Varying the operating energy applied to an inkjet print cartridge based upon the operating conditions

Abstract

Disclosed is a method of operating an inkjet printer having one or more inkjet print cartridges installed in the printer, wherein the printer is capable of operating under varying operating conditions and in a plurality of different printmodes, including obtaining a value for the common parasitic resistances and a base operating voltage setting for the inkjet printer when a predetermined number of possible resistors on the print cartridge are firing during a given period of time, determining an actual number of resistors firing on the print cartridge during the given period of time, adjusting the base operating voltage setting to a selected voltage setting based on the results of said obtaining step and said determining step and operating the printer using the selected operating voltage setting for the print cartridge.
