Abstract
A liquid ink printer, depositing ink drops to form an image, including a pagewidth printbar, movable to print a complete image when defective nozzles of the printbar are identified. A positioning device, coupled to the pagewidth printbar, positions the printbar at a plurality of discrete locations, to move a functioning nozzle to the location in the image where the defective nozzle should deposit drops of ink. Defective nozzles are identified by the printer control mechanism and a user is given the option to fix the image through a user interface where the printer is directed to fill in the missing information of the image. Defective nozzles can also be identified by printing a test pattern which identifies to a user which of the nozzles are non-functioning. The user then inputs this information to the printer.
