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 190)
and request the maintenance kit. The kits are installed by service engineers only.
Secure Disk Erase (T770 HD and T1200 series only)
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.
