● 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 173) and request the maintenance kit. The kits are installed by service engineers only. Secure Disk Erase The printer's 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 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 HP's 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 173. 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. 118 Chapter 14 Maintaining the printer ENWW

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

the maintenance kit. The kits are installed by service engineers only.
Secure Disk Erase
The printer's 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 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 HP's free Web-based print
management software: see

.
If you have
difficulty
in using Secure Disk Erase from Web JetAdmin, please contact HP Support: see

.
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.
