U150 error on MP600 Canon printer

I worked for a reputable refill shop and we have had a lot of troubles with the canon cli 8, especially yellows. They definately have faults. Canon will replace the particular ink cartridge for you or you can return it to the place of purchase and they will send it away and reimburse you. OR get Cartridge World to refill your cli 8's, as they will generally notice if the cartridge is no good when they reset the chip ( The chips are resettable these days.) You will find you will go home with more peace of mind then if you had a genuine.

U150 ink error fixed!

I too was getting the error for unrecognized ink cartridge. Then the little green circ board fell out of the end of the ink cartridge and it hit me that maybe if I put in the little green circ board from the old ink cartridge of the same color, then maybe the ink cartridge would be recognized. It worked! So don't throw out an ink cartridge that still has ink just because of that error and hold onto your empty cartridges in case you need the little green/gold circ boards.

This works!

Mine too... These printers are definately fucked. Keep getting the problem with the yellow cartridge and we're on our third cartridge. 100% full. £15

Canon should offer a product recall on all printers affected by this common U150 problem. I wonder though if they are even aware of it, or care. There are no forums (as far as I can see) on the Canon web site. Maybe they're clueless, and that's bad. Maybe they're NOT clueless and don't care, and that's bad too.
