ABSTRACT:
A fluid short management assembly for a plurality of fluid-ejection devices of one embodiment of the invention is disclosed that includes one or more monitoring mechanisms and a controller. The monitoring mechanisms monitor one or more fluid short conditions for each fluid ejection device. The fluid short conditions are selected from the group essentially consisting of: an over-current condition, an over-voltage condition, and an over-temperature condition. The controller turns off those of the fluid-ejection devices failing any of the fluid short conditions without affecting other of the fluid ejection devices not failing any of the fluid short conditions.
