Detection Functions ● Auto Color Detection Automatically detects whether scanned documents are color, grayscale, or black and white. ● Paper Size Detection Detects the document page size before scanning. Fixed-size scan Auto-size-detection scan ● Skew Detection The scanner stops feeding when a skewed document is detected as it touches the edges of the feeder inlet. ● Staple Detection The scanner stops feeding when it detects the presence of stapled documents. "Staple Detection" (See p. 67) ● Dust Detection Detects dust in the scanning unit and performs error processing as needed. "Dust Detection" (See p. 68) ● 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. "Double Feed" (See p. 66) * A non-detection area can be specified to avoid double-feed detection in areas such as those containing adhesive labels. ● Double feed detection by length The scanner stops feeding when a double feed is detected by comparing document page lengths. "Double Feed" (See p. 66) * Based on the length of the first document page, the scanner detects a double feed when fed a different-length page. ● Prescan At the start of scanning, this function prescans the first page and pauses so that you can adjust brightness and contrast before resuming scanning. ● Verify Scan While scanning, the scanned page count is verified against a prespecified count or that obtained from Count-Only Mode. "Verify Scan" (See p. 56) ● 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. Orientation of document Image rotated by text orientation detection 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. 24
