Calibrating the Multi-
Feed Detector
You need to calibrate the Multi-Feed Detector to set the double
thickness threshold. Calibration should be performed every time a
set of documents with different thicknesses has to be scanned. If you
are not scanning documents of different thicknesses, calibration
should be performed more often (depending on the volume of
documents being scanned), or at least one a week.
The optimum threshold set value is one that is very close to the actual
document thickness that is being imaged. Documents must be very close
to the same thickness in order for the Multi-Feed Detector to function
properly.
To calibrate the thickness threshold follow the steps below:
1. Stop the transport.
2. Disable the Multi-Feed Detector by pressing the lower button so it is
not illuminated.
3.
Press the Calibrate button (it should illuminate).
4. Start the transport by pressing the green Run key.
5. When both Multi-Feed Detector buttons are flashing together, feed a
representative sample of the calibration document so that it passes
under the thickness sensor. This document thickness will be
measured and stored as the new thickness threshold.
When calibration is complete, the buttons will stop flashing and the Multi-
Feed Detector will automatically be enabled (the Multi-Feed Detector
Enable button will be illuminated).
NOTE: The thickness calibration document will be scanned unless the
machine is placed in a non-scanning mode (i.e., Count Only
mode) prior to thickness calibration.
