11880 for Piezography Pro


#1

If one has refillable cartridges for an 11880 that has 1 dead channel (LC, plus the cartridge is stuck, too). Could this be converted for Matte Piezography Pro printing? Second question, any advice on replacing dampers within the ink selector. Ink selector for 11880 appears not to be available from anyone, anywhere. History: capping station with pumps is 8 months old, as is the head, dampers were not replaced.
