Cause: The USB cable was connected before the software was installed. Connecting the USB
cable before you are prompted can cause errors.
After setting up the product, it does not print
Solution: If the product and computer are not communicating with each other, try the following:
• Look at the On light located on the product. If it is not lit, the product is turned off. Make sure
the power cord is firmly connected to the product and plugged into a power outlet. Press
the On button to turn on the product.
• Make sure the print cartridges are installed.
• Make sure you have paper loaded in the input tray.
• Check that the product 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 product off and
then turn it on again.
• Check that the product 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.
• Check the connection from the product to your computer. Verify that the USB cable is
securely plugged into the USB port on the back of the product. 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 product off and then on again.
• If you are connecting the product 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 product off and then on again.
• If the product is offline, turn the product off and on again. Start a print job.
• If necessary, remove and then install the software you installed with the product again.
