Canon Pixma pro 100 Ink how to identify the black cartridges when label was accidently removed

[mlevick]

I just started putting a new Canon Pixma Pro 100 printer together- I was not thinking and removed two of the grey (light), and grey cartridges labels. Now I do not know which to put in the slots, I cannot see any gradient by holding them up to the light, and the actual cartridge is not marked. I am soooo dumb, any suggestions.

I think you are out two cartridges. I have studied mine and see no difference other than the label.
