4. Safety
To prevent possible accidents during maintenance activities, you must pay attention to the
"Warning" and "Caution" information in this manual.
Performing any dangerous operations, or procedures not included in this manual, should be
avoided.
Occasionally, it may be required to perform some procedures not covered by this manual.
These procedures should be performed carefully, always giving attention to safety.
4.1 Power source
Keep the power supply off during maintenance activities to prevent electric shock, burns and
equipment damage. Keep the power plug disconnected during the maintenance operation.
If it is necessary for the machine power to be switched ON for voltage measurements or
other similar reasons, sufficient care should be given to prevent electric shock, by following
the procedures in this manual.
While the printer is ON, never touch live components.
Power is supplied to the power unit (LVPS ASSY) even while the printer is off.
Never touch its live components.
Do not touch live components unless otherwise specified.

4.2 Drive units
When servicing gears or other drive units, be sure to turn them OFF and disconnect the
power plug from the receptacle. Whenever possible, drive them manually.
Never touch the gears or other moving parts while the printer is running.
4.3 High-temperature units
When servicing high-temperature units (removal, replacement, adjustment, etc.), be sure to
turn them OFF to prevent burns, injuries and an electrical hazard. Remove the power plug
from the receptacle and allow the unit to cool down before servicing.
Fusing units retain their heat after the power is removed. Wait at least 30 minutes
after removing power before servicing.

4.4 Laser beams
• Direct exposure to a laser beam can damage the eyes and cause blindness.
• Never open a cover that has a laser warning label attached.
• Before disassembling and reassembling this laser printer, be sure to turn the
printer power OFF.
• When servicing this laser printer while it is running, be sure to follow the
procedures specified in this manual.
• You should understand and exercise all safety precautions to prevent injuries
when servicing equipment that uses a laser. Carefully follow procedures to
prevent anyone in the area from exposure to the laser beam.
Laser beams have the following characteristics:
• Frequencies are higher than other beams (sun and electric bulbs) and
phases are uniform so that high monochromatic and convergence performance
can be obtained and thin beams of light can reach places at a long distance.
• Due to the high convergence, beams are highly concentrated in density and
temperature, which is dangerous to human body.
Reference: The frequency of the Laser used in this laser printer produces beams that are
invisible.

vi
4.5 Warning/caution labels
Warning labels and caution labels are attached to this laser printer to prevent accidents.
These labels should be clear and easy to read. Check the labels for any damage such as
peeling or stains when servicing the printer.
