F72 Skew/Double Detection On/Off — allows you to use a function code
to enable and disable the system. The lights do not change.
When a multi-feed is detected, both buttons illuminate. Depending upon the
scanner or scanner/microimager firmware and how the unit is configured,
one of the following messages will be displayed:
•
• •
•
MCP Version 8.40 or greater displays the following message:
E204
Skewed/Double document - refeed
E107
Warning Skewed/Double document - refeed
•
• •
•
Versions less than 8.40 displays the following message:
E204
Skewed document - refeed
E107
Warning Skewed/Double document - refeed
The Multi-Feed Detector Enable/Disable button indicates the state of the
accessory. If the lamp is ON, the accessory is enabled. While the transport
is stopped, press the lower button to enable or disable the accessory as
desired. The Multi-Feed Detector automatically enables after power-up or a
successful calibration as described in the next section.
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 have to be scanned.
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 greenRun 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 and/or
microfilmed unless the machine is placed in a non-filming or
scanning mode (i.e., Count Only mode) prior to thickness
calibration.
