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

Was pulling my hairs out when my R340 displayed the message "parts reaching end of service life, see manual". As I know these printers are not made to be "servicable", and I am not ready to pay another hundred pounds for a new printer, I was devastated. Thanks to this service program, it took away the warning message and I can continue using my R340 with the CISS. Phew!! Please note that you DO need to redirect the waste ink or replace the waste ink pads or you may risk dealing with an over-spilled printer. A wise investment into this program. Thank you.

Worked perfectly! Easy to use. Worth every penny. Saved me tons of time and money not having to bring my printer to a service center (3 hours away), and God only knows what they would have charged me. Fixed my printer in a couple minutes for about $10. Highly recommend!
