Abstract
A method of detecting a defective nozzle within a nozzle array, may comprise grouping each nozzle with a number of other nozzles within the nozzle array, measuring fluid output from each group of nozzles with a fluid detector, individually regrouping each nozzle within a group of nozzles whose fluid output is detected as not being commensurate with the amount of fluid that should be ejected from that group with a number of known non-defective nozzles to form a number of subsequent groups, and measuring fluid output from the subsequent groups of nozzles to determine which nozzle among the subsequent groups of nozzles is defective.
