Using Infrared Double Feed Detection The double feed detection function that the scanner is equipped with uses the infrared sensor to detect when two or more documents are fed at the same time. If false detections happen too often, disable the double feed detection function. 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 0.10 mm to 0.14 mm (0.004" to 0.006"). Double feeds cannot be detected for thicker or thinner documents. 34
