Sensitivity controls how aggressively the scanner will work to
determine if more than one document is fed into the transport.
Multi-feeds are triggered by detecting air gaps between documents.
This allows multi-feed detection to be used with job sets containing
documents with mixed thicknesses. You may set the Multi-Feed
Detection to high, medium or low sensitivity. If you disable Sensitivity, no
phase or amplitude checking is used.
NOTE: Regardless of the setting, Post-It™ notes will be detected as
multi-fed documents.
• High Sensitivity: this is the most aggressive setting. this is a good
setting to use if all documents are similar in thickness to 20-lb. Bond
paper.
• Medium Sensitivity: this is the default. Use Medium sensitivity if
your application has varying document thickness or labels attached
to the document. Depending on the label material, most documents
with labels should not be detected as a multi-fed document.
• Low Sensitivity: this setting is the least aggressive setting and is
less likely to detect labels, poor quality or wrinkled documents as
multi-fed documents.
When determining the appropriate setting for your workflow, you should
start at the Medium Sensitivity.
Multifeed Stops Scanning if this option is not selected, the scanner
will display and log the condition but continue to operate. If selected, the
scanner will display, log the condition and stop the feeder (the scanner
will remain enabled). When an overlap or multi-feed is detected, the
scanner stops the feeder, clears the transport of all pages and then the
documents can be refed.
End Job if this option is selected, the scanner will display, log the
condition and stop the feeder and transport (the scanner will be
disabled). Scanning can only be resumed when the scanner is
re-enabled from the host.
With all options, the scanner will beep if the alarm tone volume is set
higher than 0.
