I have on an old B9180 that you can't get new cartridges for.
I bought a set of 130 ml empty refillable cartridges from inkjetcarts a couple years ago, but I never used them.
All the ink colors for the B9180 can be refilled using the Z2100 130 ml cartridges.
As far as I know the printheads are ok, but hard to check on.
I am in Napa northern California and could deliver to local Bay Area.
