Solving basic printer problems
Sometimes printer problems are very easy to solve. When you have a problem, first make sure that:
•
If an error light blinks, see
•
The printer power cord is plugged into the printer and a properly grounded electrical outlet.
•
The printer power switch is on.
•
The electrical outlet is not turned off by any switch or breaker.
•
Other electrical equipment plugged into the outlet is working.
•
All options are properly installed.
•
If you have checked all of the above and still have a problem, turn the printer power off, wait for
about 10 seconds, and then turn the printer power on. This often fixes the problem.
Note: If any of these do not solve your problem, see the other topics listed in
