The new print head as hoped the fatal, not bypassable error B200 resolved after the old printhead (after only 3 years rather below-average use) obviously had given up the ghost; a Deep Cleaning DK described the Internet brought no remedy. Annoying is, of course, the high price, but already you get almost a new printer. I took the risk of an unsuccessful exchange and have, if the new DK should keep a reasonable time because, lucky. However, the next printer will definitely be no more Canon; it seems to me, here is planned Obsolesenz at work and does not have to also support yet.
