[. . . ] OverScan Overscan allows you to add a specific margin at top and bottom or right and left (Options vary based on the type of scanner) of the edge of the image. This is used to reduce possible corner clipping on the skewed images and often applied to a batch of skewed document to be scanned in the auto document feeder. Note the overscan result will not be shown in the Display window and that the availability of the function varies based on type of scanner. If enable is selected, you can set the amount of time the scanner starts pre-feeding your paper after your documents has been loaded into the feeder. Transport Timeout Set the amount of time the scanner will wait and then start auto scan after the first scan job is completed. If you have many separate documents need to be scanned at the same scan settings, this feature is especially useful. The value ranges from 0 to 30 seconds. 4-34 User's Manual Note: 1 Within the specified timeout period, if you load your document to the feeder, the scanner starts scanning automatically. 2 If your scanner has a flatbed option and you place your paper on the flatbed, after the timeout period, you need to click the Scan button on the TWAIN user interface to start scanning. 4-35 4. 6 The Multi-Feed Detection Tab Multi-Feed Detection Multi-Feed Detection allows you to detect overlapped document that go through the auto document feeder. Multi-Feed usually occurs due to stapled documents, adhesives on documents, or electro-statically charged document. Note The availability of the function varies based on type of scanner. 4-36 User's Manual Additional Length Detection Additional Length Detection allows you to define the length of document being multi-fed. This value indicates the additional length exceeding your scan area. The Display window will show the size of the document as you change the value. A value of 0 indicates no additional length detection. The Additional Length Detection is best used when scanning samesize documents in the auto document feeder. Intelligent Mode (Skip Multi-Feed) By Ultrasonic Detection Some documents which are glued with a photo or a label may easily be detected as multi-feed yet you wish to bypass these multi-feed conditions. In this case, you can use the intelligent mode to let the scanner memorizes and skips these multi-feed conditions. Choice includes Disable, By Length, By Position, By Length+Position. By Length: When a multi-feed is detected for the first time, the scanner memorizes the length of the paper attached to the document. When you perform next scanning, this pattern of multi-feed will be bypassed. By Position: When a multi-feed is detected for the first time, the scanner memorizes the position of the paper attached to the document. When you perform next scanning, this pattern of multi-feed will be bypassed. 4-37 By Length+Position: When a multi-feed is detected for the first time, the scanner memorizes the length and position of the paper attached to the document. When you perform next scanning, this pattern of multi-feed will be bypassed.
