Ultrasonic Detection 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.
• 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.
• 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.
• 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.
When determining the appropriate setting for your workflow, you should
start at Medium sensitivity.
Units defines the primary measurement system. Pixels, Inches and
Centimeters are available.
Energy Saving Features of Scanner allows you to set the amount
of time the scanner will remain inactive before the scanner goes into an
idle state (sleep mode). Choices are: 5 to 60 minutes. The default is 15
minutes.
Transport Timeout allows you to set a transport timeout value. This
value is the amount of time the scanner will wait after the last document
enters the transport before the transport timeout action is taken. You can
specify a time delay setting from 3 to 30 seconds. The default is 8
seconds.
