Detection | Description |
|
|
None | Does not detect multifeeds. |
|
|
Check | Detects multifeed by the overlapping of |
Overlapping | documents. |
(Ultrasonic) | When this is selected, you can also specify the |
| two following options: |
| z Specify the detection range by the length |
| from the leading edge of the document. |
| Proceed to "Specifying the Area to Detect |
| |
| |
| 210) for more details. |
| z Ignore the multifeed when there is paper of |
| the same size attached to a designated |
| location on the page. |
| Proceed to "Bypassing Multifeed Detection |
| for a Fixed Format" (page 114) for more |
| details. |
|
|
Check Length | Detects multifeed by the difference in length of |
| the documents. |
| Note that multifeed cannot be detected |
| accurately when scanning a mixed batch (in |
| different sizes) or a Job Separation Sheet. |
|
|
Check | Detects multifeed by a combination of [Check |
Overlapping and | Overlapping (Ultrasonic)] and [Check Length]. |
Length | Note that multifeed cannot be detected |
| accurately when scanning a mixed batch (in |
| different sizes) or a Job Separation Sheet. |
|
|
Length | Select a length difference from 10/15/20 mm. |
| Any length under the specified length will not |
| be detected as multifeed. |
|
|
zTo scan documents with different lengths, specify [Check Overlapping (Ultrasonic)].
zWhen a photo or a piece of paper is attached on the document, the overlapping part of the document may be falsely detected as multifeed if [Check Overlapping (Ultrasonic)] is specified. In this case, specify [Check Length].
Note however that [Check Overlapping (Ultrasonic)] can still be used by restricting the detection range.
This setting can also be configured in the scanner driver’s setup dialog box. Note that priority is given to the scanner driver setting.
