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 check the Bypass proxy server for local addresses box. Alternatively, for more
precise control, click the Advanced button and add the printer's IP address to the list of exceptions,
for 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 printer's IP address or its domain name to the list of exceptions, for which
the proxy server is not used.
The firmware includes a set of the most commonly used paper profiles. Extra paper profiles can be
downloaded separately; see
Update the software
To update the printer driver and other software for any HP Designjet printer, go to
and select Downloads, then Drivers. Then select your printer, your preferred
language and your operating system.
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 Printer Utility.
When you see the message, you should contact HP Support (see
Contact HP Support on page 186
)
and request the maintenance kit. Three of the kits are installed by service engineers only; the fourth
consists of a replacement cutter, which you can install yourself (see
Replace the cutter on page 126
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.
