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.
