Printer Does not Turn On
Caution: Plug the three-wire cord (with grounding prong) directly into a grounded AC outlet only. Do
not use a power strip. If necessary, contact a licensed electrician to install a properly grounded outlet.
Probable Causes Solutions
The power cord is not correctly plugged into
the outlet.
Turn off the printer, and plug the power cord securely into
the outlet.
Something is wrong with the outlet connected
to the printer.
Plug another electrical appliance into the outlet and see
whether it operates properly.
Try a different outlet.
The power switch is not correctly turned on. Turn the power switch on the top of the printer off, wait two
minutes, then turn it back on.
Ensure that the main power switch on the rear of the printer
is in the on position.
The printer is connected to an outlet with a
voltage or frequency that does not match the
printer specifications.
Use a power source with the specifications listed in Electrical
Specifications on page 236.
