Assignee:
Xerox Corporation - Stamford CT
International Classification:
G03G 1500
US Classification:
399395, 399394
Abstract:
A copy machine having a high accuracy sheet registration system for precise placement of images on each copy sheet. The copy machine includes sensors with charge coupled devices (CCDs) that detect the sheet positions in two dimensions within the machine, and detect sheet arrival times at various positions with the machine. Using this detected information, the copy machine employs a multi-stage process to bring the sheet into contact with a color image moving on a photoreceptor belt, in synchronism with the position and speed of the image on the belt. The copy machine also monitors its own condition and makes predictions about needed preventive maintenance, to instruct personnel to service the machine before the machine fails.

International Classification:
G03G 1516
US Classification:
399 66, 318 9, 399 75, 399307
Abstract:
Apparatus and method for controlling picture quality in a transfuse xerographic machine has independent velocity control of image transfer and transfuse belts or rollers when they are disengaged from each other and a common velocity control when they are engaged with each other. The machine can be a monochrome or color copier or printer. Various rollers can be the drive and/or the encoder rollers.
Stitching And Color Registration Control For Multi-Scan Printing

Assignee:
Xerox Corporation - Stamford CT
International Classification:
A41J 3407
US Classification:
347 37, 347 19
Abstract:
An apparatus and method are provided for the use of an optical sensor to determine the position of a printing device relative to a piece of paper or a paper-handling surface. The optical sensor reads marks to detect movement and/or direction of movement or spacing of imprints on the paper. Benefits include swath stitching calibration, color to color registration, producing printing device alignment data and generating information for printing device firing signals. The present invention is applicable to a wide field of printing technologies, including, but not limited to, acoustic ink printing, thermal ink jet printing, piezo ink jet printing, ionographic printing and a variety of other printing technologies involving the need for positioning a printing device relative to a piece of paper.
Color Image Registration Based Upon Belt And Raster Output Scanner Synchronization

Assignee:
Xerox Corporation - Stamford CT
International Classification:
B41J 2385
US Classification:
347116, 347235
Abstract:
Color electrophotographic printers having latent image positions synchronized with start-of-scan signals. A laser source projects a laser beam onto a multifaceted rotating polygon that sweeps that beam in a scan line across a moving photoreceptor. A start-of-scan detector produces start-of-scan signals when the laser beam is in position to write a scan line. A belt sensor produces belt signals when indicia on the photoreceptor passes a reference position. A controller receives the belt signals and the start-of-scan and then adjusts the photoreceptors rotational velocity such that the belt signals are an integral multiple of the start-of-scan signals. To reduce the impact of drive roller eccentricities on belt signal to start-of-scan signal timing, the perimeters of photoreceptor roller elements are sub-multiples of the photoreceptor length.
Printer Sheet Lateral Registration And Deskewing System
Lloyd A. Williams - Mahopac NY Joannes N. M. deJong - Suffern NY Matthew Dondiego - West Milford NJ Michael J. Savino - Tappan NY
Assignee:
Xerox Corporation - Stamford CT
International Classification:
B65H 702
US Classification:
271228
Abstract:
A sheet registration system, especially for printers, with a lower cost and lower mass-movement system for both sheet deskewing and transverse registration repositioning of the sheets in the same integral system, especially for higher speed printing. Only one main drive motor can drive both of the two spaced apart sheet feeding nips, together with a much lower power, and lower cost, deskewing differential drive system for providing the relative differential angular movement of the two spaced sheet feeding nips to achieve the desired amount of sheet deskewing movement, without interrupting the forward feeding movement of the sheet. Also disclosed are extensive further reductions in the component mass of the lateral translation movement for lateral sheet registration.

Abstract:
A sheet registration system, especially for printers, with a lower cost and lower mass system for sheets deskewing, and optionally also compatibly providing transverse registration repositioning of the sheets. Mechanisms are disclosed which need only one main drive motor to drive both of the two spaced apart sheet feeding nips, together with a much lower power, and lower cost, deskewing differential drive system for providing the relative differential angular movement of the two spaced sheet feeding nips to achieve the desired amount of sheet deskewing movement, without interrupting the forward feeding movement of the sheet.
Low Force Lateral Photoreceptor Or Intermediate Transfer Belt Tracking Correction System

Assignee:
Xerox Corporation - Stamford CT
International Classification:
G03G 1500
US Classification:
399165, 19881003, 198814, 399162
Abstract:
In a printing system in which a rotatable print image bearing belt is mounted on at least one axial belt roller, and the belt must be maintained in a desired substantially consistent lateral registration to maintain image quality, the lateral misregistration of the belt is sensed and a low and substantially constant lateral positional corrective force is applied to the belt in response to the sensing of the lateral misregistration in one of the two directions axial of the axial belt roller for at least one complete rotation of the rotatable print image bearing belt, the low and substantially constant transverse corrective force having a force level sufficient to provide the desired substantially consistent lateral registration of the print image bearing belt.
Method And Apparatus For Using Fast Fourier Transform Feedback To Compensate For Non-Linear Motion

International Classification:
G05B 1302
US Classification:
700 45, 700261
Abstract:
A non-linear control (NLC) system for controlling performance of a device. The NLC system comprises a controller system and a first feedback compensator connected to the controller. The first feedback compensator compensates for linear error performance of the device; the second feedback compensator compensates for non-linear error performance of the device.

Gai Waterhouse and Damien Oliver overcome their personal battles to winning ...
She made winning the Melbourne Cup with Fiorente a meticulously plotted obsession. She called on Lloyd Williams, T.J.'s old mate, for tips about training Cup winners, never blas enough to think she knew it all.
Australian property magnate Lloyd Williams was widely tipped to win a fifth Melbourne Cup as an owner of six horses in the field but was left disappointed as Fawkner was the pick of the bunch finishing sixth.

Heineken Cup Wrap: Glasgow save some pride as Edinburgh's slump continues
In the pool's dead-rubber fixture, Cardiff Blues recorded a 26-14 win over fellow-strugglers Sale Sharks at the Arms Park. Lloyd Williams and Michael Paterson scored for the home side, while Tommy Taylor and Aston Croall both got tries for the Sharks. But overall there was little to get excited abou
Fiorente up the middle, they might be the chances. Glencadam Gold tackled by Green Moon. Green Moon with andecisive move in the 200. Fiorente with a late challenge. Green Moon now at the 100. He's just clear and Green Moon for Lloyd Williams wins the cup. By a length Fiorente, Jakkalberry ran third.
