| Zusammenfassung: | The disclosed invention relates to ink jet printing systems, and more particularly to increasing the usable life of ink firing heater resistors.
An ink jet printer having an ink delivery system that allows air to be absorbed by ink that is being delivered to an ink jet print cartridge that includes a thermal printhead, so that ink delivered to the printhead has an air saturation level of at least 30%. The dissolved air reduces damage to heater resistors of the thermal ink jet printhead that would otherwise be caused by the in rush of ink after an ink drop is fired. |
