Operational problems
Turn off the printer and check the power cord connection between
the printer and the electrical outlet. Then turn the printer back on.
If the electrical outlet is controlled by an outside source such as a
wall switch, make sure the switch is turned on. Try plugging
another electrical device into the outlet to check whether the outlet
is operating properly.
Your computer may not be properly connected to the printer.
Perform the procedure described in “Connecting to the
Computer” in the
Setup Guide .
The interface cable may not be plugged in securely. Check both
ends of the cable between the printer and the computer. If
connecting through the parallel interface, be sure to secure the
connector using the wire retaining clips.
Make sure you use a double-shielded, twisted-pair interface cable
no more than six feet in length.
The developer cartridge may be empty. To replace the cartridge,
see “Replacing the Developer Cartridge” on page 77.
