Abstract:
A method for determining a turn-on voltage for an inkjet printer pen comprising:for each set of nozzles of a plurality of sets of nozzles of the inkjet printer pen, firing the set of nozzles at each of a plurality of voltages to obtain a voltage-value curve for the set of nozzles; determining a nozzle turn-on voltage for the set of nozzles based on the voltage-value curve for the set of nozzles, the nozzle turn-on voltage being less than an upper plateau voltage of the voltage-value curve; and, determining the turn-on voltage for the inkjet printer pen based on the nozzle turn-on voltage of the voltage-value curve for each set of nozzles, by selecting a maximum nozzle turn-on voltage of the nozzle turn-on voltages of the voltage-value curves for the sets of nozzles as the turn-on voltage for the inkjet printer pen.
