#2 - a resetter, extra cartridges and ink - is called The Hat Trick.(1) use OEM inks and change each cart as they empty and you will get a complete purge cycle every time you do that, so 10 cart changes = ten purge cycles. That what’s known as the Domino effect and Canon will love you..
(2) Use 3rd party inks and change every cart when one cart get low or empty (Replace the lot)
Hat, I have both and can tell you the colours of the PRO-10 are deeper, even on matte papers.The Pro 10 is a nice machine, but I still love my two Pro-9500’s, 12 years on..
No problems with waste ink or resetting the ink counter..
