INK TANK U150 The following ink tank cannot be recognized. I have new ink in there and I did a deep cleaning yesterday.

First, make sure you have the right ink cartridges. Here are the right codes: CLI-8BK and PGI-5BK for black, Yellow - CLI-8Y, Magenta - CLI-8M, Cyan - CLI-8C.

If the ink lamp is off then an ink tank error has occurred. Try to remove the ink tank and re-seat it. Make sure you removed the plastic cover on the ink tank. If nothing helped, you need to replace the faulty ink tank.

clean the lower end the tan and install it back

5) Prepare the replacement tank.
a) Remove the new ink tank from its packaging.
b) Pull the orange tape to peel off the protective film.
c) Remove the film completely.
Important : Make sure that the protective film does not remain in the air hole. If the air hole is blocked with the remaining film, ink may leak out or may not eject properly.

Discard the cap once it is removed.
Important : * Do not touch the electrical contacts on the ink tank. Doing so can cause the machine to malfunction or become unable to print.
* Be sure to remove the clear film from the ink tank in the exact order, as failure to follow this step may cause the ink to leak and stain your clothes and hands.
* Do not squeeze the side of the ink tanks as this may cause the ink to leak out and stain your clothes and hands.
* Do not reattach the protective cap once you have removed it, Discard it according to the local laws and regulations regarding the disposal of consumables.
* Do not touch the open ink port once the protective cap is removed, as this may prevent the ink from being ejected properly.

b) Press on the "press" mark on the ink tank until the ink tank snaps firmly into place.
c) Make sure that the ink lamp lights up red.
Important : Install all the ink tanks to print. The machine cannot be used unless all the ink tanks are installed.
7) Close the Inner Cover.
Note : Make sure that the Inner Cover is closed. Printing will not start with the Inner Cover open since paper cannot be fed properly.

8) Gently close the Scanning Unit (Printer Cover).

* Do not hold the LCD or the OPeration Panel.
Note : * When you start printing after replacing the ink tank. Print Head Cleaning is performed automatically. Do not start another operation until the machine has stopped making operating noises.

Hope this helps.
Please rate my response.
Thanks
Have a good day.

your housing may be not clean try to cllean it and clean the back of the tank carfully and erinstall the tank and reset the printe4r. if not try to use the old one again and see if you get the same error

you need to reset the chip on the ink cartridge.......................

try diffrent pixma mp970 may be that defcated

Only thing you can do with the U150 error is replace the tank.

Same problem - two solutions I found helped me work out mine. One said contacts needed to be cleaned and it worked to use a Q-tip and alcohol or just click it in position several times until it recognizes the cartridge - this may work. Another said that they got it to work by installing a brand new cartridge - cool, but I have one full of ink it won't recognize. So I pulled the little circuit board off a used cartridge (like you need to do with some refills) and put it on the cartridge that it wouldn't recogrnize - works great. Still haven't figured out how to get it to acknowledge ink levels though. Canon really should be more consumer friendly since these problems seem to be intended to compel the use of proprietary cartridges.

U150 ink error fixed!

I too was getting the error for unrecognized ink cartridge. Then the little green circ board fell out of the end of the ink cartridge and it hit me that maybe if I put in the little green circ board from the old ink cartridge of the same color, then maybe the ink cartridge would be recognized. It worked! So don't throw out an ink cartridge that still has ink just because of that error and hold onto your empty cartridges in case you need the little green/gold circ boards.

This works!

I have a canon mp510 pixma same message U043 and a u150 fault.
I cant see any chip to replace and have replaced my original cartridges with a non branded cheaper type, this might be why. Does this make a difference or is this the same problem occurring with replacement canon cartridges as well.

Dont want to buy genuine ones if its not going to make any difference.

Anyone who can help me would be appreciated
