used. When opening the front cover or rear cover to access any parts inside the
printer, never touch the red colored parts shown in the following figures.

CAUTION:
(1) Be careful not to lose screws, washers, or other parts removed.
(2) Be sure to apply grease to the gears and applicable positions specified in this chapter.
(3) When using soldering irons or other heat-generating tools, take care not to accidentally damage
parts such as wires, PCBs and covers.
(4) Static electricity charged in your body may damage electronic parts. When transporting PCBs, be
sure to wrap them in conductive sheets.
(5) 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.
(6) Be sure to replace self-tapping screws correctly, if removed. Unless otherwise specified, tighten
screws to the following torque values.

(8) When connecting flat cables, do not insert them at an angle. After insertion, check that the cables
are not at an angle.
(9) 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.
