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： A line scanning apparatus employing a multiplicity of linear arrays, the linear extent of which is less than the length of the scan line. To permit an entire line to be covered, the arrays are offset from one another in the direction of scan with adjoining array ends overlapped. To correct for the misalignment and redundancy introduced, the image data from the arrays is buffered until a line is completed when readout, is initiated. During readout, cross over from one array to the next is effected within the overlapped areas and the redundant data discarded.

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： Differences between an offline spectrophotometer and an inline spectrophotometer can result in differences between a hardcopy target color and a printed reproduction of that color. The inline spectrophotometer is inside of a printer and configured to measure printer output. As such, the inline spectrophotometer cannot conveniently measure the hardcopy target color. A printing error or an instrument offset can be determined and passed to a color correction module that updates the device dependent color specification associated with the given spot color. This color specification may be stored, for example, in the printer controller, and used when a document subsequently calls for that spot color, thereby providing accurate color reproduction from that particular printer incorporating that particular inline spectrophotometer.
