US 2016/0107438 A1 · PRINTER OPERATION FOR EJECTION OF PURGING DROPLETS OF A PRINTING FLUID

Abstract

Operation of a printer for printing an image is described herein. It is determined whether ejection of imaging droplets of a print fluid via a set of nozzles for printing an outstanding image portion is sufficient for preventing clogging of the set of nozzles. Upon determining that ejection of imaging droplets for printing the outstanding image portion is sufficient for preventing clogging of the set of nozzles, printing is performed by ejecting only imaging droplets of the print fluid via the set of nozzles. Upon determining that ejection of imaging droplets for printing the outstanding image portion is not sufficient for preventing clogging of the set of nozzles, a servicing procedure is to be executed of to eject purging droplets of the print fluid via the set of nozzles.

A method of operating a printer for printing an image, the method comprising:

printing over a print swath for reproducing a portion of the image, wherein if ejection of imaging droplets of a print fluid via a set of nozzles for printing an outstanding image portion is above a selected droplet number, the print swath is printed by ejecting only imaging droplets of the print fluid via the set of nozzles, and
if ejection of imaging droplets of the print fluid for printing an outstanding image portion is below the selected droplet number, printing the print swath includes ejecting purging droplets of the print fluid via the set of nozzles.

A computer software product comprising a tangible medium readable by a processor, the medium having stored thereon a set of instructions for operating a printer for printing an image, the instructions comprising:

(a) a set of instructions which, when loaded into a memory and executed by the processor, causes determining whether ejection of imaging droplets of a print fluid via a set of nozzles for printing an outstanding image portion is sufficient for preventing clogging of the set of nozzles;
(b) a set of instructions which, when loaded into a memory and executed by the processor, causes, upon determining that ejection of imaging droplets for printing the outstanding image portion is sufficient for preventing clogging of the set of nozzles, printing by ejecting only imaging droplets of the print fluid via the set of nozzles;
and
(c) a set of instructions which, when loaded into a memory and executed by the processor, causes, upon determining that ejection of imaging droplets for printing the outstanding image portion is not sufficient for preventing clogging of the set of nozzles, execution of a servicing procedure to eject purging droplets of the print fluid via the set of nozzles.
