Abstract: A single sheet publication binding process utilizes media having an adhesive pre-applied to the media before the media is printed or bound within a publication. A publication page, or cover, has an adhesive pre-applied, is printed, and is then aligned in a publication binder. The publication binder aligns the cover and pages of a publication one page at a time and applies a pressure to each page for a period of time that will activate a pressure sensitive co-adhesive on the page with the co-adhesive on another page, or with the co-adhesive on the cover.

Abstract: In one aspect, the invention encompasses a method of using an image forming device. A first pattern of toner is provided on a photosensitive drum of the image forming device. The toner is transferred from the photosensitive drum to an intermediate transfer belt to form a second pattern. After forming the second pattern, a bias of the photosensitive drum is reversed relative to the intermediate transfer belt and toner is transferred back to the photosensitive drum from the intermediate transfer belt to form a third pattern of toner on the photosensitive drum. In another aspect, the invention encompasses a method of detecting inaccuracies in toner placement on an intermediate transfer belt of an image forming device. A first pattern of black, magenta, cyan and yellow toners is provided on a photosensitive drum of the image forming device. The toners are transferred from the photosensitive drum to an intermediate transfer belt of the image forming device to form a second pattern.

Abstract: A system and method of providing a periodic trajectory scan path for a laser beam across a photoconductive surface in a laser printer. A preferred embodiment of the periodic trajectory for a system with a two-axis deflector includes a multiple-frequency omega wave trajectory for providing a substantially rectangular grid of available dot locations for selective laser beam pulsing. As such, a plurality of generally linear rows of dots are completed in a single scan pass of the laser beam across the surface. The periodic trajectory is provided by deflecting the laser beam with an optical beam deflector, such as an electro-optic deflector, placed between the laser and the rotating polygon scanning mirror. A preferred embodiment of the beam deflector includes a folded optical path.

Abstract: A printer responds to a media gloss measurement for improved color printing. The printer includes a gloss meter, a controller, and a print engine. The gloss meter includes a solid body having a source tube and a reflection tube each being integral within the body. An LED in the source tube illuminates a reference surface at an angle of incidence. A photo sensor in the reflection tube responds to a first reference spectral reflection from the surface at an angle of reflection equal to the angle of incidence. When a sheet of media is registered by the printer against the reference surface, the photo sensor responds to a second spectral reflection from the media. The ratio of second to first spectral reflection intensities is compared to a selected threshold to identify the media by gloss level. When motion of the media is resumed, the media wipes the reference surface to maintain the accuracy of gloss measurements.

Abstract: A system and method of deflecting a laser beam in a laser printer for providing enhanced resolution and reduced banding effects. Specifically, to enhance resolution, the laser beam is borrowed (deflected) from a white space area adjacent an image to double resolution at the edges of the image. Similarly, banding is reduced by deflecting the beam to compensate for drum rotational and translational errors. The beam is deflected using an electro-optic modulator placed between the laser diode and the scanning mirror. Encoders detect drum rotational errors and motion between the optics unit and the drum to provide a closed loop feedback system for reducing banding.

Abstract: A sealed substrate processing path has plural selectably isolatable vacuum deposition chambers along the path. A transporter carries substrates along the path and an independently controllable sputter deposition is performed in each deposition chamber on substrates therein. Substrates are loaded from a load chamber to a first deposition chamber while a vacuum is maintained in the first and load chambers. Substrates are transferred from a last deposition chamber to an unload chamber while a vacuum is maintained in the last and load chambers. Substrates are placed in the load chamber while the load and first chambers are isolated and are removed from the unload chamber while the last and unload chambers are isolated. In one embodiment, substrates travel succesively from the load chamber to first through fourth deposition chambers and then to the unload chamber.

Abstract: Apparatus is provided in which a colleting and spindle assembly for lifting and rotating a substrate mounting chassis within a high vacuum sputtering chamber is mounted. Lifting and clamping action is accomplished utilizing rolling contact between surfaces produced by rotating a minor shaft with an eccentrically mounted bearing within and relative to a major shaft. A pneumatically-actuated piston mounted on one end of the major shaft drives an internally mounted high helix screw which is prevented from rotating relative to the major shaft thereby producing linear motion of the helix screw in a helix nut resulting in rotational motion of the helix nut relative to the major shaft. The rotational motion of the helix nut is coupled to the minor shaft causing it to rotate relative to the major shaft. Once the spindle assembly has been coupled to the substrate mounting chassis, the major shaft couples rotational motion to the substrate mounting chassis from outside the chamber to inside the chamber.
