Do not bring it near a watch, floppy disk, magnetic card, or CRT tube. · An air gun and vacuum cleaner generates a strong electrostatic charge that can destroy the ATDC sensor and other sensors. Before cleaning a component with one of these devices, be sure to remove all the sensors.

Observe the precautions given in "HANDLING OF THE PC DRUM" because mishandling may result in serious image problems. · Note that replacement of a circuit board may call for readjustments or resetting of particular items, or software installation. · After completing a service job, perform a safety check.
