HP DesignJet T790 and T1300 Printer Series - Using your printer

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 o for a
six weeks or more, preparing the printheads could take up to 45 minutes.
CAUTION: If the printer remains o 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 rmware
The printer's various functions are controlled by rmware that resides in the printer.
From time to time rmware updates will be available from HP. These updates increase the printer's functionality,
enhance its features, and may correct minor problems.
IMPORTANT: You are strongly recommended to update the rmware periodically in order to take advantage of
the latest developments.
There are various ways of downloading and installing rmware updates; you can choose whichever you nd most
convenient. They can be divided into two categories: automatic and manual updates.
NOTE: The rmware includes a set of the most commonly used paper presets. Extra paper presets can be
downloaded separately; see Paper presets on page 40.
Automatic rmware updates
Automatic rmware updates are a convenience that is possible with Web-connected printers. Your printer can
automatically download the latest rmware 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 21.
●
To congure automatic rmware updates, you can use the front panel or the Embedded Web Server; see
Set up your Web-connected printer on page 21.
●
If an administrator password has been set, it will be required to change these settings.
●
A rmware 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 rmware 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 rmware updates
Manual rmware 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 rmware is available. If new rmware is available, some
information about the new rmware 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.
