Uses the ultrasonic sensors inside the scanner to monitor the documents during
feeding, and detects overlapped documents according to the deviation of the
reflected ultrasonic waves.
This is the factory default setting.
- Length
Monitors the document length during feeding, and detects overlapped documents
according to the deviation of detected lengths.
ATTENTION
Do not scan a batch of documents with differing lengths. Doing so causes the false
detection of overlapped documents.
However, if the documents differ in length by 10 mm or less, any document
overlapping will not be detected.
● To scan documents with different lengths, select [Overlapping].
● Even when scanning documents of the same length, if a piece of paper such as a
sticky note, receipt, or photo is attached to a document, the scanner may detect
document overlapping due to the attached paper when [Overlapping] is selected.
In this case, selecting [Length] prevents the false detection of document
overlapping.
- Overlapping and Length
Detects overlapped documents by the combination of [Overlapping] and [Length].
Batch
