Abstract
An inkjet printhead for a printing device includes a fluid reservoir operatively disposed within the printhead and a pressure regulation system in fluid communication with the fluid reservoir. The inkjet printhead also includes a nozzle plate having at least one nozzle, wherein the nozzle is in fluid communication with the fluid reservoir; as well as a vent port in fluid communication with the pressure regulation system. Further, the inkjet printhead for a printing device includes a passive vent in fluid communication with the vent port. The passive vent is configured to dissipate air pressure accumulated in the pressure regulation system during priming. The passive vent provides a controlled decay time for the priming air pressure.
