A client of mine (I'm a computer repair guy) gave me an old Pixma MX-347 they no longer needed.
The old cartridges (810/811) are almost empty, but still work/print. I want to use the printer, so I searched for new cartridges.
Online, I determined that Canon no longer makes 810/811 cartridges, but *according to Canon*, the 510/511 cartridges are the right ones to use for this model.
So, I went to the store, found the cartridges, confirmed that for my model (Pixma series MX-340), and bought it.
It doesn't work. I get the error message "Check Ink U140". I've tried to reset the device. I've re-inserted the old ones and they still work. But not the new ones.
