Fred, does there have to be (2) two different unclog printing and two different scheduling. I am not familiar with this is partially why I am asking.. OR, is the OP asking how to schedule BOTH the Matte and the Photo (together) or at the same time.
Yes, Vern, two separate Unclog jobs.... BUT, if you don't want to waste ink by unclogging twice, simply uncheck all the colors except the BLACK and GRAY check. See attached.
So you can run one unclog full (all check marks), and change to the other black and run unclog with colors unchecked.
I hope I answered what you were asking.
Old Fred
