My relatively low-mileage Epson 7900 developed the dread unclearable clog in the yellow channel (I’m pretty sure it’s a blown head, so don’t count on getting that channel back - I’ve tried quite a bit), while all 9 other channels work perfectly. I print color, so no use to me, but a PERFECT candidate for Piezography. It has printed in the past few days with the expected banding caused by the yellow, but all else works great. It’s heavy, so pickup only in Lexington, MA (about 12 miles west of Boston). BEST OFFER.
7900 Available in the Boston area (clogged yellow channel but great for conversion)
