Detecting a document double feed
This scanner includes a function to detect document double feeds. By
using this function, the scanner will automatically stop when it detects
that multiple documents have been fed at the same time. You can also
specify whether to save the scanned image after scanning has
finished and continue scanning the document (double feed detection
ignore function).
To use the double feed detection function, you must first open the
scanner driver settings screen and enable double feed detection. It is
also necessary to set [Rapid recovery system] to use the double feed
detection ignore function.
Setting procedure

Opens the scanner driver's Detail Settings screen.

Open the [Error Detection] Tab.

Select either the [Detect by Length] or the [Detect by
Ultrasonic] check box (or both).

the [Others] tab and select the [Rapid recovery system]
check box.

IMPORTANT
• If documents like plastic cards are scanned, it may be falsely
detected as a double feed.
• Depending on the paper type and paper thickness, false
detection of double feed may occur. If the double feed
detection malfunctions, clear the [Detect by Ultrasonic] check
box of the [Error detection] tab.
