Solving printing problems
Some printer problems are very easy to solve. If your printer is not responding, first make sure:
•
The printer cable is securely attached to the printer and the host computer.
•
The power cord is plugged into the printer and a properly grounded electrical outlet.
•
The printer is turned on.
•
The electrical outlet is not turned off by any switch or breaker.
•
The printer front, top, and rear doors are completely closed.
•
All printer options are properly installed.
Once you’ve checked each of these possibilities, turn the printer off and back on. This often fixes the
problem.
If a message appears on the operator panel display, see
Understanding printer messages
for more
information. If the message indicates the printer has a paper jam, see
Clearing paper jams
.
If you are having trouble determining the source of the problem, see
Print quality problems
for other
suggestions.
The information in the following tables may help you solve printing problems. If these suggestions do
not correct the problem, call for service. You may have a printer part that requires adjustment or
replacement.
