I have this printer and after 1000 pages the print head is already going crazy and no longer prints cyan correctly. I looked for the Canon QY6-0091 print head in Switzerland, but no chance. If you're lucky, you can find it on Ebay or Aliexpress. And something else about another Canon printer: I scrapped 4 (!) Canon G4511s in our family because I couldn't find any print heads. Nothing else ever broke on these printers other than the print head! I'm beginning to wonder if this is Canon's strategy, that we should buy a new printer after 1 to 3 years because we can't get print heads. How much scrap could be avoided if you could buy the print heads and at reasonable prices. I will now probably order one from Aliexpress for a whopping CHF 134. Or preferably 3 at once, because we have 3 Canon printers in the family where this print head fits. A friendly greeting to the throwaway society.
