PRINTHEAD WITH VARIABLE NOZZLE FIRING SEQUENCE

摘要

A printhead for an inkjet printer, the printhead comprising: an array of ink ejection nozzles; a plurality of actuators arranged such that one of the actuators corresponds to one of the nozzles respectively in order to eject ink therethrough; a drive circuitry for receiving print data from a print engine controller and distributing fire signals to the actuators; wherein during use, the array of nozzles are fired in a firing sequence determined by the drive circuitry such that the firing sequence for one line of print is different to the firing sequence for the subsequent line of print.
