How to Clean a Clogged Canon Printhead

A clogged Canon printhead can produce disappointing results on your printed pages. The ink can be smeared, the pages could get dirty from ink being deposited in the non-printed areas of the page, and segments of the text characters can be light or missing altogether. But before you throw out the printer or spend money replacing the printhead, try some simple steps for cleaning the printhead.
