You have an irreparable failure of your print head.
1) The vertical train tracks in the PGBK latticework is due to irreparable nozzle warping. This seems to be related most often from using aftermarket inks. But you use OEM. It still happens. A workaround is to not use the Plain Paper setting, which uses Pigment Black to print black. Use a Photo Paper setting, even with plain paper, which uses a composite Black made from the Dye-based inks.
2) There is irreparable electronic failure - horizontal fixed straight line of missing ink - in the Cyan swaths. Because of this, the above workaround will still have issues.
3) There appear to be other defects that are inconsequential regarding warranty replacement, if you still have warranty, because of the other two issues.
The solution is a new Print Head. Still, there is rare issue of an electronic failure in the Print Head propagating to the logic assay board. If so, then a new print head may have the electronic issue propagated to it from the bad logic assay board. This appears to be quite rare but has occurred. Overwhelmingly, a new Print Head will resolve all your issues.
The low page count (201 -250 pages) means this is a barely used printer, specifically the waste ink counter that keep track of how filled the waste ink pads are. When filled, the waste ink counter must be reset or the printer will not function at all.
Whatever you decide, print something every month that uses all the cartridges, even a nozzle check will do, if using OEM inks (sooner if aftermarket inks). To avoid nozzle warp then slow down the printer using queit or nighttime mode. This will slow the printing and generate less heat that is the cause for the warping. Lastly, stop print immediately if there is a loss of ink in the printed image. With Canon's, the nozzles heat up the ink and then eject it. The ink is used to cool the nozzles during this process. Heat can kill a nozzle if applied long enough. Stop printing and post here with a nozzle check and a sample previous sample of the ink loss. Nozzle checks are safe to print but nothing else until the issues is resolved.
You are welcome. Thanks for answering questions and posting the images.Thank you very much
Due to the the problems with the Dye-based inks it is unlikely a satisfactory workaround depending on your threshold for imperfection.I will try the photo paper option, I doubt that will work, but ill give it ago as you suggested.
Looks the same to me in my quick examination.I used the photo paper option and this is how turned out... its actually more consistent
