Patent number: 4645195Abstract: A document printer includes sheet-feeding apparatus for sequentially presenting both faces of a print-receiving sheet to a print station. According to a preferred embodiment, such apparatus features, as part of the duplex sheet path, reversible sheet-feeding means operable in first or second active modes for selectively feeding sheets into and out of a chute, located upstream from the feeding means, to reverse the sheet's lead edge/trail edge orientation. Such sheet-feeding means is also operable in a passive mode in which it allows sheets to advance, without substantial interference, downstream therepast to a registration position.Type: GrantFiled: July 3, 1985Date of Patent: February 24, 1987Assignee: Eastman Kodak CompanyInventors: Robert J. Scranton, Charles W. Spehrley, Jr.

Patent number: 4370665Abstract: A paper transport simulates movement of a plurality of documents past the print station of a ink jet printer. The transport includes an arrangement for transporting a continuous paper web past the print station and a tachometer drive roller for contacting the tachometer wheel of the printer system. The transport further includes a document simulator wheel aligned with the photo-optical document detector of the printer system such that the movement of a succession of documents past the print station may be simulated while the printer system prints upon the continuous paper web.Type: GrantFiled: April 27, 1981Date of Patent: January 25, 1983Assignee: The Mead CorporationInventors: Robert J. Scranton, James R. Meckstroth

Patent number: 4347520Abstract: An ink jet printer includes a print head means which generates two parallel rows of jet drop streams. Charge electrodes are mounted on a pair of charge electrode plates which are movable into and out of drop charging positions. A pair of catchers each define a drop catching surface and a drop ingesting slot along the lower edge of the drop catching surface. Each of the catchers is generally pivotally mounted for rotation about an axis parallel to the rows of jet drop streams. The catchers may be pivoted from a drop catching position, in which the drop catching surfaces are substantially parallel, to a full catch position in which drop catching surfaces are inclined to face upward and intercept the jet drop streams. In the full catch position, the drop ingesting slots are positioned closely together. A linkage arrangement is provided for pivoting the catchers from the full catch position to the drop catch position after start up of the print head means.Type: GrantFiled: September 23, 1980Date of Patent: August 31, 1982Assignee: The Mead CorporationInventors: Suresh C. Paranjpe, James W. Davis, Robert J. Scranton, Roger D. Wells

Patent number: 4283731Abstract: An ink jet printing apparatus for printing addresses on documents being transported along an independently operated conveyor. The printing apparatus includes a control console, a printing arm telescopically received within the console, and an ink jet printing head mounted on a carriage which is vertically movable within the printing arm. A tachometer wheel is mounted on the printing carriage for contacting a document being transported past the printing head and generating a tachometer signal in response thereto. A programmed microprocessor generates printing control signals in synchronism with the tachometer signal.Type: GrantFiled: April 22, 1980Date of Patent: August 11, 1981Assignee: The Mead CorporationInventors: Dennis E. Bok, Patrick E. Bridge, Robert W. Coulter, George W. Denlinger, Clifford S. Fernalld, Jr., Charlie H. Hill, Jr., David A. Huliba, James R. Meckstroth, Robert J. Scranton

Patent number: 4237466Abstract: An ink jet printer includes a rotatable support for supporting a sheet of paper. The support defines an interior vacuum chamber and a plurality of vacuum openings in the surface thereof which communicate with the vacuum chamber. A rotary drive rotates the support and a vacuum source is provided for partially evacuating the vacuum chamber. A paper supply adjacent the rotatable support, loads a sheet of paper onto the rotatable support. An ink jet print head is mounted adjacent the rotatable support for printing on a sheet of paper supported thereon. A sheet diverter is positioned adjacent the rotatable support between the ink jet print head and the paper supply for stripping sheets of paper from the rotatable support when the sheets are not firmly supported thereon. A paper sensor is mounted adjacent the rotatable support, intermediate the sheet diverter and the ink jet print head, for inhibiting operation of the ink jet print head when a sheet of paper is diverted by the paper diverter.Type: GrantFiled: May 7, 1979Date of Patent: December 2, 1980Assignee: The Mead CorporationInventor: Robert J.
