The printer cleans more than extensively and often takes a short break before he again cleans. As I've found with hindsight the same problem with other owners, I assume that this is so intended by the manufacturer. And cleaning is unusually loud. My printer was rarely used. So far I have printed about 30 pages. All prints in black and rarely a complete page described. Almost after every page he had to clean again. The level of all cartridges has dropped to about 10%. Consider that I have only printed black. Why are the other cartridges also nearly empty? My mistake was to assume that this printer can print on both sides. In this day and age this should, in my opinion, actually be self-evident. My old HP Deskjet 6127, from about 2002 on both sides can print, has a very long breath, as regards the level of the cartridges and is more quickly when printing.
