Xerox Assigned Patent for System and Method for Controlling Registration in a Continuous Feed Tandem Printer
ALEXANDRIA, Va., Nov. 2012 — Xerox, Norwalk, Conn., has been assigned a patent (8,303,071) developed by Yongsoon Eun, Webster, N.Y., for a "system and method for controlling registration in a continuous feed tandem printer."The abstract of the patent published by the U.S. Patent and Trademark Office states: "A method enables a printing system to register images printed by two printers accurately. The method includes operating at least one marking station in a first printer with reference to a low frequency component and a high frequency of a velocity measurement for a web in the first printer, printing fiducial marks on the web with a marking station in the first printer, detecting the fiducial marks with a fiducial mark sensor in a second printer, generating a velocity measurement for the web as the web moves along a web path in the second printer that corresponds with the detected fiducial marks, and operating at least one marking station in the second printer with reference to a low frequency component and a high frequency component of the velocity measurement of the web moving along a web path in the second printer."
The patent application was filed on May 11, 2010 (12/777,929). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,303,071&OS=8,303,071&RS=8,303,071
