I was skeptical, like I'm sure we all are when buying something new online, but I simply turned off my Epson Monitor, under maintenance tab, bought the key, turned off my printer, then turned it back and and IT WORKED! Well worth $10.00, just so I don't have to buy another printer.

This is your sign that this is legitimate. Easy process and worked exactly as described.

Your Epson C42 Service Program worked a treat to clear the counter. So easy even I could do it
