❏ If you are using the USB interface, make sure your cable meets the USB 1.1 or 2.0 standards.
❏ If you are connecting the printer to your computer via a USB hub, connect the printer to the
first-tier hub from your computer. If the printer driver is still not recognized on your computer,
try to directly connect the printer to your computer without the USB hub.
❏ If you are connecting the printer to your computer via a USB hub, make sure the USB hub device is
recognized by your computer.
❏ Turn off the printer and the computer, disconnect the printer's interface cable, then print an
operation check page.
& See "Running a printer operation check" on page 167.
If the check page prints correctly, make sure the printer driver and your application are installed
correctly.

reducing the resolution of your image or printing the image at a smaller size. You may need to
install more memory in your computer.
❏ Uninstall the printer driver, then reinstall it.
