CONTROL EJECTION OF INK DROPS TO RESPECTIVE REGIONS IN THE SPITTOON

摘要

A method of maintaining nozzles of a printhead includes periodically moving a printhead having a plurality of nozzles toward a spittoon, and ejecting a plurality of sets of ink drops from the nozzles of the printhead to the spittoon mode. The method also includes controlling the ejecting of the plurality of sets of ink drops from the nozzles of the printhead to the spittoon by the control module. Consecutive sets of ink drops received by the spittoon are received by different sets of regions of the plurality of sets of regions within the spittoon.

1. A method of maintaining nozzles of a printhead of a printing system, the method comprising:
periodically moving a printhead having a plurality of nozzles toward a spittoon; ejecting a plurality of sets of ink drops from the nozzles of the printhead to the spittoon; identifying a plurality of sets of regions spaced apart from each other within the spittoon to receive respective sets of ink drops ejected from the printhead; and controlling the ejecting of the plurality of sets of ink drops from the nozzles of the printhead to the spittoon by the control module such that consecutive sets of ink drops received by the spittoon are received by different sets of regions of the plurality of sets of regions within the spittoon.
