Rapid System Recovery; Double Feed Detection - Canon IMAGE FORMULA DR-3010C User Manual

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.
Click the [Others] tab in the Properties for Canon DR-3010C dialog box →
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.

Double Feed Detection

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] check box under <Double Feed Detection> according to the set
of documents → click [OK].
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.
