I am setting up an Epson Stylus Pro 7800. I purchased a Piezography-Pro kit, which has 9 carts. The 7800 only uses 8 carts. I have identified 7 carts properly, but the instructions are not clear as to the use of the MBK or the PBK carts.
If I had to guess, my thought is that I could use either cart in the Black-Position. Not wanting to waste ink by loading it into a potentially wrong cart, I’m not trusting my instinct.
Which of these two carts should I use?
