• To reassemble the product, reverse the order of disassembly unless otherwise specified.
• While the product is energized, do not unplug or plug connectors into the circuit boards or harnesses.
• The magnet roller generates a strong magnetic field. 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. Other-
wise, use a blower brush and cloth when cleaning parts.
• When handling circuit boards with MOS ICs, observe the "INSTRUCTIONS FOR HANDLING THE PWBs
WITH MOS ICs" (applicable only to the products using MOS ICs).
• The PC Drum is a very delicate component. 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. Make sure that all parts, wiring and screws are returned
to their original positions.
• Check the area surrounding the service site for any signs of damage, wear, or need of repair.
• Do not pull out the toner hopper while the toner bottle is turning. This could result in a damaged hopper motor or
