318 Troubleshooting - Avoiding Problems
Checking the printer and computer connection
If you have problems with the printer, the cause may be in the hardware you are using to
connect the printer and computer.
• If you are using a switching device, USB hub or external buffer, discon-
nect the device and connect the printer directly to the computer again. If
you can print normally with the direct connection, contact the manufac-
turer of the device.
• The printer cable may be faulty, or you may be using the wrong type of
cable. Replace the printer cable and try again.
