try the power clean function ime sure you can figure out how to use this nice app
also resets the counter that epson put on all printers to shut them down when infact there nothing wrong with them they just want you to buy a new printer
also if you are using the copy ink cartridges it is recomended you buy ORIGIONAL epson inks every now and then
