General Troubleshooting
This section contains procedures to help you locate and resolve problems. Some problems can be
resolved by simply restarting the printer.
To restart the printer:
1. Locate the ON/OFF switch on the front of the printer below the control panel.
2. Turn the switch OFF, wait 20 seconds, and turn the switch back ON.
If the problem is not resolved by restarting the printer, see the table in this chapter that best describes
the problem.
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, then 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 off, wait two minutes, then
turn it back on.
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 243.
