HP Designjet T620 Printer series - Manual (Page 105)

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
Paper profiles on page 41 .
Update the software
To update the printer driver and other software for any HP Designjet printer, go to http://www.hp.com/
go/T620/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 Printer Utility.
When you see the message, you should contact HP Support (see Contact HP Support on page 156 )
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 96 ).
