PIXMA MG5750 writing not clear with weird double lines

[maeneel]

as you can see in the photo i added below, when i use my "CANON PIXMA MG5750", it prints some lines normally in a very clear dark visible way, but some other lines are lighter, less visible and in a weird double lined pattern, i tried all the cleanings available in the settings, tried manually cleaning the print head (pretty sure i did not damage it as i just wiped the ink it had on), printed so many nozzle checks i can't even count them, i don't know if it has something to do with colored ink because i don't have but my black ink is full (both the PGBK-BK), if anyone has an explanation or a solution to this please tell me because i urgently need my printer for university work, thanks to everyone and have a great day.
