HP Designjet T790 and T1300 ePrinter Series - Using your printer

If you need to leave the printer turned off for a long time, follow the additional steps below.
1. Turn off the power using the Power key on the front panel.
2. Also turn off the power switch at the rear of the printer.
3. Disconnect the printer's power cable.
CAUTION: If you turn the printer upside down, ink could escape into the printer and cause serious
damage.
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 off for a six weeks or more, preparing the printheads could take up to 45 minutes.
CAUTION: If the printer remains off 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 firmware
The printer's various functions are controlled by firmware that resides in the printer.
From time to time firmware updates will be available from Hewlett-Packard. These updates increase the
printer's functionality, enhance its features, and may correct minor problems.
IMPORTANT: You are strongly recommended to update the firmware periodically in order to take
advantage of the latest developments.
There are various ways of downloading and installing firmware updates; you can choose whichever
you find most convenient. They can be divided into two categories: automatic and manual updates.
NOTE: The firmware includes a set of the most commonly used paper presets. Extra paper presets
can be downloaded separately; see
Paper presets on page 46.
Automatic firmware updates
Automatic firmware updates are a convenience that is possible with Web-connected printers. Your
printer can automatically download the latest firmware release and install it for you.
