Communication problems over a USB connection
If the HP All-in-One and computer are not communicating with each other, try the
following:
• Make sure the print cartridges are installed.
• Make sure you have paper loaded in the input tray.
• Check that the HP All-in-One does not have a paper jam.
• Check that the print carriage is not jammed.
Open the print cartridge door to access the print carriage area. Remove any objects
that are blocking the print carriage, including any packing materials. Turn the HP All-
in-One off and then turn it on again.
• Check that the HP All-in-One print queue is not paused. If it is, choose the appropriate
setting to resume printing. For more information about accessing the print queue, see
the documentation that came with the operating system installed on your computer.
• Look at the On button located on the top of the HP All-in-One. If it is not lit, the HP All-
in-One is turned off. Make sure the power cord is firmly connected to the HP All-in-
One and plugged into a power outlet. Press the On button to turn on the HP All-in-
One.
