Abstract
An apparatus enables a printer to identify neighboring inkjets to compensate for inoperative inkjets with reference to different search patterns. The apparatus includes a plurality of mutliplexers, a memory, a decoder, and a controller. The multiplexers are operatively connected to the memory to receive data that selects one of a plurality of image data pixels on the inputs of the multiplexers. The outputs of the multiplexers are concatenated in a predetermined order and the decoder identifies a highest priority image data pixel available for inoperative inkjet compensation. The controller operates the memory to output the data stored at the plurality of storage locations in a first sequence to enable the multiplexers to output the image data pixels in the predetermined order for the decoder.
