Ink Associated with cyan on Epson 4900

My Cyan channel on an Epson 4900 is clogged and won’t clean. I was told to use a cart and Piezo flush for the Cyan and the the other ink associated with it. I’m not currently at the machine and was hoping that someone knew which other ink cart I should purchase to clean those two lines.


if you check the cleaning cycle, you have a choice of Cleaning Pairs it is the pair C and VM.
