1. SAFETY PRECAUTIONS
To avoid creating secondary problems by mishandling, follow the warnings and precautions
below during maintenance work.
• Be careful not to lose screws, washers, or other parts removed.
• Be sure to apply grease to the gears and applicable positions specified in this chapter.
• When using soldering irons or other heat-generating tools, take care not to accidentally
damage parts such as wires, PCBs and covers.
• Static electricity charged in your body may damage electronic parts. When transporting
PCBs, be sure to wrap them in conductive sheets.
• When replacing the PCB and all the other related parts, put on a grounding wrist band and
perform the job on a static mat. Also take care not to touch the conductor sections on the
flat cables or on the wire harness.
• When connecting or disconnecting cable connectors, hold the connector body, not the
cables. If the connector has a lock, release the connector lock first to release it.
• After a repair, check not only the repaired portion but also all connectors. Also check that
other related portions are functioning properly before operational checks.
• After disconnecting flat cables, check that each cable is not damaged at its end or short-
circuited.
• When connecting flat cables, do not insert them at an angle. After insertion, check that the
cables are not at an angle.
WARNING
• Always turn off the power switch and unplug the power cord from the power outlet
before accessing any parts inside the machine.
• When opening the front cover or back cover to access any parts inside the machine,
never touch the shaded parts shown in the following figures.
• DO NOT use flammable substances such as alcohol, benzine, thinner or any type
of spray to clean the inside or outside of the machine. Doing this may cause a fire or
electrical shock.
