Hi! I've been printing just fine, then all of a sudden today I'm getting these marks on every single print. I've tried all the maintenance options, cleaned the print head. Seems to be coming from a roller potentially, or around that area. Just so confused as it was perfect just last night. It's the lines either side of the white line on the right side of the green

As the problem is only in green and not in red and green is made from cyan plus yellow and red is made from magenta plus yellow, I think the problem is in the cyan channel, which looks like the cartridge cannot deliver enough ink at the end of the printhead travel to the right. I suggest to try another cyan cartridge to see if that solves the problem.

Unfortunately it's made no difference. It is there for other colours - but not as noticeable

@PeterBJ is right, your cartridges are not delivering an equal steady flow of ink, and my money is on the cyan cart too..

I've replaced both and it's the same issue. It's not just showing on the Blue parts of the print, it's also there for other colours also, just more noticeable on the lighter colours. It's consistent on every print as well - exact same spot

I still think the error likely is caused by an ink flow problem from the cyan cartridge. So what kind of cartridges do you use? New OEM or ?

Sadly the sudden appearance of the error could also mean that the printhead has failed, but if you use anything other than new Canon OEM cartridges I suggest to try a new OEM cartridge.

On one of my Epson printers this happens when one of the ink nozzles blocks up. In my case it is usually one of the magenta nozzles that fails the nozzle check. That then results in a print like yours, in some printhead passes, the head fails to spray ink through a certain nozzle to the paper.

However I have a workaround using the setting 'quality enhancement'. The nozzle will use less nozzles (in my case it won't use the clogged ones) each pass. Printing will take very long with this setting as only use a small amount of nozzles of each channel are used.

Might help you to get the prints done, but I don't know if Canon provides such setting.
