6.1 PREVENTIVE MAINTENANCE
Although this printer is designed so that no specific maintenance is required on a regular basis, it is
recommended that you clean the printer thoroughly whenever you get a chance to do so. You can
clean:
Outer case
Use a soft, clean cloth, dampened with mild detergent, if necessary.
Auto sheet feeder
If the inside of the auto sheet feeder is dirty (dusty), carefully brush away all dust and dirt
using a soft brush. If the pickup roller of the sheet feeder is dirty, clean its surface with a soft,
clean cloth.
Inside the printer
If you notice any dust or dirt that has accumulated inside the printer when you open the outer
case for repair, remove all dust and dirt using a small vacuum cleaner designed for such
purposes.

trichloroethylene,
or ketone-based solvents for cleaning. These
chemicals can damage the components of the printer.
