How to disable print head using K7 with Piezography Pro V2 on 9880?

Piezography Professional Tools
1

Hello,

I am just setting up Piezography Pro V2 to use with my 9880 and K7 inks. When using Studio Print, I could disable the light light black ink position, which is filled with flushing fluid. How do I disable the that position when setting up Piezography Pro V2?

Thanks, Drew Harty
