Just curious if anyone out there has Printheads for sale for Display maker 72 UVR's? Trying to avoid buying really expensive new heads for a machine so old, but I really need to replace several to get this bad boy back up to full quality again. If not, anyone have any good suggestions on unclogging, I've tried everything I could think of over the last couple years. I even drained the ink, flushed the whole system, ran head flush through the whole system, I'm just not getting them all back to where they need to be. I thought of disconnecting them, pulling them out, and soaking them in head flush, haven't tried it yet. Anyway, suggestions would be great. Thanks!
