PIXMA TR8620a How do you fix printer streaks/lines?

[cxiong23]

I've had a problem with the Canon TR8620a printing streaks. This printer is mainly used for a photography class. It is more noticeable on B/W, while the color not so much unless you really pay attention the details. We dont have this printer connected to wifi or anything. Only USB. 

I tried cleaning, nozzle check, print head alignment, and roller cleaning. Watched a video and did some searches. I am not sure I have enough ink for Deep cleaning but I can look into doing that too. I also took some pictures with the ink cartridges taken out. 

Any help would be appreciated. Thanks!
