Detect stapled documents
Select this option to have the scanner warn you if a stapled page has been detected. When the scanner detects
the stapled page it will stop scanning so that you can fix the problem and start the scan again.
Skew detection
This option detects when a page has been fed through at an angle. Select an option from the drop menu to turn
on this feature. When scanning, always make sure the paper guides have been properly adjusted to the width of
the documents in the input tray. This helps to prevent the pages from being pulled through at an angle.
Document Handling
Select the type of paper in your scan batch. Leave the default selection for Normal paper handling to have the
scanner feed items at normal scan speeds. Select Delicate to have the scanner slow the feeding motor so that
very thin or fragile paper does not tear as it is fed through the scanner.
Patch Code Action
Select an option from this list to enable detection of patch code sheets while scanning.
• Detect and include —the scanner will detect the sheet and then retain an image of the sheet in the output
scan.
• Detect and exclude —the scanner will detect the sheet and then discard the image of the sheet so that it is
not included in the output scan.
The action that occurs when a patch code is detected is dependent on the scanning application you are using.
Patch code detection is an advanced feature and should only be used if you are already familiar with the
technology.
Use the Search direction options to specify the orientation of the patch code sheet relative to the feed direction.
The scanner detects these sheets in the document stack as follows:
• The scanner will only detect sheet data that faces the Simplex lamp module.
Patch code sheets are available on the scanner’s installation disc for you to print and use. The scanner can detect
patch codes 2, 3 and T. The file is located in the user guides section for the scanner on the installation disc. Print
the sheets that are appropriate for the size of the pages being scanned. For instance, if you are scanning A4
pages, print the sheet that is in the bookmark for A4.
Threshold
Adjust the midpoint gray level for deciding what is black and what is white on a patch code sheet.
Lower this value if your patch code appears on a darker background. Raise this value if your patch code appears
on a lighter background.
