Pixma Megatank G3270 banding lines

I am having issues with banding showing up in my printing. I have done about 10 deep cleanings, 10 regular cleanings and 2 unfortunate power clean replacing the ink in the print head to no avail. the quality of my prints are declining and i cannot get the crisp quality back no matter what i do, attached is my most recent nozzle check (which since day one I have not been able to get to be perfect at all, never really changes from the below quality) and a comparison of the great quality i had vs what i am getting now. I have had the printer since December 2025 so only a couple months old, there has been no changes in settings and no changes in materials or the program i am using to print the images. Please help 😭

Left coke can is the good quality i was getting on the left for first month of printing.

Right coke can is the banded poor quality I have been getting the past 2 weeks.

adding the below of the inside of my printer... I am almost certain this is now how it should look with the ink levels in the tubes, printer has a little over half ink for each color 😐

Hi,

Since the ink cleanings did not resolve the issue, I recommend cleaning the encoder strip inside the printer. Please click HERE for the steps.
