Check printer status
You can check the current status of the printer in various ways:
●If you start the HP Utility and select your printer, you see a page of information describing the
status of the printer and its paper and ink supplies.
●If you access the Embedded Web Server, you see information about the general status of the
printer. The Supplies page in the Main tab describes the status of the paper and ink supplies.
●
At the front panel, you can press 
 for information about paper, ink levels, ink cartridges, and
printheads. If there is a current problem, you are taken automatically to the area with the most
urgent problem.
If there are any current alerts, the upper row of the home screen shows the top-priority alert. Press
the alert message to see a list of all current alerts.
Clean the exterior of the printer
Clean the outside of the printer and all other parts of the printer that you regularly touch as part of
normal operation with a damp sponge or a soft cloth and a mild household cleaner such as non-
abrasive liquid soap.
WARNING!To avoid an electric shock, make sure that the printer is turned off and unplugged
before you clean it. Do not let water get inside the printer.
CAUTION:Do not use abrasive cleaners on the printer.
Maintain the ink cartridges
During the normal lifetime of a cartridge, no specific maintenance is required. However, in order to
maintain the best print quality, replace a cartridge when it reaches its expiration date. The printers
front panel notifies you when any cartridge reaches its expiration date.
You can also check a cartridges expiration date at any time: see 
Check printer status on page 137.
See also 
Handling ink cartridges and printheads on page 125.
Move or store the printer
If you need to move or store the printer, prepare it correctly to avoid possible damage to it. To prepare
the printer, follow the instructions below.
1.Do not remove the ink cartridges or printheads.
2.Make sure that no paper is loaded.
3.Make sure that the printer is idle.
4.Disconnect any cables connecting the printer to a network or a computer.
ENWWCheck printer status

							If you need to leave the printer turned off for a long time, follow the additional steps below.
1.Turn off the power using the Power key on the front panel.
2.Also turn off the power switch at the rear of the printer.
3.Disconnect the printers power cable.
CAUTION:If you turn the printer upside down, ink could escape into the printer and cause serious
damage.
When the printer is turned back on, it takes about three minutes to initialize itself and to check and
prepare the printheads. Preparing the printheads normally takes just over a minute. However, if the
printer has been off for a six weeks or more, preparing the printheads could take up to 45 minutes.
CAUTION:If the printer remains off for a long period of time, the printheads may become unusable.
In this case, you need to replace the printheads with new ones.
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 through lengthy preparation processes before using your printer.
Update the firmware
The printers various functions are controlled by firmware that resides in the printer.
From time to time firmware updates will be available from Hewlett-Packard. These updates increase the
printers functionality, enhance its features, and may correct minor problems.
IMPORTANT:You are strongly recommended to update the firmware periodically in order to take
advantage of the latest developments.
There are various ways of downloading and installing firmware updates; you can choose whichever
you find most convenient. They can be divided into two categories: automatic and manual updates.
NOTE:The firmware includes a set of the most commonly used paper presets. Extra paper presets
can be downloaded separately; see 
Paper presets on page 46.
Automatic firmware updates
Automatic firmware updates are a convenience that is possible with Web-connected printers. Your
printer can automatically download the latest firmware release and install it for you.
Important notes
●Your printer must be connected to the Internet; see 
Set up your Web-connected printer
on page 24.
●To configure automatic firmware updates, you can use the front panel or the Embedded Web
Server; see 
Set up your Web-connected printer on page 24.
●If an administrator password has been set, it will be required to change these settings.
138 Chapter 14   Maintaining the printer ENWW
 
						

							●A firmware update package can be large; you may want to consider whether there are any
implications for your network or Internet connection. Downloads made with a Jetdirect adaptor are
slower than those made with the built-in Ethernet adaptor.
●A firmware update is downloaded in the background: the printer can be printing at the same time.
However, it cannot be installed in the background: printing must stop.
Manual firmware updates
Manual firmware updates can be performed in the following ways:
●Using the Embedded Web Server, select the Firmware update maintenance tab and then
Firmware update. Press Check now to check whether new firmware is available. If new
firmware is available, some information about the new firmware is displayed, and you are given
the opportunity to download and install it.
●Using the HP Utility under Windows, select your printer, the Support tab and then Firmware
Update.
●Using the HP Utility under Mac OS, select Firmware Update in the Support group.
●Using HP Web Jetadmin, with which you can make manual firmware updates or request automatic
updates.
●Using a USB flash drive. Download the firmware file from 
http://www.hp.com/go/T790/
firmware or http://www.hp.com/go/T1300/firmware (according to your printer model) into the
USB flash drive and insert it into the Hi-Speed USB host port beside the front panel. A firmware
update assistant will appear on the front panel to guide you through the update process.
Update the software
To update printer drivers and other software for your printer, go to http://www.hp.com/go/T790/
drivers or http://www.hp.com/go/T1300/drivers.
If your operating system is Windows, HP Software Update regularly offers to update your software
automatically.
Printer maintenance kits
Four maintenance kits are available for your printer, containing components that may need to be
replaced after long use. When one of them is needed, a message is displayed on the front panel and
by the HP Utility.
When you see the message, you should contact HP Support (see 
Contact HP Support on page 203)
and request the maintenance kit. The kits are installed by service engineers only.
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.
ENWWUpdate the software

							Secure Disk Erase provides three 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 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 possible to access fragments of the erased information by using special
tools to detect residual 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 secure. 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
Contact HP Support on page 203.
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.
