Abstract: Methods of priming formulation delivery devices include providing a formulation cartridge, inserting the formulation cartridge into a handle of the formulation delivery device, and initiating a priming sequence which simultaneously pumps a first formulation and a second formulation from the formulation cartridge for a first time period such that the first formulation and the second formulation pass from the formulation cartridge, through a pump, and exit a nozzle assembly of the formulation delivery device.
