I just bought a Continuous Ink System for my Epson 1280 printer over the internet from www.echostore.com. Well I installed it exactly like the instructions said, but the ink keeps leaking all inside of my printer. I have two 1280 printers so I tried it in the other printer, but it still keeps leaking. When I took the system out of the box I did notice that the yellow ink was not being drawn out of the tank by the fact that the tube was empty or had bubbles in it, but the yellow ink isn't the ink that is leaking. It's the Black and the Blues that are leaking all inside the printer. When I try to print something it is basically pouring ink all over the paper. I've contacted the company by sending 3 separate emails, but no response. It's been about 2 weeks now and still no response. Can someone help me fix the problem or offer any suggestions?
