More Information
Summary:Methods and apparatus to prime a printhead assembly are disclosed. An example method includes drawing ink into a printhead assembly by operating a pump in fluid communication with the printhead assembly for a first period of time at a first speed. An amount of ink drawn into the printhead assembly during the first period is to be sufficient to cover nozzles of a die at an outlet of the printhead assembly. The example method further includes evacuating air within the printhead assembly by operating the pump for a second period of time after the first period of time at a second speed greater than the first speed.
