Thermal Considerations
Electronic components in the EM20-85 will generate heat during the course of their operation. Operating the EM20-85 in
continuous mode for an extended period may cause temperatures to rise on CPU, CIS, LEDs, etc. Overheating can
degrade image quality and affect scanning performance. Given that, the following precautions should be taken into
consideration when integrating the EM20-85.
Avoid continuous use of LEDs for prolonged periods.
Reserve sufficient space for good air circulation in the design.
Avoid wrapping the EM20-85 with thermal insulation materials such as rubber.
Optical Elements
Windows should be designed to prevent the surface of lens from being exposed to contaminants such as dust, liquids, or
grease, which may lead to damage to lens and degrade scanning efficiency.
During installation, keep the surface of lens away from any objects to prevent scratching and contamination of lens. The
operator should avoid talking directly towards lens.
