Safety Precautions
(9) When connecting or disconnecting cable connectors, hold the connector bodies not the
cables. If the connector has a lock, always slide the connector lock to unlock it.
(10) After repairs, check not only the repaired portion but also that the connectors and other
related portions function properly before operation checks.
Notes
• On the next page is a disassembly order flow which helps you access the object
component.
• Unless otherwise specified, the disassembled parts or components should be
reassembled in the reverse order of removal.
To prevent the creation of secondary problems by mishandling, observe the following precau-
tions during maintenance work.
(1) Always turn off the power before replacing parts or units. When having access to the power
supply, be sure to unplug the power cord form the power outlet.
(2) Be careful not to lose screws, washers, or other parts removed for parts replacement.
(3) Be sure to apply grease to the teeth of gears.
(4) When using soldering irons and other heat-generating tools, take care not to damage the
resin parts such as wires, PCBs, and covers.
(5) Before handling the PCBs, touch a metal portion of the equipment to discharge static
electricity, or the electronic parts may be damaged due to the electricity charged in your
body.
(6) When transporting PCBs, be sure to wrap them in conductive sheets such as aluminum
foil.
(7) Be sure to reinsert self-tapping screws correctly, if removed.
(8) Unless otherwise specified, tighten screws to the torque values listed below.
