Abstract: For an ink-jet printer, an indication of the quantity of ink remaining gives the user useful information about when to replace a disposable printhead or ink cartridge. The invention disclosed herein provides a means for computing remaining ink and for sensing a true low-ink and out-of-ink condition. Ink is supplied to a printhead (24) by an elastic bladder (16) which is periodically refilled from an ink bag (14). The bladder is designed to collapse in a repeatable manner as ink is consumed. A sensor probe (100), which moves along the bladder's collapse axis, dimples the bladder prior to printing to initialize the collapse mode. The probe position along the axis is measured when its sensitive tip (102) touches the bladder. The difference between bladder positions before and after refill is used in an algorithm to compute the bladder's volumetric change. This is the ink consumed on each print cycle, and gives the quantity of ink remaining when subtracted from an initial value. The bladder's position is known when it refills completely, but it will not reach this position when the ink bag fully collapses from ink exhaustion. Sensing that the bladder has not extended to the full position after a refill cycle produces the true low-ink and out-of-ink indication.

Abstract: A staple hole forming apparatus including a pair of pins and a pin receptor. The pair of pins are spaced from each other a distance substantially equal to a distance between two legs of a staple. The pin receptor is positioned opposite the pair of pins relative to a sheet path through the staple hole forming apparatus. The pin receptor is positioned to mate with at least one of the pair of pins. One of the pair of pins and the pin receptor is configured to move towards and mate with the other of the pair of pins and the pin receptor causing the pair of pins to penetrate a sheet extending between the pair of pins and the pin receptor to form two holes in the sheet. Each of the two holes is configured to receive one of the two legs of the staple.

Abstract: A probabilistic input-output system is used to classify media in printer applications. The probabilistic input-output system uses at least two input parameters to generate an output that has a joint dependency on the input parameters. The input parameters are associated with image-related measurements acquired from imaging textural features that are characteristic of the different classes (types and/or groups) of possible media. The output is a best match in a correlation between stored reference information and information that is specific to an unknown medium of interest. Cluster-weighted modeling techniques are used for generating highly accurate classification results. Within the imaging process, grazing angle illumination (i.e., introducing light at an angle of at least 45 degrees to the normal of the surface being imaged) provides sufficient contrasts for distinguishing the structural features (e.g., paper fibers) of the unknown medium, but non-grazing illumination may be used when specular measurements are to be obtained.

Abstract: Systems and methods for attaching a cover to a text body to create bound documents with floating and attached spines are described. In some embodiments, a solid pressure sensitive adhesive film is applied between a cover and the side hinge areas of a text body, and a cover is bound to the side hinge areas of the text body with pressure. A solid pressure sensitive adhesive tape may be dispensed from an adhesive dispenser that includes a plug-in cartridge housing, a supply spool, and a take-up spool. In other embodiments, an adhesive sheet that includes a hot melt adhesive film and a backing is applied to the text body, with the hot melt adhesive film in contact with the side hinge areas and the spine of the text body. The hot melt adhesive is exposed in areas corresponding to the side hinge areas of the text body for attaching the cover to the text body. In one embodiment, an adhesive sheet includes a hot melt adhesive film and a backing layer that is attached to the hot melt adhesive film and has one or more slits extending in a substantially longitudinal direction. The slitted backing layer is configured to expose the hot melt adhesive upon stretching of the backing layer in a direction substantially orthogonal to the longitudinal direction.

Abstract: The present invention is a method and device for identifying recording media in a printer. The invention utilizes fine structure of the media revealed by illumination from one or more directions to distinguish among different kinds of plain papers, coated papers, such as glossy papers, and transparency films. When the medium is bond paper, by introducing light at an angle of less than approximately sixteen degrees relative to the surface, raised surface irregularities cast shadows creating a pattern rich in detail. For glossy surfaces, a high contrast image is obtained in the specular direction from normally incident illumination. The medium surface is imaged on an optoelectronic sensor to form a characteristic vector which is compared with reference vectors, corresponding to different media types, to determine the recording medium. The detection of the recording medium may then be used to change the characteristics of the printer.

Abstract: A low cost, high speed, high resolution laser printer method and apparatus for re-writable media is presented. A method for finishing of printed sheets into booklets is described. Novel mechanical operations permit the manufacture of a very low-cost, off-line booklet maker for use with desktop laser and ink jet printers. The technology can scale to medium-speed, in-line booklet manufacture. The method is novel because most of the finishing operations are performed on a sheet-by-sheet basis using precision paper positioning and a transverse tool carrier that cuts, scores, folds, punches, and staples the sheets. To form a finished saddle-stitched booklet, each sheet is cut to length determined by its sequence in the booklet and paper thickness, scored, punched (if required), folded, accumulated in a stack, and stapled. The sheet-wise method allows finishing operations to be done with low-cost tools and low actuation forces.

Abstract: A solder drop ejector is disclosed where a current through liquid solder in a channel flows in a direction opposite to the direction of current through a fixed conductor insulated from the channel. The magnetic fields generated repulse the solder toward an orifice to eject a droplet of solder. The dielectric layer separating the fixed conductor and the solder is formed of a film. The film may be made extremely thin, such as 0.1 microns, so that the necessary repulsion force generated by the oppositely flowing currents may be achieved with relatively low driving currents of 10-200 amperes. The thin dielectric film is not molded and is not required to provide mechanical support to a channel wall. Hence, the manufacturing of the resulting solder jet printhead is simplified and its reliability is improved.

Abstract: A multi-color ink-jet printing system includes a printing element for applying a precisely metered quantity of a colorless precursor in a binary or ternary chemical reaction to a precisely defined printing location on a recording medium surface. The precursor conditions the medium surface prior to application of one or more colorants to the recording medium surface to prevent recording medium cockle and curl, and to reduce dry time, while conditioning the recording medium surface for uniform dot gain independent of media composition. The precursor also immobilizes the colorants on the recording medium surface to enable one-pass, multi-color printing, while eliminating color bleed.
