Multi-Feed Detector For use with the: Document Scanner 9500 Document Scanner/Microimager 990 Kodak Imagelink Scanners 900 and 923 Kodak Imagelink Microimager 70 User’s Guide A-61120 Part No.
Using the Multi-Feed Detector Introduction The Kodak Digital Science Multi-Feed Detector aids in document processing by detecting documents that may go through the feeder one on top of the other. Multi-feeds can easily happen due to damp documents, adhesives on documents, electrostatically charged documents, or a maladjusted feeder gap.
• Enabling/disabling the Multi-Feed Detector Labels should be placed on the documents so they do not pass under the thickness sensor. If the labels on the document will pass under the thickness sensor, they must be less than or equal to ½-inch in length and spaced greater than 1 inch. They must be placed 2 inches or more from the trail and lead edges of a document. The Multi-Feed Detector is controlled by two buttons located to the left of the document output tray as you are facing the machine.
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.
Operating the scanner with the Multi-Feed Detector enabled When the Multi-Feed Detector is enabled, the scanner is continuously checking documents for multi-feeds when the transport is running. When a multi-fed document is encountered, an error will be reported. The scanner will report a document as a true multi-fed document if it overlaps another document by ¾ of an inch or more.
Retracting the thickness sensor Under normal circumstances, you should not need to adjust the thickness sensor manually. However, if you are feeding documents of mixed thickness or lightweight documents, you may need to manually retract the thickness sensor. To do this: 1. Open the front cover of the scanner. 2. Release the feeder latch and lift the top of the feeder upward. 3. Press the extended portion of the sensor in until it snaps up into the retracted position.
5. Close the front cover. 6. If desired, calibrate and re-enable the Multi-Feed Detector. See the section entitled, “Calibrating the Multi-Feed Detector” for more information. Error recovery Error recovery methods are required when a multi-feed has been detected. The two methods described below meet the needs of most users. However, other methods may be used.
Batch/offline method Use the Batch/Offline method when your primary concern is efficient use of time, duplicates in the database do not represent a problem, and there is adequate space in the scanned image database or film roll for the duplicate images (same images with different sequential ID numbers and image addresses.) Follow these steps to use the Batch/Offline method: 1. Remove the stack of successfully scanned documents from the exit hopper. 2.
Both Multi-Feed Detector buttons are not constantly illuminated: Condition 8 Cause Skewed document, not a multi-feed Encountered a skewed document. Calibration — both lights continue to flash Document feed missed the sensor during calibration. • • Press the green Run button to continue. Refeed the document so it passes under the sensor to complete the calibration.
