ABSTRACT:
Methods and apparatus for adding pages to a sequence of imprinted images used for flushing of inkjet features and then discarding the added pages following imprinting of the added pages. Features and aspects hereof within a printing system automatically insert additional pages (flush pages) in a sequence of imprinted page. The inserted pages are used for flushing ink-based nozzles (e.g., inkjet nozzles). The frequency of flushes and the volume of ink to be flush at each opportunity may be determined by automated features hereof based on statistics regarding operation of the printing system or may be statically pre-determined. Post-processing features (e.g., paper handling features) may scan the pages for marks identifying a page as a flush page inserted for flushing and may discard the added pages so identified.
