I have an Epson 7900, which I’ve owned for many years that has the Cyan channel clogged. Vivid Magenta not doing too well either. I’m sure this would be a good unit for Piezography conversion. I’m just not up to the task at this point. So, if you’re in the Chicago area and would like to take this off my hands, let me know. I’ve got the cartridges and some ink for someone who wants to invest the time.
