Systems and methods for material authentication
View Patent ↗Systems and methods for authentication of materials used in imaging members and assemblies. Authentication of imaging materials ensure that compatible components are being used with the imaging members and assemblies. Embodiments provide a system and method for efficiently detecting whether materials being used in the imaging members and assemblies are compatible and authentic materials authorized for such uses.
1. A method for authenticating an imaging material used in an ink jet printing apparatus, comprising:
tagging a drum maintenance fluid with at least one fluorescent tag, the at least one fluorescent tag being selected from the group consisting of fluoranthene, fluorescent clear blue dye, and mixtures thereof, and the at least one fluorescent tag being present in an amount of about 0.2 g in 5 g of the drum maintenance fluid;
generating an energy source for stimulating an emission of fluorescent light from the fluorescent tagged drum maintenance fluid;
stimulating the emission of fluorescent light from the fluorescent tagged drum maintenance fluid;
measuring the emission of fluorescent light from the fluorescent tagged drum maintenance fluid at a predetermined wavelength;
subjecting the stimulated emission of fluorescent light from the fluorescent tagged drum maintenance fluid to a filter to remove background interference before measuring the emission of fluorescent light from the fluorescent tagged drum maintenance fluid at the predetermined wavelength; and
identifying a test drum maintenance fluid as authentic when the measured emission of fluorescent light from the test drum maintenance fluid meets a predetermined emission of fluorescent light from the fluorescent tagged drum maintenance fluid at the predetermined wavelength after filtering.
2. The method of claim 1 , wherein the drum maintenance fluid is obtained from a location in a transfix system selected from the group consisting of a drum maintenance roller, a metering blade, a drum surface, a transfix roller, and a media passing through the transfix system.
3. The method of claim 1 further including modifying the fluorescent tag with a chemical moiety compatible with the drum maintenance fluid so that the fluorescent tag is soluble in the imaging material.
4. The method of claim 1 , wherein the fluorescent tag further comprises a dye selected from the group consisting of fluorescein, rhodamine, rosaline, uranium europium, uranium-sensitized europium, and mixtures thereof.
5.

8. A system for authenticating an imaging material used in an ink jet printing apparatus, comprising:
at least one fluorescent tag for tagging a drum maintenance fluid, the at least one fluorescent tag being selected from the group consisting of fluoranthene, fluorescent clear blue dye, and mixtures thereof, and the at least one fluorescent tag being present in an amount of about 0.2 g in 5 g of the drum maintenance fluid;
an energy source for stimulating an emission of fluorescent light from the fluorescent tagged drum maintenance fluid;
a filter for removing background interference from the emission of fluorescent light from the fluorescent tagged drum maintenance fluid before measuring the emission of fluorescent light from the fluorescent tagged drum maintenance fluid at the predetermined wavelength; and

9. The system of claim 8 further including a smart chip coupled to the fluorescence detector for requesting replacement of the test drum maintenance fluid when the test drum maintenance fluid is not authentic.
10. The system of claim 8 , wherein the drum maintenance fluid is obtained from a location in a transfix system selected from the group consisting of a drum maintenance roller, a metering blade, a drum surface, a transfix roller, and a media passing through the transfix system.
11. The system of claim 8 , wherein the fluorescent tag is modified with a chemical moiety compatible with the imaging material so that the fluorescent tag is soluble in the drum maintenance fluid.
12. The system of claim 8 , wherein the fluorescent tag further comprises a dye selected from the group consisting of fluorescein, rhodamine, rosaline, uranium europium, uranium-sensitized curopium, and mixtures thereof.
13. The system of claim 8 , wherein the fluorescent tag further comprises an organic compound selected from the group consisting of poly(methylphenyl siloxane), 1,4-Bis(4-methyl-5-phenyloxazol-2-yl) benzene, 1,4-Bis(5-phenyl oxazol-2-yl) benzene, 2,5-diphenyl oxazole, 1,4-Bis(2-methylstyryl) benzene, trans-4,4′-diphenyl stilbebene, 9,10-diphenyl anthracene, and mixtures thereof.
