Turn off the printer and check the power cable connections 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 or plug 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 steps described in "Testing the computer- to-printer connection" in
the Getting Ready! guide.
The interface cable may not be plugged in securely. Check both ends
of the cable between the printer and the computer. If you are using a
parallel interface, secure the connector using the wire retaining clips.
Make sure that your interface cable meets the specifications for the
printer and computer.
If you are using the serial interface, set the baud rate, protocol, data
bit, and related settings. See your computer manual for the correct
settings and interface requirements.
If you are using the parallel interface, set the SPEED settings to match
the value the computer requires.
Make sure that your software is properly set up for your printer.
The imaging cartridge may be empty. Replace it as described at the
end of this chapter.
