Pixma tr4722 printing blurry lines/double words

[SarahPotts_2639]

I bought this printer used and I can't seem to get it to print documents clearly. The words are either blurry and/or doubling. I tried the print head alignment and all other maintenance tests and still no good. Please can someone help me with this asap because I need to be able to print out documents for my daughters school for this upcoming school year so I really need some assistance with this. Thank you

Hi, 

Based on the picture, I recommend cleaning the encoder strip inside the printer. Please click HERE for more information and steps on how to perform this cleaning.

Yes I see a smudge on there it's just taking a little while to get it off. I keep going back to it over and over and over again with glass cleaner and rubbing alcohol on a q tip.
