Troubleshooting
Solving basic printer problems
If there are basic printer problems, or the printer is unresponsive, make sure:
The power cord is plugged into the printer and a properly grounded electrical outlet.
The electrical outlet is not turned off by any switch or breaker.
The printer is not plugged into any surge protectors, uninterrupted power supplies, or extension cords.
Other electronic equipment plugged into the outlet is working.
The printer is turned on. Check the printer power switch.
The printer cable is securely attached to the printer and the host computer, print server, option, or other network
device.
All options are properly installed.
The printer driver settings are correct.
Once you have checked each of these possibilities, turn the printer off, wait for about 10 seconds, and then turn the
printer back on. This often fixes the problem.
