Epson 9890 44 inch printer

I have an Epson 9890 44 inch printer. It works great except one nozzle is clogged and I can’t seem to get it cleared. All other nozzles are working fine. I figure someone could convert it to a piezography printer. I’m located near Ellsworth, Maine. I do need to make something off the sale, as I need to replace it with another 44 inch. Thanks!
