Double Feed Detection
The scanner is equipped with an infrared double feed detection sensor that
automatically detects when two or more documents are fed at the same time
(double feed) while scanning continuously. When the scanner detects a double
feed, it stops scanning.
IMPORTANT
• The following types of document may be misdetected as double fed:
• Documents with a colored background
• Documents with a glossy finish
If misdetection of double feeds occurs often, turn off double feed detection.
• Double feed detection is valid for documents with a thickness within the
range 0.004” to 0.005” (0.10 mm to 0.14 mm). Double feeds cannot be
detected for thicker or thinner documents.
