Safety
Prevention of Physical Injury
1.
Before disassembling or assembling parts of the machine and peripherals, make sure that the
machine and peripheral power cords are unplugged.
2.
The plug should be near the machine and easily accessible.
3.
Note that some components of the machine and the paper tray unit are supplied with electrical
voltage even if the main power switch is turned off.
4.
Always unplug the power cord from the power source before you move the product. Before you
move the machine, arrange the power cord so it will not fall under the machine.
5.
Disconnect all peripheral units (finisher, LCT, etc.) from the mainframe before you move the
machine.
6.
If any adjustment or operation check has to be made with exterior covers off or open while the main
switch is turned on, keep hands away from electrified or mechanically driven components.
7.
The machine drives some of its components when it completes the warm-up period. Be careful to
keep hands away from the mechanical and electrical components as the machine starts operation.
8.
The inside and the metal parts of the fusing unit become extremely hot while the machine is
operating. Be careful to avoid touching those components with your bare hands.
9.
To prevent a fire or explosion, keep the machine away from flammable liquids, gases, and
aerosols.
10.
Do not use flammable sprays or solvent in the vicinity of the machine. Also, avoid placing these
items in the vicinity of the machine. Doing so could result in fire or electric shock.
11.
To avoid fire or explosion, never use an organic cleaner near any part that generates heat.
12.
Clean the floor completely after accidental spillage of silicone oil or other materials to prevent
slippery surfaces that could cause accidents leading to hand or leg injuries.
13.
Never remove any safety device unless it requires replacement. Always replace safety devices
immediately.
14.
Never do any procedure that defeats the function of any safety device.
15.
Modification or removal of a safety device (fuse, switch, etc.) could lead to a fire and personal
injury. Always test the operation of the machine to ensure that it is operating normally and safely
after removal and replacement of any safety device.
16.
For replacements use only the correct fuses or circuit breakers rated for use with the machine.
Using replacement devices not designed for use with the machine could lead to a fire and personal
injuries.
17.
For machines installed with the ADF/ARDF:
When a thick book or three-dimensional original is placed on the exposure glass and the ARDF
cover is lowered, the back side of the ARDF rises up to accommodate the original. Therefore, when
closing the ARDF, please be sure to keep your hands away from the hinges at the back of the
ARDF.
18.
When using a vacuum cleaner around the machine, keep others away from the cleaner, especially
