Great product. did the trick which always helps. I did watch your video on how you did it just incase i was doing it wrong and found that the video utility didnt look the same as the utility i used ie no Check button so was a bit unsure to start with. But the product is pretty much idiot proof.

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.
