Yesterday I ran a test on my Epson SP R1900 that may or may not be relevant. It it certainly seems as such to the extent I can discern ink consumption on the ink status display screen from the printer driver. Thus I think this operation typically uses far less ink than the basic Head Cleaning operation. Then I assume that the cleaning process (however that works) 'focuses on' the nozzles that have not performed properly. In this operation, a test pattern is printed and read by some sort of photoelectric detector scan to determine which, if any, nozzles are failing to deposit ink. That was not my understanding with regard to the Epson Auto Nozzle Check and Cleaning operation. He tells us that both the basic Head Cleaning operation and the advanced Auto Nozzle Check and Cleaning operation run a full unclog cycle on all nozzles for all colors, using a substantial amount of ink, even if only a few nozzles are clogged. The narrator begins by explaining a problem with using the nozzle unclog operations provided on many printers (he uses the Epson Stylus Photo R1900 as an example).

There is a nice video that explains this feature, which has great flexibility: The printing program Qimage Ultimate contains a useful feature - the generation of special patterns intended for use in unclogging ink jet print head nozzles that have become clogged.
