How to replace printhead.
Instructions
>Press the printer's "Power" button to turn it on. Allow the printer to finish its start-up processes before continuing.
>Unfold the printer's output tray completely. Lift up the printer's cover and wait for the cartridge assembly to move to the center of the printer.
>Open the inner cover to reveal the printer's ink tanks. Remove each ink tank by pinching the tab at the front of the ink tank as you lift it out of its slot.
>Pull up on the gray lever until it cannot move back any more. Grab the black plastic print head assembly and lift it straight up and out of the printer.
>Remove the new print head from its packaging. Place it in the empty slot. Lower the gray plastic lever until you hear a click.
>Replace each ink tank, making sure you hear a click from the front tab. Close the inner and top covers on the printer.

I tried your solution twice, and it did not work.
The solution was potentially helpful, but it did not fix the problem. Even though the printhead looks OK, I guess it broke somehow. The second time I wiped a little ink off the printhead.
Also, I have always used Canon ink cartridges.
