Patent number: 6042100Abstract: A pinch roller acts in combination with a drive roller to provide a nip through which sheets are passed in a sheet handling system. To reduce hand-off errors in the line feed accuracy of the sheet handling system, the pinch roller includes a compliant outer surface and soft undersurface volume. The flexibility of the outer surface allows the pinch roller to shift its holding force from the media to the pinch roller as the media leaves the nip between the rollers. This reduces the force seen by the media in the direction of the media travel, thus reducing the localized push on the back edge of the media. The soft undersurface volume is formed by a foam core.Type: GrantFiled: March 3, 1998Date of Patent: March 28, 2000Assignee: Hewlett-Packard CompanyInventors: Jeffrey E. Jones, Glenn Gaarder, Samuel A. Stodder

Patent number: 5651623Abstract: A multiple-function printing device provides for picking pages from a stack of sheets in an input feeder for roller-driven movement along a first path through a printing station to an output, and for picking pages from a stack of documents in an input feeder for roller-driven movement along a second path through a scanning station to an output, with at least a portion of the first and second paths being commonly shared, and with common mechanisms being used for various steps such as for picking, providing roller-driven movement through the processing stations, and for actuating a pressure plate in the input feeders. A document guide in a document scanning mode of operation is pivoted into a lowered position generally parallel to the print station platen to constrain and contain the top and bottom of any curled document exiting from the scan station into an output roller nip so as to prevent an incipient paper jam. Prior to a printing mode of operation on a paper sheet, the document guide is pivoted about 100.Type: GrantFiled: January 11, 1996Date of Patent: July 29, 1997Assignee: Hewlett-Packard CompanyInventors: Samuel A.

Patent number: 5598201Abstract: The invention uses two very inexpensive rotary encoders in combination--a close-coupled one (or more) for high accuracy, and a remote-coupled one for high resolution. High-accuracy information is then combined with high resolution information in a digital processing system to yield composite information that is high in both accuracy and resolution. This information can be used to establish image positioning on a print medium. The overall system cost is lower than with an equivalent single encoder. Insidious cyclical errors in the coupling system (gear train or the like) are removable without expensive high tolerances and assembly or test fixtures. Residual cyclical error due to eccentric mounting or other error in the direct-coupled encoder scale also can be substantially removed, if desired, by adding another one or more encoders reading that scale, and suitably combining the information about that scale from the different sensors.Type: GrantFiled: January 31, 1994Date of Patent: January 28, 1997Assignee: Hewlett-Packard CompanyInventors: Samuel A. Stodder, Paul J. Wield

Patent number: 5391009Abstract: A hardcopy device has various page processing steps in a printer, fax machine or the like which are actuated by a single motor which connects through a gear mechanism to drive a main drive roller, a pick roller, and automatically move a pressure plate in a feeder slot to and fro between a position of engagement holding a stack of pages against the pick roller and a position of disengagement. A reverse action of the pick roller kicks out partially picked pages into the feeder slot after the pressure plate is moved to a position of disengagement.Type: GrantFiled: October 29, 1993Date of Patent: February 21, 1995Assignee: Hewlett-Packard CompanyInventor: Samuel A.

Patent number: 4916638Abstract: A media advance system for swath-type printers for precisely positioning the media for successive swath printing. A dual photodiode line sensor is mounted on the print head. The diode active areas are separated by less than the line widths of lines printed in the media margin. Circuitry is provided to provide a signal indicative of the difference between the photocurrents produced by each photodiode. For the first swath of the page or plot, marginal lines are drawn by the first and Nth print device of the print head. Without moving the media, the line sensor is positioned over the marginal line printed by the first device, and the resulting difference signal is saved as a reference value. The media is then advanced until the same value of the difference signal is obtained from the line image of the marginal line drawn by the Nth print device. The media is then advanced a predetermined amount to precisely position the media for the next successive swath to be printed.Type: GrantFiled: April 25, 1989Date of Patent: April 10, 1990Assignee: Hewlett-Packard CompanyInventors: Robert D. Haselby, Jeffrey S. Best, Samuel A. Stodder

Patent number: 4844317Abstract: A rigid link is provided between a plot medium (14) and a position transducer (50) so that accurate plot medium advance measurement can be attained. The device (30) comprises a movable carriage (42) and an arm-like extension (38) that juts out from the carriage to the plot medium. A friction hold is made between the extension arm and the plot medium by applying a force to the extension arm normal to the plot medium by means of an electromagnet (33) which includes a coil (34), the extension arm serving as the armature. The electromagnet is located beneath the platen (12) which supports the medium on a base (32) which also supports the carriage.With the electromagnet activated, the extension arm is held against the plot medium. As the plot medium is advanced by a plot medium drive system (20), the extension arm and carriage are pulled along. Plot medium advance is stopped when the proper advance distance has been sensed by the position transducer.Type: GrantFiled: July 24, 1987Date of Patent: July 4, 1989Assignee: Hewlett-Packard CompanyInventors: Samuel A.
