Laser Beam - Epson EPL-N3000 Service Manual

Laser Beam

This printer incorporates the laser radiation unit (ROS ASSY) of Class IIIb as specified
in IEC60825-1.
Maximum average electric power: 10 mW
Wavelength:
To prevent the laser radiation unit from emitting the laser beam unexpectedly, this
printer is equipped with a switch (INTERLOCK S/W 5V) which physically cuts off the
power to the laser beam output circuit. The interlock switch turns off the printer when
the top cover is opened.
Take great care not to expose your naked eyes to the laser
W A R N I N G
beam; otherwise, you can lose your eyesight.
Never turn on the interlock switch forcibly without turning it
on by normal operation; otherwise, a laser beam can be emitted
unexpectedly during a maintenance operation.
Never disassemble any part or open any cover to which a
warning label about laser beam is affixed.
If you disassemble or assemble the printer, turn off the power.
If you need to work on the printer with power applied, strictly
follow the instructions in this manual.
Understand how the laser beam functions and take maximum
precautions not to injure yourself or anyone around you.
The laser beam has a narrower frequency band and more
C H E C K
coherent phases than any other light (sunlight, electric light).
P O I N T
The beam has excellent monochromaticity and convergence,
thus it reaches long distances. Because of these characteristics,
the laser beam converges into one point, causing high density
and high temperature. Therefore, a laser beam is harmful to
the human body.
The laser beam in this printer is invisible.
