Espson in tank problems

Where can I go to speak to someone at Epson regarding my Epson ink tank printers?

I have had a few printers in the last 6 years. I started with a L120 ink tank and then A120 for sublimation.

I got a L3150 Epson ink eventually the blue no longer printed (never had to refill the ink when this happened) I took it to get looked at and it would have cost more than getting a new printer. I got the L3250 worked very well, was very happy and currently I have a similar problem, the blue line is missing in doing a nozzel check. I have done numerous nozel checks and head cleaning and everything ells with no luck and of cause now the ink pad is also full so there goes that one. I had a L4150 in between that I got second hand for sublimation but because you cant get the correct ICC profile for that I bought another L3250 for sublimation and converted the L4150 to normal ink again but then the ink pad was full and I had to send the printer in to get that changed with the reset code. When I got it back I have the same problem as above the blue has missing parts on the nozzel check lines but I can make that my own fault as I used off the market ink and not original (When I bought it it was advertised as original but came here in after market boxes - I should have known on the price) So I use it on my day to day printing where the lines on the pages doesn't really matter, but would have been great to have working printer after all that money was spend on repacing the pad and code).

At this time I was about in tears as I really can't constantly have the same issue and keep on having to buy new prints and end up with the same issue and there is no resolution to it.

I loved the borderless printing on the 4150 so I got the upgrade L4250 which is more than double in cost of the 3250/3251 I would normally get. But thought it will be better in quality

Now my problem with this printer is I constantly have to do a nozzel check and nozzel cleaning. I almost print every day on it and I have to do the nozzel check otherwise I have lines missing on either black or magenta. After doing the nozzel check I ink spots of all the colors on a few pages then it will be fine but I have to reprint them. My major issue is it will make the ink pad full again very quickly having to do it every day and more than once depending on how much I am printing. Suddenly the black or magenta lines will be missing and there is lines all over my pages and really its so frustrating. Especially on how much this printer cost.

and if that was the only problem then maybe I can get over it but gosh I just printed 31 pages and I can only use 18 of them as there is ink marks on the corners of the pages and a few it looks like a black skid mark on the paper.

Please let me know who I can talk to too find out if there is trick. or extra info or something I can do to not have this problem and/or how to resolve it.
