摘要

Disclosed is a method of operating an inkjet printer (10) having one or more inkjet print cartridges (12) installed in the printer (10), wherein the printer (10) 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 (10) when a predetermined number of possible resistors (44) on the print cartridge (12) are firing during a given period of time, determining an actual number of resistors (44) firing on the print cartridge (12) 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 (10) using the selected operating voltage setting for the print cartridge (12).
