While the product is operating, never inspect the drive areas
such as the motor, sprockets and gears.
Since the product is heavy in weight (approx. 25 kg,
consumables not included), two or more personnel are required
to transfer the product. On this occasion, make sure to lay
hands on the specified places.
Special care must be taken to maintain safety devices such as
fuse, INTERLOCK S/W, which are provided to prevent the
product from malfunction and accidents, and also carefully
check the parts such as panel, covers, which are directly
operated by the user.
Do not touch the FUSER ASSY immediately after using the
product, or you may burn your hand. Allow the assy to cool
enough to work with it.
Pay attention to the following when turning the product back
on after servicing.
•
Be careful not to get your hands and clothes caught up in the
rotating parts (various rollers and cooling fans) of the
product.
•
Never touch the electrical terminals and high-voltage
components such as the HVPS and LVPS unit.
To avoid dust explosion or ignition, never bring the
consumables close to flame or throw them into fire.

While servicing the laser printer, never open any cover on
which a Warning Label for Laser beam is attached.
Understand hazardous nature of the laser beam, use extreme
caution to avoid injury of yourself and anyone around you.
When you need to work on the hot part or unit (Fuser Assy, for
example), make sure to unplug the product from power outlet

unit cool down sufficiently to avoid burn injury.
This printer produces a laser beam when the following
conditions are all satisfied.
