SYSTEM AND METHOD FOR COMMENCING PRINTING OPERATIONS IN AN INKJET PRINTER

A method of operating a printer iteratively performs printhead purges and test pattern analysis until either every printhead has a number of inoperative inkjets that is less than a predetermined threshold or a maximum number of iterations is reached. An error message is generated for each printhead...

Zusammenfassung:	A method of operating a printer iteratively performs printhead purges and test pattern analysis until either every printhead has a number of inoperative inkjets that is less than a predetermined threshold or a maximum number of iterations is reached. An error message is generated for each printhead having a number of inoperative inkjets that is greater than the predetermined threshold. The iterative performance of the printhead purges and test pattern analysis is performed automatically prior to the commencement of printing operations with the printer to remove subjective and time-consuming analysis by a printer operator.
