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. Press the power key for 5 seconds to reset the printer.
● 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, contact HP Support: see Contact HP Support on page 193.
● Nesting may be on, and the printer is waiting for the specied 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 22.
● 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 Single sheet as the paper source in your printer driver.
● The printer may be holding the job for paper or accounting information, see Job status messages
on page 85.
● You may have requested a print preview 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.
Front panel fails to initialize
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 HP Support Center (see HP Support Center on page 192) 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.
Printer seems slow
Here are some possible explanations:
● Did you set the print quality to Best or Maximum detail? Best-quality and maximum detail prints take
longer.
● Did you specify the correct paper type when loading the paper? Some paper types require more time for
printing; for example, photo and coated papers require more drying time between passes. To nd out the
printer's current paper type setting, see View information about the paper on page 35.
