摘要： Systems, methods, software for monitoring usage of a recording medium in an image forming apparatus. In one embodiment, a usage monitor receives a raster image, and identifies thresholds that distinguish different intensity levels reproduced by different drop sizes of the recording material. The usage monitor identifies a set of pixel values for a block of pixels from the raster image, performs a vectorized comparison of the set of pixel values to each of the thresholds to generate sets of comparison bits, determines a number of set bits in each of the sets of comparison bits, and updates a threshold counter for each of the thresholds based on the number of set bits. The usage monitor may then compute drop counts for different drop sizes based on the threshold counter for each of the thresholds.

摘要： Systems and methods are provided for adaptive ink flushing of a printer. One embodiment is an apparatus that includes an adaptive ink flushing controller configured to obtain nozzle firing data for a nozzle of a printhead, to analyze the nozzle firing data to determine an inactive firing span of the nozzle, and, in response to determining that the inactive firing span of the nozzle exceeds a threshold, to transmit a firing instruction for ejecting ink.

摘要： A method is described that includes defining a window of one or more consecutive pixel values in a linear array of pixel values of an image. The defining includes adding a pixel value in the linear array to the window so long as the pixel value does not deviate from the pixel values that exist within the window to a degree that causes a threshold value to be exceeded, and, wherein the threshold value decreases as the size of the window increases. The method also includes encoding the window of pixel values with a value determined from pixel values within the window and the number of pixel values within the window.
