Abstract:
In a droplet ejection system using a printhead having an array of ejectors arranged in rows and columns, where operation of each ejector is individually controllable, a method of minimizing cross-talk errors between ejectors adjacent to each other in a same row, the method comprising:selecting first and third ejector in a selected row of the printhead; identifying the first and third selected ejectors as one of odd or even ejectors of the selected row; generating a first firing sequence for the first selected ejector based on the first selected ejector being identified as the one of odd or even; selecting a second ejector in the selected row of the printhead, the selected row being the same row as the row of the first and third selected ejectors and the second ejector being adjacent the first ejector, and the third ejector being adjacent the second ejector; identifying the second selected ejector as an odd or even ejector of the selected row; generating a second firing sequence for the second selected ejector based on the second selected ejector being identified as odd or even; and generating a third firing sequence for the third selected ejector based on the third ejector being identified as one of odd or even, wherein the first, second and third firing sequences cause the first and third ejectors to be active when the second ejector is inactive, and the first and third ejectors to be inactive when the second ejector is active.
