Abstract
Systems and methods are provided for enhanced flushing of printing systems. One embodiment is a printing system that includes an ink flushing controller. The ink flushing controller is able to identify an overlap region wherein nozzles at adjacent printheads of a marking engine overlap along a widthwise direction, to detect primary nozzles that print image data within the overlap region, and to detect overlap nozzles that do not have firing instructions to eject ink within the overlap region. The ink flushing controller is further able to analyze nozzle firing data for each overlap nozzle to determine inactive firing spans for each overlap nozzle, and in response to determining that an inactive firing span for an overlap nozzle exceeds a threshold, to generate a firing instruction directing the overlap nozzle to eject ink.
