METHODS AND SYSTEMS FOR RECOVERY OF FAILED INKJETS
A method for recovering missing inkjets in a printhead including determining an inkjet in the printhead is not ejecting ink, purging degassed ink into the printhead, adjusting a pressure in the printhead so that ink drools out of an aperture of each nozzle of the printhead, repeatedly applying a non...

| description | A method for recovering missing inkjets in a printhead including determining an inkjet in the printhead is not ejecting ink, purging degassed ink into the printhead, adjusting a pressure in the printhead so that ink drools out of an aperture of each nozzle of the printhead, repeatedly applying a non-firing waveform at a frequency for a predetermined amount of time to the printhead while the ink drools out of the aperture of each nozzle of the printhead, and after the predetermined amount of time, adjusting the pressure in the printhead to a normal printhead pressure.
种用于恢复打印头中的未命中喷头的方法包含：确定所述打印头中的喷头不喷出油墨；将已除气油墨清除到所述打印头中；调整所述打印头中的压力，使得油墨流出所述打印头的每喷嘴的孔隙；在所述油墨流出所述打印头的每喷嘴的所述孔隙的同时，在预定时间量内以定频率向所述打印头反复地施加非激发波形；以及在所述预定时间量之后，将所述打印头中的所述压力调整成正常打印头压力。 |
