When you use a printer changer, printer buffer, or a extension

correctly when it is connected to your computer without these
devices.

reinstall the printer driver.
Turn the printer off, open the printer cover and remove the
jammed paper or things that are stuck.

in the Network Guide.

on again, and start printing.

computer are plugged in securely. If the cable is connected
correctly, run a self test as described in "Printing a Self Test" on
page 90.
Use an interface cable that meets the requirements of both the
printer and computer. See "Electronic" on page 109 and your
computer documentation.

application. If necessary, install or reinstall the printer driver
software as described in the supplied setup sheet.
