After 4 years and moderate use my Canon Pixma MP550 turned suddenly and completely his service an - error code 200. Also repeatedly and most intensive cleaning the print head did not help, even with nozzles fit of kava INK. Unchanged error code 200. After some hesitation, I decided to buy a new printhead. The right decision! Age printhead out, new print head and ink cartridges new pure - the fault indicator was gone, the printers showed his usual menu. For testing purposes, I started immediately a print job, and after he printed seinenem usual preparation procedure, as if nothing had happened, completely and in best quality.
Very useful were the instructions supplied for quality assurance using the printer that also own failures in the past made clear to me (eg 1 x compl. Color printing per week). A color photo of a week in otherwise occasional use would rather strpazieren ink usage. There is for more effective processes Fortunately.
