Abstract:
1. A method for misfiring print nozzle compensation, comprising: generating a test pattern on a print medium using a number of print nozzles arranged into a plurality of columnar groups of nozzles in a printhead module of an imaging device before initiating a print job; examining the test pattern to determine whether one or more among the number of print nozzles is misfiring; identifying which of the number of print nozzles is capable of addressing one or more locations indicating misfiring of one or more print nozzles; and compensating at least partially for the one or more misfiring print nozzles by repositioning of one or more of the columnar groups of nozzles including one or more print nozzles capable of substituting for the identified one or more misfiring print nozzles in another of the columnar groups of nozzles at the one or more addressed locations on the print medium.
