I've had this MP760 for three years and it has printed beautifully in the past. Now it won't print magenta. I've change cartridges and am only using Canon ink. I've cleaned the print head by soaking in alcohol and blowing it out with high pressure air. I've also done all the maintenance functions. When I do a nozzle check, it prints all the colors without any flaws however the intensity is about a two out of a ten. When I print a photo on glossy paper it seems to print fairly well except it doesn't print any magenta. My feeling is that it may have something to do with the circuitry and not the print head. The nozzle check shows two levels of magenta consistent with the other colors. The 3eBK works great. All others are week in color level including 6BK.
Any suggestions would be greatly appreciated.
