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.
WARNING:
•
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 dam-
age 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 unit after turning the main power
OFF. Wait several minutes until the thermal fuser unit cools down.
CAUTION:
•
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 in-
correct 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 un-
expected result, or not at all.
•
When replacing batteries, or boards with memory installed, the
memory contents will be cleared. Be sure to print a communica-
tion 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.
