Cleaning the Image Sensor
Occasionally, it might be necessary to clean the image sensor.
1. Remove the front cover and the endorsement printer cover.
2. Open both the front and back panels that cover the image sensor.
The front panel can open up to 90°. The back panel opens only a
few degrees.
3. Use any of the following to gently remove any ink or dust from
the image sensor.
• A lens cleaning tissue.
• A damp lint-free cloth.
• A cotton swab dampened with rubbing alcohol to gently
clean the image sensor.
4. Clean the glass on each panel thoroughly.
5. Replace each of the covers.
Caution:
• Always disconnect the unit from its power source before cleaning the image sensor.
• Do not use a cleaning card to clean the imager as it will scratch the image sensor.
