Abstract: A method for operating an inkjet printhead includes identifying a number of ink drop ejections for an inkjet in the printhead to form a printed image with reference to image data corresponding to the printed image and generating control data that specify a sequence of a plurality of non-firing electrical signals to be applied to the inkjet with reference to a predetermined control sequence stored in a memory and the number of ink drop ejections. The method further includes generating non-firing electrical signals applied to the inkjet with reference to the control data and generating a plurality of firing electrical signals applied to the inkjet to eject ink drops after generating every non-firing electrical signal in the plurality of non-firing electrical signals.
