Question about Canon Pixma MP500 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. I´ve got the same problem but with my black ink tank: UO71. Can you help me?
Do not buy a Cannon again, they ****! this is my last one it is a i6600P

I had the same problem and when i checked inside to see why it was not working with the cyan i saw that a sensor was the problem... it had fallen out. check it out and let me know if it is the same with yours.

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!
