What to do
Check that the power cord is properly plugged into the electrical

If the electrical outlet is controlled by an outside switch or
automatic timer, use a different outlet. Plug another electrical
device, such as a lamp, into the outlet to determine whether the
outlet is operating properly.

Check the printer and the outlet voltage ratings. If the voltages do
not match, unplug the printer immediately and contact your
dealer.
Warning:
Do not reconnect the power cord to an electrical outlet with the
wrong voltage for your printer.
What to do
Turn on the printer.
Turn off the printer and make sure the power cord is firmly
plugged into the electrical outlet and the printer. Then turn on the
power switch.
Use a different outlet.
What to do
Check that the interface cable is not broken or twisted. If you have
another interface cable, replace the cable and check whether the
printer works correctly.
