8.2 Structure
(1) Laser Unit
The laser unit comprises a laser diode, finite lens and aperture.
Laser diode
The laser diode is compact, efficient, low-price, operates on lower power, and has a long life.
However, it is sensitive to heat.
Laser diode controls emission of laser beams based on the laser control (ON/OFF) signals from
the laser drive board.
LASER SAFETY
The beam of the semiconductor laser is itself extremely weak (about 5 mW), but focusing the
parallel rays results in an increase in energy to which extended exposure is hazardous.
The laser optical system of the digital plain paper copier is encased in metal which in turn is
housed in the external cover. There is thus no risk of leaks during use, nor during normal servic-
ing.
Note, however, that the laser beam is not visible, and extreme care must be exercised when
servicing involves focusing the laser. Such operations are hazardous and must not be attempted
unless you are specifically trained to work in this area.
The warning label shown below is attached on the PU guide assembly.
Fig. 8-2-1
[CAUTION]
• Do not insert tools that are highly reflective into the path of the laser beam.
• Remove all watches, rings, bracelets, etc.
