Make sure to use genuine Canon ink cartidges.

1) Unplug the power to the printer. Remove the USB printer cable.
2) Lift open the top cover by depressing the round button on the right side of the printer; exposing the printer ink cartridges.
3)Lift the grey lever on top of the cartridges. This dis-engages the printhead electrical connections. Remove all the 4 ink cartridges from the printhead. From the cradle hold the printhead from the top and lift the printhead by tilting it toward you. Make sure not to touch the electrical contacts in the back printhead.
4) Take a small plastic bowl and fill it with 1/4 inch or less with Rubbing Alcohol(70% Isopropyl Alcohol). Dip the bottom of the printhead in the alcohol. Soak printhead in the alcohol and shake it lightly so the dried ink clogging the printhead can come loose. Us paper towels to soak excess alcohol from the bottom of the printhead. Make sure not to damage the printheads.
5) Pour some alcohol from the top of the each inlet of the ink cartridge seat and again soak up any excess alcohol with paper towel. Let the print head dry up little.
6) Put the printhead back in the cradle and insert back the ink cartridges in their right seat. Lower the grey lever back into its position so the electrical contacts are made on the printhead.
7) Plug the power and USB port.
8) Print a picture or diagram with color in draft mode. You might have to do this couple of times, so that the inks starts flowing from the ink cartridge through the print head. Then print the same in high quality. If the heads are unclogged your printer should work as new.

The Print head is sitting in a cradle. So do not confuse the cradle with actual print head. The cradle is the one that slides left and right on the metallic rod. Do NOT try to remove the cradle.
