The Canon iP3000 runs obsessive cleaning cycles whenever it is used after even just a few hours of inactivity. Although some of the colors are mixing, cleaning is not the solution, and often those colors are not even being used at such times. Even nozzle checks trigger obsessive cleaning. Sometimes opening the cover and closing it before use prevents the cleaning cycles, but often times it does not. Is there a reliable procedure to prevent the obsessive cleaning that burns through brand new genuine cartridges?
