This printer is only 2 years old and worked fine until after xmas when it started leaking black ink badly. We had the pump cap assembly unit replaced as they thought it was that but it still seemed to leak and now it won't recognise most of the ink cartridges. We tried putting the originals in and it won't recognise them either. Has anyone had similar problems to this before with Epson printers? Its a large format one. We've got some new chips on the way but not sure if it will fix it.
