System and method for metallic object detection in a media transport system
A system and method of detecting the presence of metallic objects in media to be conveyed in a medium transport system is disclosed. One or more metal detectors are included in the medium transport system to detect the presence of metal in the medium being transported. Signals from the metal detectors are sent to a system processor, which analyzes the signals, and produces proximity, duration, and/or intensity values therefrom. One or more microphones may also be included which detect the sound created as the medium is being transported. The processor computes sound values from the microphone signals, and analyzes the computed sound values along with the proximity, duration, and/or intensity values in order determine if the conveyance of the medium along the transport path should be stopped due to the presence of metal in the media or a jam occurring within the medium transport path.
1. A media transport system for detecting metallic codes in media to be input into the media transport system and configuring the system based on the metallic codes, comprising:
an input tray configured to hold media to be fed into the media transport system, at least some of the media including metallic codes embodying encoded information or instructions;
one or more rollers configured to convey the media from the input tray and along a medium transport path;
one or more induction sensors positioned near an entry point of media from the input tray into the medium transport path, wherein the one or more induction sensors are configured to detect the metallic codes and output metallic detection signals representative of the metallic codes;
a processing unit in communication with the at least one induction sensor, the processing unit configured to:
receive the metallic detection signals;
decode the information or instructions; and
issue a command to configure and actuate the media transport system based on the decoded information or instructions and in accordance with predefined configurations.
2. The system of claim 1 , wherein the metallic codes are metallic barcodes or patch codes.
3. The system of claim 1 , wherein the input tray is configured to receive a folded document containing at least one metallic code, and wherein the processing unit is configured to decode commands from the at least one metallic code to configure the media transport system to image and electronically unfold the document.
4. The system of claim 1 , wherein at least of some of the media are checks, are wherein the metallic codes are included in metallic foil or metallic ink on the checks.
5. The system of claim 4 , wherein the processing unit is configured to configure an image controller in the media transport system to identify checks for special processing.
6. The system of claim 5 , wherein the special processing includes extracting check information from the metallic foil or metallic ink.
7. The system of claim 1 , wherein the one or more rollers include a feed roller, and wherein at least one or of the one or more induction sensors is positioned near the feed roller in the media transport system.
8. The system of claim 1 , wherein at least one or of the one or more induction sensors are located in the input tray.
9. The system of claim 1 , wherein the at least one induction sensor includes a plurality of induction sensors.
10. A method for configuring a media transport system based on metallic codes in media to be input into the media transport system, comprising:
inputting media to be fed into the media transport system into an input tray, at least some of the media including metallic codes embodying encoded information or instructions;
conveying the media from the input tray and along a medium transport path with one or more rollers;
detecting the metallic codes with one or more induction sensors positioned near an entry point of media from the input tray into the medium transport path;
outputting, from the induction sensors, metallic detection signals representative of the metallic codes;
receiving the metallic detection signals at a processing unit;
decoding, by the processing unit, the information or instructions; and
issuing a command, from the processing unit, to configure and actuate the media transport system based on the decoded information or instructions and in accordance with predefined configurations.
11. The method of claim 10 , wherein the metallic codes are metallic barcodes or patch codes.
12. The method of claim 10 , wherein inputting media includes inputting a folded document containing at least one metallic code indicating it is a folded document, the method further comprising configuring the media transport system to image and electronically unfold the document.
13. The method of claim 10 , wherein at least of some of the media are checks, are wherein the metallic codes are included in metallic foil or metallic ink on the checks.
14. The method of claim 13 , further comprising configuring an image controller in the media transport system to identify checks for special processing.
15. The method of claim 14 , wherein the special processing includes extracting check information from the metallic foil or metallic ink.
16. The method of claim 10 , wherein the one or more rollers include a feed roller, and wherein at least one or of the one or more induction sensors is positioned near the feed roller in the media transport system.
17. The method of claim 10 , wherein at least one or of the one or more induction sensors are located in the input tray.
18. The method of claim 10 , wherein the at least one induction sensor includes a plurality of induction sensors.
