Ok, a better scan attached.
The Pro 10s is printing beautifully apart from heavy magenta areas, proving that the right Octoinkjet in the Canon original cartridges is correct. I spent 43 years in the Litho printing industry, so I am used to dealing with ink etc.
It's just the Magenta!
Thank...
I keep getting this banding on Magenta areas, the attached is a 16bit Tiff file. The printer has had medium use with a new printhead fitted about 2 years ago. The other colours are fine.
Thanking you in advance.

UPDATE!
Apologies for the late update, but I have had a terrible time with the French cartridge supply company. After 2 failed deliveries they have now reimbursed my money!
Anyway, the problem has gone! The Pro 10s is printing beautifully. I know not why?
I will update if the banding returns...
