Rapid System Recovery This section describes the procedure for setting the system recovery method used by the scanner when document feeding stops due to a paper jam or other error during scanning. 1 Click the [Others] tab in the Properties for Canon DR-3010C dialog box → select the [Rapid recovery system] check box → click [OK]. Double Feed Detection This section describes the procedure for setting the scanner to stop document feeding when double feeding of document pages is detected. 1 Click the [Others] tab → select the [Detect by Length] or [Detect by Ultrasonic] check box under according to the set of documents → click [OK]. NOTE If you select [Rapid recovery system] and a paper jam or other error causes document feeding to stop while scanning, scanning stops without sending an error notification to the application program. After you clear the paper jam or resolve the error, you can resume the normal scanning operations. NOTE [Detect by Length] This detection method is effective when scanning documents of the same size. It detects double-feeding when a document is 2.0" (50 mm) longer or 2.0" (50 mm) shorter than the standard length (the length of the first document). Feeding is stopped when a double-feed is detected. [Detect by Ultrasonic] This detection method is effective when scanning documents of different sizes. It uses ultrasonic waves to detect the gap between documents when more than two sheets of paper are fed at the same time. Feeding is stopped when a double-feed is detected. • The two detection methods can be used at the same time. • When the documents overlap by less than 2.0" (50 mm) or are stuck together due to static electricity, double-feeding may not be able to be detected correctly using Detect by Ultrasonic. • The [Detect by Ultrasonic] check box cannot be selected when scanning folded documents. 52 DR-3010C
