Detection Method | Description |
|
|
Check Overlapping | Detects multifeeds by checking for |
(Ultrasonic) | document overlapping. |
| When this option is selected, the following |
| two more detection options can be set: |
| • You can specify the multifeed detection |
| range by the length from the leading |
| edge of document. Go to "Specifying the |
| |
| |
| |
| • If two or more sheets of paper of the |
| same size are stuck on the same |
| position of the document, you can |
| cancel the Multifeed Detection for that |
| area. Go to "Bypassing Multifeed Detec- |
| |
|
|
Check Length | Detects multifeeds by monitoring the differ- |
| ence of the document length. |
|
|
Check Overlapping | Detects multifeeds when both [Check |
and Length | Overlapping(Ultrasonic)] and [Check |
| Length] are selected. |
|
|
Length | Select 10, 15, or 20 mm as the document |
| length difference, which is to be considered |
| as a Multifeed, when [Check Length] is |
| selected. If the detected document length |
| does not reach the selected length, it will be |
| recognized just as an error, and thus will not |
| be recognized as a multifeed. |
|
|
•When scanning documents of different lengths
！together in the same stack, select [Checking Overlap- ping(Ultrasonic)].
•If something like a stamp, memo or photo is glued to the document, specifying [Checking Overlap- ping(Ultrasonic)] may wrongly detect the glued section as an overlap error. When scanning such a document, select [Checking Length] instead. Note you can also select [Checking Overlapping(Ultrasonic)] by limiting the detection range.
You can also use the scanner driver to configure the settings above. In this case, the settings in the scanner driver are given a priority.
