    摘要: A ink jet printer having a reciprocating printhead with a single jet to print full pages of information on a recording medium by printing contiguous swaths of information. The recording medium is stepped a distance of one swath height after each swath is printed. A height control sensor is located on one side of the recording medium to receive periodically one or more sweeps of test droplets. The height control sensor has upper and lower pairs of photodetectors to detect droplets passing thereby and to produce differential sensing signals which identify the droplet having a trajectory closest to the desired trajectory. By determining the number of droplets between the identified droplets, the interdroplet spacing and drift of the droplet trajectories is monitored. In response to the height control sensor signals, the printer controller with associated circuitry adjusts the operating parameters of the printer to correct and to maintain the desired droplet trajectories and interdroplet spacings.

    摘要: An improved continuous stream ink jet printer is disclosed that conducts pagewidth printing via an array of fixed nozzles which direct droplets towards a moving recording medium. Each nozzle is assigned a segment of a printable line that extends across the entire width of the recording medium. The droplets from each nozzle are charged with printing information and fanned along its segment to specific pixels locations or to a gutter for recirculation. Distance sensing sensors are located below the droplet trajectories, parallel to the recording medium surface and perpendicular to the direction of movement of the recording medium. The distance sensing sensors periodically produce signals representative of the actual throw distance of the droplets and compare the signals indicative of the actual throw distance to a signal representative of the distance from the nozzles to a predetermined printing plane. The comparison signals are sent to the printer controller which adjusts the droplet trajectories in response thereto to correct the droplet placement errors that would be caused by variations in the throw distance produced, for example, by wrinkles in the recording medium or dimensional tolerance variations in the recording medium transport system where the printing occurs.

    摘要: An improved ink jet recording interlace strategy. Sequentially generated ink droplets directed to a recording medium are first charged and deflected by a uniform electric field. The charge sequence on the droplets is such that the droplets are separated by the electric field as they travel toward the medium thereby reducing electrostatic and aerodynamic interactions between droplets. The separation of droplets conforms to an interlace scheme wherein droplets directed to closely adjacent recording medium locations are separated by a number of droplets whose placement of said medium conforms to a multi-level interlace such that the scan direction of the number of droplets is disrupted at least once. In this way, sequentially generated droplets are directed to non-sequentially pixel locations in non-sequential interlace portions of the total number of adjacent pixel locations assigned to a particular nozzle.

    摘要: A control system for controlling the size of the image produced by pixels generated by a raster scanner employing a binary rate multiplier for image size control along the X-axis, the multiplier being programmed to the size image desired to vary the frequency of the pixel clock signals output by the multiplier, together with a control flip-flop astride the image pixel stream and driven by the multiplier clock signals to speed up or reduce the rate at which image pixels are output. For image size control along the Y-axis, a phase lock loop is provided for controlling scanning carriage speed in response to the frequency of the signals output by a programmable frequency generator.

    摘要: An ink jet printer is disclosed employing a row of multiple ink jet nozzles aimed at a moving target or copy sheet. Each nozzle has a separate charging electrode associated with it but all the nozzles share a pair of common deflection plates that divert charged droplets over a shared gutter toward the target. Uncharged droplets go into the gutter. An electrostatic lens is shared by all the nozzles being positioned in the path of the charged droplets deflected toward the target. The lens aligns or focuses charged droplets from all the nozzles to a focus line on the target despite misalignment of nozzles relative to a print line on the target.

    摘要: An ink jet printer is disclosed of the type wherein a plurality of nozzles emit parallel streams of droplets toward a target. Each nozzle has a charging electrode to charge droplets selectively depending upon whether a particular droplet is intended for the target or a gutter. A pair of deflection plates span the paths of the droplet streams and deflects the charged droplets according to information to be printed. A multiple field electrostatic lens is used to align charged droplets from different nozzles to a common line on the target despite misalignments between nozzles relative to the common line.

    摘要: The present application provides a mixed resolution, interleaving-based, cross-channel data flow and data format for a printer image path. The architecture provides pixel data for a colorant of a given writing channel at its nominal (full) resolution, while pixel data for other colorants is provided at lowered resolution. Pixel data for a primary channel at its full resolution is interleaved with data for other secondary channels at lower resolution. Known sub-sampling or compression techniques can be used to lower the resolution of the secondary channels. The data at the different resolutions is generated by the digital front end (DFE), which distributes the data for each writing channel at the time it is needed. Preferably, the low resolution data is sent first to the writer, followed by high resolution data, so that data buffering is minimized.

    摘要: Systems and methods are described that facilitate distributing a raster image processing task for an input file (e.g., an electronic document) across a plurality of nodes (e.g., computers) in a network. The input file is received at a first node, which becomes the controlling node and splits the pages of the input file into interleaved chunks such that adjacent pages are allocated to different chunks (i.e., no chunk contains adjacent pages in the document). Chunks are then assigned to different nodes for concurrent raster image processing. Once complete, the processed pages are returned to the controller node, which logically orders the pages into their original sequential order, and outputs the logically ordered, raster image processed pages to a printer, where they are printed.
