My Canon MX920 printer's PGBK keeps printing blurry text why?

[Keolancer]

My Canon MX920 Printer I bought last year just randomly started printing blurry text, the last time I printed something on it was June 17 after that i haven't used it at all its been unplugged ever since I used it to print photos at a event I was working. Today has been the first time since I printed anything in a long time, I did the print roller cleaning and other cleaning options that my printer has but it still keeps printing blurry text. What do i do to fix this problem? oh and I don't know how to open this thing up and go in it at all.

Have the same issue with MX920. Some of the lines (complete) will be sharp and clear, the next two or three complete lines will be blurred or fuzzy. Kind of a ramdom thing. Tried cleaning print heads, print head alignment. 

OS is windows 10. I have two desktops, both windows 10 and both will print the same, with the blurred text lines.
