: <Symptom>
Details
Light image
<Cause>
If the machine is located in a place where there is a lot of dust, the dust collects inside the lens unit,
and a large amount adheres to the lens surface. As a result of this, the amount of light from the original
illumination lamp increases to result in a light image.
<Factory measure>
To reduce the amount of dust inside the machine, the air filter has been changed. Also, the shape of
the inner cover (left) has been changed to make possible replacing the air filter without the need to
remove the inner cover (left).
