Patent ID: 7918527

Claim:
A method for use with an imaging apparatus that mounts a printhead having a plurality of ink jetting actuators formed on a substrate that correspond to a plurality of ink jetting nozzles, comprising: determining a resistance associated with said printhead; accessing a memory having stored therein a plurality of individually selectable fire pulse energy values; selecting a first fire pulse energy value from said plurality of individually selectable fire pulse energy values based on said resistance that was determined; and using said first fire pulse energy value for actuating at least one of said plurality of ink jetting actuators during a printing operation, wherein the determining said resistance includes determining a first resistance associated with a resistive device separate from said plurality of ink jetting actuators; and determining a second resistance associated with at least one of said plurality of ink jetting actuators; and wherein the selecting includes using said first resistance to identify a range of fire pulse energy values within said plurality of individually selectable fire pulse energy values; and using said second resistance to select said first fire pulse energy value from said range of fire pulse energy values.
