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.
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.
