This happened to my Epson C42, when I rang Epson it was explained that it had reached the end of it's life and was probably the fact that the pad under the ink cartridge cleaner was full. I had been refilling my cartridges in an effort to save money but they had been leaking slightly so it cost me a new printer. I stripped the old printer down and could see no way of replacing the pad or re-programming the printer memory. So it looks like you will have to buy a new one.
