10. Maintenance This chapter describes how to maintain the machine. Cleaning Cautions to Take When Cleaning R WARNING: • Do not attempt any maintenance or troubleshooting other than that mentioned in this manual. This machine contains a laser beam generator and direct exposure to laser beams can cause permanent eye damage. R CAUTION: • The inside of this machine becomes very hot. Do not touch parts labelled "v" (indicating a hot surface). • Be sure to disconnect the plug from the wall outlet and clean the prongs and the area around the prongs at least once a year. Allowing dust to build up on the plug constitutes a fire hazard. Clean the machine periodically to maintain high print quality. Dry wipe the exterior with a soft cloth. If dry wiping is not enough, wipe with a soft, damp cloth that is wrung out well. If you still cannot remove the stain or grime, use a neutral detergent, wipe over the area with a well-wrung damp cloth, and then dry wipe the area and allow it to dry. Important ❒ To avoid deformation, discoloration, or cracking, do not use volatile chemi- cals, such as benzine and thinner, or spray insecticide on the machine. ❒ If there is dust or grime inside the machine, wipe with a clean, dry cloth. ❒ You must disconnect the plug from the wall outlet at least once a year.
