Patent ID: 7571973

Claim:
A fluid short management assembly for a plurality of fluid-ejection devices organized into a plurality of pairs of fluid-ejection devices comprising: one or more monitoring mechanisms to monitor one or more fluid short conditions for each of the plurality of fluid-ejection devices selected from the group essentially consisting of a fluid short over-current condition by sampling device current of the fluid-ejection device a plurality of times, determining an average device current based on the device current sampled the plurality of times, and determining whether the device current sampled any of the plurality of times is greater than the average device current by more than a threshold; a fluid short over-voltage condition by sampling device voltage of the fluid-ejection device a plurality of times, determining an average device voltage based on the device voltage sampled the plurality of times, and determining whether the device voltage sampled any of the plurality of times is greater than the average device voltage by more than a threshold; and, a fluid short over-temperature condition; and, a controller comprising a sub-controller for each of the pairs of fluid-ejection devices to turn off any fluid-ejection device of the pair of fluid-ejection devices failing any of the one or more fluid short conditions without affecting any other of the plurality of fluid-ejection devices of the pair of fluid-ejection devices not failing any of the one or more fluid short conditions.
