Abstract
A system and method to provide pressure to de-prime a printhead. An image forming device comprises an ink reservoir that contains ink and provides the ink to a printhead. When a fault condition is detected that indicates a likelihood of a solidifying of the ink, the printhead is de-primed by applying pressure to the printhead to purge the ink from the printhead. The fault condition comprises any of a loss of power, a power-down process, or a printhead temperature being less than or equal to a threshold temperature.
