Canon Pixma MP500 UO71 error

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".

    getting error message U071 about multiple black ink cartridages

  • hrfusion1981 Jul 06, 2008

    everything i try is a temporary solution, and now nothing works...
    i guess i need to buy a new ink cartridge....
    i'll be sending the bad one back, what a pain....

    It says that I have 2 black inks installed. I don't. It will forget every once in a while for one printing. I have tried taking the cartridges out, turning it on and off again, unplugging it and nothing seems to work now.



    frusterating!

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.

I have canon pixma mp500. The blue ink won't

This is common in Canon Pixma printers (all models). If you are refilling your cartridges or are buying refurbished cartridges this will happen more often. Take the cartridge out and put it back in. If this does not work, then replace the cartridge altogether. If that doesn't work, you need to contact Canon (us.canon.com if you are in the U.S.) for help. Let me know if this helps you.

Canon MP500 error message

If you're using Canon OEM (branded) cartridges you're going to need to ID the problem chip/cartridge so I'd try and get hold of some empty originals from somewhere (CartridgeWorld or similar perhaps?) and put those in as replacements for one cartridge at a time until you ID the problem cartridge/chip

If they're non-branded then chances are you do have more than one of the same chip but the solution is much the same...


If all else fails, take the printer to a friendly retailer who sell Canons and ask them to help you ID the problem cartridge.

Canon Pixma MP500 error

ok I figured out what to do. Open the over take out all your ink cartriages. Then flip the print head level on the left hand side up and squeeze the top of the print head (where all your ink sits on) and lift it up. You may want to blow off any dust that may be in there and put the peint head back and replace al your ink put the level down and you should be good to go if not you may have to replace the head.
