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 (Windows) or stopped (Mac). 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.
● Check the USB cable. If you are using an older cable, it might not be working properly.
Try connecting it to another product to see if the USB cable works. If you experience
problems, the USB cable might need to be replaced. Also verify that the cable does
not exceed 3 meters (9.8 feet) in length.
● Make sure your computer is USB ready. Some operating systems, such as Windows
95 and Windows NT, do not support USB connections. Check the documentation that
came with your operating system for more information.
● Check the connection from the HP All-in-One to your computer. Verify that the USB
cable is securely plugged into the USB port on the back of the HP All-in-One. Make
sure the other end of the USB cable is plugged into a USB port on your computer.
After the cable is connected properly, turn the HP All-in-One off and then on again.
● If you are connecting the HP All-in-One through a USB hub, make sure the hub is
turned on. If the hub is on, try connecting directly to your computer.
● Check other printers or scanners. You might need to disconnect older products from
your computer.
● Try connecting the USB cable to another USB port on your computer. After you check
the connections, try restarting your computer. Turn the HP All-in-One off and then on
again.
● If the HP All-in-One is offline, turn the HP All-in-One off and on again. Start a print job.
● If necessary, remove and then install the software you installed with the HP All-in-One
again.
