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： To accurately position printheads (C,M,Y,K) of an inkjet printer 100 in the capping area of their service station (130), the position of service station insert members (e.g. 130K) is determined by an optical sensor (117) detecting a through hole (132K) in the cartridge lid (131), and the separation (j) of the optical sensor and the printheads (e.g. K) is precisely determined. The separation (j) is determined by using the printhead nozzles to print lines (144,146) in the directions of the scan and media axes, scanning the lines with the optical sensor (117), and calculating from the results the separation (j). The results of locating the four reference holes (132C, 132M, 132Y, 132K) of the service station insert members may be averaged.

摘要： A method for servicing an inkjet printhead without removing the printhead from a carriage of the printer, wherein a controlled pressure differential is generated across the nozzle plate of the printhead to cause the formation of a controlled puddle of ink on the outside of the nozzle plate. Ink is then fired into the puddle through the nozzles of the printhead. The puddle may then be drawn back into the printhead through the nozzles. Alternatively the puddle is generated, is maintained for a predetermined period of time and then is withdrawn into the printhead without ink being fired from the nozzles.
