CANON MP 600 ?
HAVE BEEN using non canon ink for a long time . printer suddenly will not recognise ink have bought new oem ink with new chip - all lights light up when installed but when printer checks itself it says it says not recognised - but not in any particular sequence- need help to reset- have used chip resetter on cartridges but printer seems to keep changing selection of which cartridge to reject
