Black Dots on Image
Black Dots on Image Artifact Example
Cause
Black dots on image. These dots (streaks) are caused by an Electrostatic Discharge (ESD). These ESD dots
generate very short sharp and high light sparks that are coupled into the Photo multiplier through the blue filter. The
ESD effect is induced by several factors, mainly environmental conditions such as dry air and low humidity, and
rubbing of the screen by the mechanical CR Reader (rollers).
Fix
Clean the screen with screen solution that contains anti-static agent. See the User Guide and/or Service Manual for
cleaning instructions.
