I am disposing of my Epson 7900 which failed several years ago because of the dreaded and well documented permanent Y/LLK nozzle clogs. I understand that it may be possible to install Piezography and re-assign the existing ink channels. The printer has not been used for several years and I do not know if in fact it will work. It saw very little use when it was working.
It's free for the asking but must be picked up in Northern New Jersey.
