    摘要： To print an image having a 600 dpi resolution along the horizontal axis with an ink jet printer that has a 300 dpi resolution, the method raster scans selected pixels from a selected pixel pattern. The image receiving member is then advanced a selected distance. Remaining pixels from the selected pixel image pattern are then raster scanned onto the image receiving member to visibly reproduce the image at a defined resolution.

    摘要： To print an image having a 600 dpi resolution along the horizontal axis with an ink jet printer that has a 300 dpi resolution, the method alternately examines the odd and even numbered pixel rows of the image. Odd-numbered rows are examined in a left-to-right manner while even-numbered rows are examined in a right-to-left manner. In odd-numbered rows the even numbered pixels are deleted. In the even-numbered rows, the even numbered pixels are deleted starting from the right-most pixel. After deleting the respective pixels, ink drops are fired from the ink jet printer at areas corresponding to the remaining ON pixels. This visibly reproduces the image at the 600 dpi resolution.

    摘要： The subject invention is an optical sensor detection system for a serial printer useful for the determination of alignment and misalignment of images on a sheet of print media and the correction of misalignment. The present invention includes a photoelectric sensor mounted on the carriage of a serial type printer to locate various indicator markings.In operation the sensor detects the position of a midpoint indicator when the carriage travels from right to left, and then from left to right. The positional information is then compared with the assumed mid-carriage position of the print head based upon the time of travel, that is, the predicted position of the sensor assuming no flex in the support members of the print head and no stretch of the belt driving the print head. The difference between the actual position and the assumed position is then used to derive a correction factor to the right to left and left to right printing parameters, and is used to compensate the timing of the placement of dots on the print media so that they are aligned in each pass.

    摘要： A method and apparatus for reducing intercolor bleed using pixel spot size control to improve print quality is provided. The method includes printing pixels having a first spot size in an image region having a boundary between a first color portion and a second color portion of the image by ejecting first sized ink drops from the printhead nozzles, and printing border pixels having spot sizes smaller than the first spot size in the image region by ejecting smaller ink drops from the printhead nozzles, wherein the smaller ink drops are smaller than the first sized ink drops. A printing system is provided having means for printing pixels in the region having the first spot size and means for printing border pixels having spot sizes smaller than the first spot size.

    摘要： The printing operation of an ink jet printer is controlled based on the density of the image to be printed. Using the density, a required drying time for each swath of printed matter is determined based on the image density. Also using the density, a maximum print frequency of firing the ink jets is determined. The density is determined by filtering stored print data by dividing the print data into blocks and determining a maximum number of ON pixels in a block. Such filtering enables clusters of ON pixels to be detected thus providing a more accurate determination of the density.

    摘要： An ink jet printer has a temperature sensor as a permanent part thereof to measure the temperature of printheads which are an integral part of a replaceable printhead cartridge assembly. The temperature sensor is a part of the maintenance station and senses the temperature of the printheads each time the printhead enters the maintenance station. In the preferred embodiment, the temperature sensor is spring-loaded and is located at a printhead spitting location between fixed wiper blades and the capping location in the maintenance station, so that temperature is sensed each time the printhead enters and leaves the maintenance station to eject nozzle cleaning droplets onto a collection surface at the spitting location to clean the printhead nozzle face by the wiper blades, or to cap the printhead nozzles. To facilitate good thermal contact, a recess is provided in the heat sink upon which the printhead resides for entry by the spring-loaded temperature sensor.
