Question about Canon Pixma MP500 All-In-One InkJet Printer
My printer was working fine before I moved, but when I re plugged it in (not having changed any of the cartridges) it came up with error UO71 "more than on eink tank of the following color is installed".
Having same problems here. Sometimes I take out cartridges and put them back and the error message goes away and sometimes I turn it off and back on but unfortunatley not all the time does this help, grrrrrrrrrrrrr

Error code U071 is a faulty cartridge - it should be flashing in error state. Just buy a new one and all should be sweet then send your faulty one with a small description of error to Canon Consumer Returns with a return address & contact number and they will send you out a new one.

I am also getting this error message. For a few days I could take out the offending cartridge and the printer would forget for one printing and then go back to telling me that two of the same cartridges were installed. HELP! I am about to chuck it out the window, though I believe CANON should send us all new ones.
