I was having some print issues on my Epson 9800, Typical clogging in the black due to the type of ink I'm using.
I had this issue before when I was in California, went through a whole assortment of troubleshooting (including installing a new print head). I believe we finally solved the issue by replacing the damper. (Professionally installed by certified epson tech)
Well, a year later now, the same thing happened again. I was able to purchase a box of dampers from China, but I couldn't find any epson techs in my area (closest tech is in Portland, OR- about 4 hours away.) I found a random company online that said they could help me. The tech came and replaced ALL of the dampers, (not just the black like I asked), and now I have lost the air seal and my machine will not print ANY color at all. I really need someone who knows these machines to come help, I don't have a truck or the time to haul this large machine to another state to get fixed.
