Other Precautions
!! 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. Otherwise, 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. Made 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 locking mechanism.
!! If the product is to be run with the front door open, make sure that the toner hopper is in the
locked position.
