Chapter 4 Other Functions
IMPORTANT
•Ultrasonic
•If documents stick together due to static electricity, Ultrasonic
•If the presence of adhesive notes or labels on pages is detected as a double feed and you do not want to remove them for scanning, a
When a double feed is detected with Ultrasonic double- feed detection, this function transports the double fed pages back to the feeder inlet and tries scanning again. You can set this function from the User Mode. (See “Double- Feed Retry Setting” on p.
If a long document page becomes skewed as it is fed, the page may press against the edge of the feed inlet or transport path and be damaged.
When the scanner detects that a skewed page is contacting the edge of the transport path, an error message is displayed and transport stops.
IMPORTANT
•A page that becomes skewed while it is fed is only detected by the sensors as skewed if it contacts the edge of the transport path during scanning.
•Note that the ISIS/TWAIN driver has a Deskew function that can detect a skewed document from the scanned image, and straighten it.
When sensors at both sides of the feed inlet detect the bent corner of a stapled document, an error message appears and feeding stops.
IMPORTANT
•Staple detection detects the bent corner that occurs when one of the four corners of a document has been stapled.
•Staple detection may not operate properly in the following cases where bending does not occur in documents.
–The document is stapled at two or more corners.
–The document is size smaller than STMT/A5.
–The position of the left or right document guide has been changed, and the document has been shifted to the left or right side. (See “Adjusting the Document Guides” on p.
•Be careful to keep the staple detection window glass clean, and wipe the glass if dust is present.
Hint
•Staple detection is controlled in the ISIS/TWAIN driver, and the detection level can be set in the User Mode. (See “Staple Detection Level Setting” on p.
•Staple detection for the
