Hi everyone!
Jeverton, I am sorry that I did not reply to you right away. Somehow this Luminous Landscape notification with your "topic reply" got trapped in my junk mail, and I just noticed it today.
Here is my update on the Epson 7900 LLK ink clog issue: sadly, there are NO updates. Nothing, still, have resolved this ink clog problem. Nothing. And ZERO support, still, has been offered by Epson to me so far.
I have ordered a solution from American Inkjet Systems. I have, too, had a lengthy conversation with Scott there about the LLK ink clog problem. Just like you, Jeverton, I was told by Scott that it is probably an issue with the ink formula. Scott suspects that the LLK ink used as a final coat on Epson 7900 prints to give them consistent texture (I am paraphrasing here, of course) and therefore it is formulated to dry faster than the rest of inks. His explanation, even though not scientifically proven, certainly makes sense. I used his solution "as prescribed", but unfortunately, it did not clear up the clog. I do hope that the solution works for you Jeverton, if you did order it (side note: the solution, although has no odor, made me VERY nauseous, even though I left the room immediately after spraying it every time. But I tend to be very sensitive to chemicals).
In the meantime, I have been trying to communicate with Epson. (This is, to remind everyone, is AFTER I used all the common routes of contacting Epson tech support, via phone or email, multiple times).
A couple of people from this thread were nice enough - thank you, guys! - to email me privately and gave me email addresses of Epson individuals who helped them with with their Epson "out-of-warranty" printer issues in the past. So, I emailed those 2 Epson people with personal nice messages, detailing the LLK ink clog problem, and asking for any assistance. Got NO reply. NONE.
Then, searched for "Client relations" (or "customer relations") department on Epson website - which is different from "customer service." A "higher up" department, if you will. I found an email address there, and sent yet another message detailing my problem. I always mention right away that my printer is out of warranty and that is why I am emailing them (and not tech support). A lady replied to me, I got very hopeful. She asked me for additional info, such as a copy of my printer purchase invoice, and to tell her which departments I have contacted in the past. I provided all of that. Then she replies with: "Sorry, I have discussed this with our pro imaging manager, and since your issue began after your printer warranty had expired, we cannot assist you." Are you KIDDING me?
Mind you, I am not even asking for any free service from Epson (even though, this is obviously a DEFECT!). All I want them to do is communicate with Decision One, and provide me with a knowledgeable technician. I want to have a CLEAR idea of how much this will cost me, instead of less-than-qualified tech guy coming over and playing - as one of you said - a guessing game at my expense! Perhaps give me a fixed rate repair option, instead of $175/hr at "no one knows how many" hours, and "no one knows how many" parts.
I guess this is to be continued. If I have any "break troughs" with Epson, I will be sure to post an update here. I am extremely disappointed with Epson customer service (or lack thereof), and with their plain refusal to even acknowledge this 7900 and 9900 LLK Ink Clog DEFECT!
Jeverton, perhaps you should too, contact their Customer Relations department. Even though my results were negative, you might have a different outcome.
As for "raising our voices and documenting the issues" - I'm game. This is just ridiculous.
