• Be sure to unplug the copier from the outlet before attempting to service the copier.
• The basic rule is not to operate the copier anytime during disassembly. If it is absolutely
necessary to run the copier with its covers removed, use care not to allow your clothing to
be caught in revolving parts such as the timing belt and gears.
• Before attempting to replace parts and unplug connectors, make sure that the power
cord of the copier has been unplugged from the wall outlet.
• Be sure to use the Interlock Switch Actuating Jig whenever it is necessary to actuate the
Interlock Switch with the covers left open or removed.
• While the product is energized, do not unplug or plug connectors into the circuit boards
or harnesses.
• Never use flammable sprays near the copier.
• A used battery should be disposed of according to the local regulations and never be dis-
carded casually or left unattended at the user’s premises.
• When reassembling parts, make sure that the correct screws (size, type) and toothed
washer are used in the correct places.
• If it becomes necessary to replace the thermal fuse or any other fuse mounted on a
board, be sure to use one of the rating marked on the blown fuse. Always note the rating
marked on the fuse, as the rating and mounting site or number used are subject to
change without notice.
• Never create a closed circuit across connector pins except those specified in the text and
on the printed circuit.
• When creating a closed circuit and measuring a voltage across connector pins specified
in the text, be sure to use the GND wire.
