as a brief guide. Remember that your printer is a highly sophisticated

electronic device, which also contains high voltage inside. For that reason,

CAUTION: Any attempt to carry out operations other than those described

here may result in electric shock and/or damage to the printer.

When carrying out any repairs or maintenance, always follow

the instructions carefully.

ideas on where to look in this section if you experience problems:

Remember - it is better not to attempt operations or repairs above your level
