Canon Pixma MG7140 – prints aren't full-color, are glitchy and often in separate "chunks"

[dreadpon]

Hello. I recently started having a problem with my Canon Pixma MG7140. Anything I print is never full-color, looks very glitchy and often isnt covering the whole page (appears in rectangular "chunks"). Here are a few examples:

I tried replacing the ink cartriges (even though they're nowhere near empty), deep cleaning nozzles, and even cleaning the inside of a printer (see the page with two horizontal folds). No dice. 

Would appreciate some pointers on what's going on with the printer 😕
