摘要： There is provided a method for determining the end of life of a pen having a printhead with a plurality of nozzles. The method includes performing a drop detection on the printhead to check if any nozzle of the printhead is malfunctioning and storing the result of the drop detection together with the results of previous drop detections to keep a history of the health status of each nozzle. The method also includes evaluating the history of the health status of each nozzle of the printhead, and deciding whether or not to mark the pen as an end of life pen.

摘要： A method for servicing an inkjet printhead effects recovery against a particular printhead failure mode via implementation of a printhead servicing routine including, but not limited to, a bubble recovery routine, a contaminant purging routine, and/or a (standard) printhead servicing routine. In a preferred embodiment, the method for servicing an inkjet printhead takes into consideration nozzle health data, diagnostics, or the like. In a preferred embodiment, a bitmap or mask is employed to control firing of the nozzles during the servicing of the printhead. In a preferred embodiment, the servicing method includes the step of: firing the printing nozzles in a manner tending to force contaminants at the printing nozzles toward one end of the printhead. In another preferred embodiment, the servicing method includes the steps of: providing an inkjet printhead with larger-sized sewage nozzles at its edges; firing the printhead nozzles in a manner which forces contaminants to the edges; and firing the sewage nozzles to expel the contaminants.

摘要： An arbitrary 3D or 2D shape is formed by construction from colorant in a volume—which may be cylindrical, annular, or of arbitrary cross-section, depending on form of the invention. In some forms, a 2D-extended array of colorant-ejecting nozzles is disposed in a particular linear direction relative to the volume, and a programmed processor controls ejection of colorant from the nozzles to pass through the volume. A 2D colorant-retrieving frame (ideally back-to-back with the array) is disposed in a second linear direction opposite to the one particular direction, from the array, to recover the colorant and thus erase the image—which can then be refreshed, with animation changes if desired, by the writing array. Colorant is moved through the volume by gravity, or by continuous ejection of material from the array and suction at the frame to form a suspending fluid flow—the array moving at equal but opposite velocity so that the image is stationary. The frame is a passive sump for colorant recovery, or has a pump for returning colorant to the array for reuse—in which case the array best ejects colorant of plural properties and the device has filters to separate retrieved colorant by those properties. In some forms, colorant is stroboscopically lighted to display apparent motion of an image element. A force field can be used to control, or help control, colorant position after ejection.

摘要： A method for correcting deviations from the normal performance of the service station by adapting the level of servicing a printhead receives based upon the age of the service station. For relatively newer service stations, the service stations may be caused to perform relatively less servicing operations on the printheads to thereby conserve ink and relatively increase the life of the service station and the printheads. For relatively older service stations, the service stations may be caused to perform relatively heavier servicing operations on the printheads to substantially compensate for the deleterious effects arising from the aging of the service station.
