We have had this printer for over two years. We have not used it a lot. It has started to print about five blurred lines per page. We have carried out the recommended head cleaning and nozzle check maintenance procedures several times. Epson Customer Support advised us to do this several times but the problem is still there. The cartridges are all new. We have been advised that this printer will develop head problems if not used regularly. A head cleaning kit can be purchased. It involves removing the cartridges and injecting the supplied fluid. We would like an independent comment on this problem
