Detection Functions ● Auto Image Type Detection The scanner automatically detects whether documents are in black and white or color. ● Auto Paper Size Detection The document page size is detected before scanning. ● Verify Scan While scanning, the count of document pages scanned is verified against a pre-specified count or the count 1 obtained from Count-Only Mode. ● Text Orientation Detection The text orientation on each page is detected, and the scanned image is rotated in 90-degree increments as necessary for normalization. Before You Start Using the Scanner Fixed-Size Scanning Auto-Size Detection Scanning ● Skew Detection The scanner stops feeding when a skewed document is detected as it touches the edge of the feeder inlet. ● Staple Detection The scanner stops feeding when it detects the presence of stapled documents. ● Ultrasonic Double-Feed Detection The scanner stops feeding when the ultrasonic sensor detects that two or more document pages are feeding at the same time. * A non-detection zone can be specified to avoid doublefeed detection in areas such as those containing adhesive labels. ● Double-Feed Detection by Document Length The scanner stops feeding when a double feed is detected by comparing document lengths. * Using the length of the first document page as a reference, the scanner detects a double feed when a page of a different length is fed. ● Prescan At the start of scanning, this function prescans the first page of a document and pauses so that you can use the first image to adjust the brightness and contrast before resuming scanning. Feeding Direction The text orientation is detected and the image is rotated Image Processing ● Prevent Bleed Through/Remove Background Prevents the background or original image on the reverse side of thin originals from appearing in scanned images. ● Image Rotation The scanner can rotate scanned images in 90° increments, or detect the text orientation and rotate the image in 90° increments to correct its orientation. ● Deskew The scanner straightens an image when it recognizes from the image that the document page was fed askew.
