At the bottom of page agree to terms and install.
On the "configuration page" and in the 1st drop down screen select your printer.
On the 2nd drop down screen is where I was getting confused as I have a
Epson Stylus Photo RX425 but couldn't see it in the listings, it is there, look for:-
"Epson Stylus CX4600(4500)/CX36x0(3500)/RX42x(430)PM-A700" and select.
Next click this page off and in the
botom right quick launch panel right click the
multi coloured printer icon.
Select the "Pretection Counter" then "Reset
Pretection Counter"
There you have it, switch off and back on the printer and all should be well.........
