I have the same problem two lines fairly clear and three/four lines double. Print on matt photo paper works - but slow- presumably forcing printer to avoid main black ink tank and print head. So maybe large print head needs cleaning although Canon say it needs to be sent to a service centre- cost more than printer is worth. Don't think Canon ar being very honest.

As far as I can tell, Canon hasn't made any information available to consumers re. how to clean the print head. I had problems with the print head on one unit and ended up simply replacing the printer.

I have a similar problem. Mine is a Pixma MX 925 (sold in the UK) Is that similar? Mine prints 2 lines nicely and crisply then 2 lines of a broader font then back to the crisp print. And selecting glossy photo paper fixes it. But it is very unsatisfactory. Surely if it alternates every 2 lines it must be a software problem rather than a blocked printing nozzle?
What make shall I get next time?

I have a Canon mx922 and when I print, from word or openoffice, it works fine. When I photocopy, it comes out with some clear lines and some that are blurred or "shadowed". I had recently "manually" cleaned the printhead and have new ink. Any ideas?

I cleaned the printhead by running water through it, as per an earlier post in this thread. At first, I thought it helped but then realized alternate lines were still fuzzy.
Print heads are quite expensive but then I saw numerous online and local stores selling new MX922's for only $66 so I bought a new one. Problem solved!
