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.

In the ISIS/TWAIN driver properties dialog box, click the [Others] tab 
→ 
select the [Rapid recovery system] check box 
→ 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.
This section describes the procedure for setting the scanner to stop document 
feeding when double feeding of document pages is detected.

Click the [Others] tab 
→ select the [Detect by Length] or [Detect by 
Ultrasonic] (for the DR-2510C only) check box under [Double Feed 
Detection 
→ click [OK].
NOTE
Details of each detection method are indicated below.
[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 ultrasonic.
