CHAPTER 3 DISASSEMBLY/REASSEMBLY
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 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.
• After disconnecting flat cables, check that each cable is not damaged at its end or
shortcircuited.
• When connecting flat cables, do not insert them at an angle. After insertion, check that the
cables are not at an angle.
• When connecting or disconnecting harnesses, hold the connector body, not the cables. If
the connector is locked, release it first.
• After a repair, check not only the repaired portion but also harness treatment. Also check
that other related portions are functioning properly.
• Forcefully closing the front cover without mounting the toner cartridge and the drum unit
can damage the machine.
• After assembly, it is recommended to conduct dielectric strength test and continuity test.
• When mounting the inlet, check that the inlet is housed in the frame completely and that
the harness is not caught in the frame.
• The insulation sheet should not be damaged.
• After a repair, update the firmware to the latest version.
WARNING
Some parts inside the machine are extremely hot immediately after the machine is used.
When opening the front cover ASSY or back cover to access any parts inside the
machine, never touch the shaded parts shown in the following figures.
WARNING
When removing the Low-voltage power supply, do not touch it
within 3 minutes after disconnecting the AC cord as it may cause
an electric shock due to the electric charge accumulated in the
capacitor.
