  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.

  Hi John, I just want to thank you so much for the reset key and software.  I paid you $9.99 to get those lights to stop flashing and it the software worked in a matter of minutes!  I really appreciate your service, without it I would have to buy a new printer (which I don't want to do right now!). Thank you again, you provide a great service. Cheryl

  At first I thought I was going to have to spend a lot of money and have to spend a lot of time fixing my issue. It was actually the complete opposite, it was very cheap/affordable and super easy to do. They give you all the steps and explain everything very clearly. do not waste your time with dealing with Epson. This was definitely the best decision to make. Will be back when I need to reset my printer again! Thank you 2manuals.com!!!!! To bad there isnt an AMAZING rating!!
