Preventive Maintenance

No preventive maintenance is required other than occasionally vacuuming the printer
mechanism to remove dust and paper debris and regularly cleaning the case exterior with
denatured alcohol. After cleaning the unit, check that it is properly lubricated as described
under Lubrication, below. Also inspect the springs and rollers to see that they are operating
properly.
Disconnect the printer from the external AC power source before performing maintenance
