CARTRIDGE REPLACEMENT NOT RECOGNISED

hi,restart your printer with the printer replacement inside and wait for the error message to appear once error appear,press and hold the stop button untill the system re started.in this process the main ink detector will be reset and will recognized the new replacement cartridge

note:press and hold the stop button and never release the button until power restarted.

If you want to be able to save on your cartridge you can refill your empty cannon cartridge with ink
here a video on how to refill the cartridge.

If you refilled the cartridge, most likely the wafer chip on the ink cartridge is a self setting chip. What this means is once the ink runs out one time, the chip will either short or change a pattern to allow the cartridge to never work again (so you have to go out and buy their new ink) Some places sell a chip reset, or you can replace it will an OEM black ink.

If this all fails, than the print head (the carriage the ink sits in) is faulty

It could be you have used a refilled cartridge and the date or information inside the refill is now telling printer its not recognised.
The replacement one could be faulty (if refilled).
I have had a lot of problems with refills and now tend not to use them anymore.

Was the replacement cartridge Canon brand on a refill? Either way that style Canon printers are designed to not accept refiled printer cartridges for the 30s, 40s or 50s. It is likely that the printer deemed your cartridge not an un-used original and turned it into an inky paper weight. I would return the cartridge to where ever you purchased it and be sure to only purchase new Canon brand for that machine.

Replace color cartridge.Printer can't print without color cartridge.In your case the color cartridge is failed.

Because these a refills inks the Chip things they are full so you must replace the cartridge with a new Canon one and the fault will go. If not just replace the chip with a new one!

Then your error u150 will go.

Replace your Colour Cartridge.

replace the cartridge with a Canon as the chip has gone on the cartridge.

this is the only way around it with the mp950.

This is to stop them being refilled

I held down the stop butten for five seconds and now it seems to work fine. Perhaps this could help you.

Using replacement cartridges that come without a chip seems to be the problem I had with the Canon Pixma 510 printer they are cheaper
but if they do not show the ink levels then its inconvienent so I have but Canon products with a chip and they work perfectly.
