I bought this printer in July and have recently changed the cartridges (definately the black I can't remember if it was also the colour ones). Since then the print has been getting gradually worse until last night there was hardly any print on the paper. The previous printer I had was an Epson CX5400 which was doing the same thing and followed the instructions on this site to fixing it and found the purge tube disconnected (the printer is still in pieces because I can't get the thing back on!). So I am now paranoid this printer has got the same problem. Any help much appreciated.
