PIXMA MG6620 Black Ink Prints Blurry

Recently our printer has started printing blurry on black only printing. Either in the copy or actual printing functions. We have done all of the set up tasks, cleaning nozzles, print head alignment and the rest. I also cleaned the timing strip per another post I found and did a hard reset. I am including a few picture of the different test pages to show what it is doing, basically curving black lines to make thing blurry. Please advise this has been a great printer up until now.

update 1/4/23

I have replaced all ink cartridges, updated firmware, done deep cleaning, auto head alignments, cleaned rollers, back plate cleaning, used a q-tip with rubbing alcohol to clean timing strip and nothing has improved. I printed a page of text so that the issue can be seen clearly and am at a loss of what to try next (see photo). Is this unit dead? Do I have any options?
