Question about Canon PIXMA MP830 All-In-One InkJet Printer
Please help! Our MP830 was new about 4 months ago and we have now changed all the ink tanks at different stages as they ran out. We are using Canon refills but the yellow tank comes up with either the UO71 or the U140 message. It very occasionally works but these times are few and far between. Any ideas? Many thanks.
Had the same error after replacing my black ink om my MP830.(UO71) I Put some Methylated Spirits on a cotton tip and gently cleaned the cartridge chip (allow it to air dry). This fixed my problem!

I'm having the same problem and its not the cartridge. I've replaced several and I'm still having problems. Piece of junk.

Ah, so it is the cartridge, I didn't want to waste one by replacing it and finding it was still stuffed. Thanks for that, looks like I'll have to get a new cartridge!

My wife sorted this one for me. The black cartridge flashed and the UO71 error message appeared. She found that one of the other cartridges (Magenta) also had a black chip! In fact, the magenta cartridge was also flashing. After replacing the magenta chip, everything was fine again. In this context, I guess that the apparently nonsensical error message was correct: there were two cartridges (well chips, at least) of the same colour.

I had replaced my 830 and intended to discard it after two black ink tanks would no longer be recognized after repeated tattempts. I tried a third and it has been recognized. Canon's quality control must be almost nonexiatant because the odds againts two defective tanks from randoms sources at random should be in excess of a sixty character pass word. D.D.

I replaced the flashing ink cartridge with a new one and it's been fine ever since. Keep your dockets and if there is a problem tell the store to send it back to Canon. Mine did and we're cruising!
