Abstract
A system for compensating for non-functional ink cartridge ink jet nozzles is provided. The system includes an ink jet compensation system that receives ink jet nozzle failure data, such as each nozzle that is clogged or damaged, and that generates nozzle correction data, such as a nozzle to fire instead of each failed nozzle for a given print pattern or a nozzle firing sequence that compensates for the failed nozzle, such as by printing at that location during a subsequent or previous printer head pass. An ink control system receives the nozzle correction data and image data and generates printer control data, such as by receiving image data in a standard format for printing and modifying the printer control data that would be generated if all ink jet heads were functioning properly to include the nozzle correction data.
