Abstract (en)
Based upon the analysis of print data for a printing element of an inkjet printhead, the printing element's actuating means are left inactive (not driven) if the print data does not require the printing element to eject an ink drop. Successive occurrences of such events provide a continuous period of inactivity for the printing element, i.e. a period of rest allowing the ink in the printing element and the printing element itself to recover from the excitations enforced by preceding drop ejection processes. Periods of inactivity of a printing element are interrupted at regular time intervals by driving the printing element's actuator with a precursor signal to prevent latency problems associated with inactive printing elements.
