Error code U150 The following ink tank cannot be recognized

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.

The Print Head Holder moves to the center.
Caution : * Do not hold the LCD or the Operation Panel.
* Do not hold the Print Head Holder to stop or move it.
Important : If the Scanning Unit (Printer Cover) is left open for more than 10 minutes, the Printer Head Holder moves to the right side. Close and reopen the Scanning Unit (Printer Cover) to return the holder to the center.

3) OPen the Inner Cover.
Caution : Do not touch the metallic parts inside the machine.

4) Remove the ink tank whose lamp is flashing fast.
Push the tab and remove the ink tank.
Important : * Handle ink tanks carefully to avoid staining clothing or surrounding area.
* Discard empty ink tanks according to the local laws and regualtions regarding disposal of consumables.
Note : * Do not remove more than one ink tank at a time. Be sure to replace ink tanks one by one when replacing more than one ink tank.

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.
d) Remove the orange protective cap from the bottom of the ink tank.
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.

a) Insert the front end of the ink tank into the Print Head. Make sure the position of the tank matched the label.
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).
Caution : * Be sure to hold the Scanning Unit (Printer Cover) firmly using both hands, and be careful not to get your fingers caught.
* 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.

Have a good day.

Error code: U150 The following ink tank cannon be recognized (Cyan)

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!

U150 is a 'faulty electronic chip on the tank' error. If you installed a new Canon OEM tank then probably the chip on the new tank is bad.. Take that tank back for a replacement.. If you installed a Clone(non-OEM) tank, then that one will only work if you retrieve a chip from a known good OEM tank and glue it on to it. Clone(non-OEM) tanks all come without chips.
