3.5.1 Remarks before Starting Work
Before starting work, read and understand the following. Otherwise, accidents may occur that can result
in injury to you or damage to the machine. The contents of this chapter should be noted along with the
notes or remarks described in the operator's manual.
Remarks:
• This machine has a high-voltage power supply unit. Turn the power switch OFF and unplug
the power cord before starting any kind of work.
• Do not work with wet hands or wet clothes. Do not wear loose clothing that can become
entangled in the gears, rollers, etc.
• Be certain to plug and unplug cables and wires while holding the connector. Plugging or
unplugging by holding the harness can damage the wires in the cable or cause electrical
shock.
• Do not touch the PC boards directly. Static electricity discharge may damage the components.
Be sure you are properly grounded before working.
• Do not touch the thermal fuser after turning the main power OFF.
Wait several minutes until the thermal fuser unit cools down.
Notes:
• Always work on a suitable table or bench. The working area must be well ventilated.
• Always be sure to use the correct screws and fasteners. If an incorrect screw or fastener is
used it may result in binding, or cause some other obstruction, with a nearby part. Also be
careful not to lose screws.
• Take care that cables and connectors are properly fitted together.
Also be sure that connectors of a similar size and shape are not connected to the wrong
place. The machine may operate with unexpected result, or not at all.
• When replacing batteries, or boards with memory installed, the memory contents will be
cleared. Be sure to print a communication journal, function list, and the telephone lists before
starting.
Turn the power switch OFF after confirming that the residual memory in the LCD window
shows 100% or the image (PIX) memory will be cleared and it cannot be recovered.
• Be careful when handling the drum unit. Do not touch the drum surface. Keep it horizontal. Do
not leave it exposed to light for a long time, etc.
• When using a magnetic tool, do not let it touch the boards having memory chips, controllers,
etc. It will cause malfunctions or memory defects.
• Be very careful when handling the LSU. (Do not drop or handle it roughly, do not disassemble,
etc.)
• Be sure to remove attachments and accessories (as required) such as the recording paper
exit tray, document exit tray, etc.
