4.Select the detection conditions from [Multifeed Detection] under [ADF Option].

You can choose the following:

None

Multifeed detection is not performed.

Check overlapping

The scanner monitors for the overlapping of documents. The scanner detects a

 

multifeed by differences in ultrasonic propagation. When this method is

 

slected, two more options are available specified by other sections.

 

• Multifeed detection areas can be narrowed separately for left/middle/right

 

Ultrasonic sensors to avoid unintensional multifeed detection of sticked pho-

 

togragh or something on the document. To specify this, go to Step 4 in Sec-

 

tion “8.4 Multifeed Detection” on page 190.

 

• If photogragh or something is sticked on the document and its size and/or

 

position are same, you can easily let the scanner memorize its size and/or

 

position just scanning those document. To use this function, go to Section

 

“8.10 Intelligent Multifeed Function” on page 202 or Section “3.12 Not

Check length

detecting Multifeed for fixed format” on page 95.

The scanner monitors the length of documents. It detects a multifeed by differ-

 

ences in the document length when two or more document sheets are fed over-

Check overlapping

lapping.

The scanner monitors both document overlapping and length to detect

and length

multifeeds.

Hardware settings

The scanner will detect multifeeds according the settings configured on the

 

Software Operator Panel. Refer to “8.4 Multifeed Detection” on page 190.

Furthermore, refer to "7.5 Multifeed Detection Conditions" on page 164 for detailed information about the document for multifeed detection.

5.Click the [OK] button.

The display returns to the [TWAIN Driver] dialog box. Then, perform the scanning operation on the dialog box.

The scanner will stop scanning if a multifeed is detected. When this happens, press the [Send to] button on the Operator panel to eject the multifeed document.
