TROUBLESHOOTING
This chapter helps you identify printer conditions and problems that you can
often correct yourself.
Your printer is a reliable piece of precision machinery, which should not
cause you any trouble, provided it is used and treated sensibly. However, the
few elementary tips below should help you avoid having to make unnecessary
service calls.
Remember that your printer is a highly sophisticated electronic device, which
also contains high voltage inside. For that reason, only carry out those
operations described in this chapter.

here may result in electric shock and/or damage to the printer.
When carrying out any repairs or maintenance, always follow
the instructions carefully.
