I'd say it's a 95% chance you broke one of your waste feed lines. Look in and around your capping station and see if one of your lines is broken. If you can't see anything, do a couple cleanings and watch your two small waste feed lines. If they aren't pumping ink, then you have one of your lines busted (happens all the time).
If it's under warranty, get a authorized tech out to replace the line and capping station. if it's not, then you gotta order one. If possible, ask for one from one of Mutohs full solvent printers, as their lines are apparently stronger and won't break like they will on the Mutoh eco-sols.
