HP DesignJet T790 and T1300 Printer Series - Using your printer

The printer will not start
If the printer will not start (the front panel is blank or the diagnostic LEDs are all o), you are recommended to
replace the rmware, in the following way.
1. Go to the Knowledge Center (see Knowledge Center on page 171) and download the rmware.
2. Save the rmware on a USB ash drive. Ideally, the USB ash drive should be empty and formatted with the
FAT lesystem.
3. Ensure that the printer is turned o. Connect the USB ash drive to the Hi-Speed USB host port beside the
front panel, then turn the printer on.
4. The printer takes about a minute to read the rmware le, then asks you to remove the USB ash drive.
5. The printer automatically installs the new rmware and restarts.
The printer does not print
If all is in order (paper loaded, all ink components installed and no le errors), there are still reasons why a le
you have sent from your computer may not start printing when expected:
●
You may have an electrical power problem. If there is no activity at all from the printer, and the front panel
does not respond, check that the power cable is connected correctly and that there is power available at the
socket.
●
You may be experiencing unusual electromagnetic phenomena, such as strong electromagnetic elds or
severe electrical disturbances, which can cause the printer to behave strangely or even stop working. In this
case, turn o the printer using the Power key on the front panel and unplug the power cord, wait until the
electromagnetic environment has returned to normal, then turn it on again. If you still experience
problems, please contact your customer service representative.
●
Nesting may be on (T1300 series only) and the printer is waiting for the specied nest wait time before
calculating the appropriate nests. In this case, the front panel shows the remaining time needed for
nesting.
●
You may have the wrong graphic language setting, see Change the graphic language setting on page 30.
●
You may not have installed in your computer the correct driver for your printer, see the Assembly
instructions.
●
If you are printing on a sheet, you must specify Manual Feed as the paper source in your printer driver.
●
The printer may be holding the job for paper or (T1300 series only) accounting information, see Job status
messages on page 67.
●
You may have requested a print preview (T1300 series only) from your printer driver. This is a function you
can use to check that the image is the one you want. In this case, the preview is displayed on your screen,
and you must click the Print button to start printing.
●
If you are using Mac OS with a USB connection, you may nd that you need to change the data encoding
(PostScript printers only). Press , then , then Setup > Printing preferences > PS > Select encoding
> ASCII. Then congure your application to send ASCII data.
