I have an Epson PX710w it is a brilliant printer, happy was I...but then.... the now infamous \"end of life\" message appeared. After hours of research I found that Epson had a free download to reset and service printer, I downloaded only to find it did not work. On contacting epsonuk I was told that there is no reset utility or program for uk Epson printers and that I must take it to my local Epson service centre.... this would cost £80 plus vat and parts! more than a new printer. After advice from forums and many ebay offers of a \"genuine\" reset utility/key, I found 2manuals.com. through them I \"chatted\" with John who assured me it would work, despite Epson uk advice, and so proceeded to purchase. from start to finish it took less than ten minutes and I now have a fully working printer for a Meer $10 (about £8) I cannot recommend this company any higher ..... thank you very much 2manuals and John and one up on big greedy corporation\'s.

All I can say is THANK YOU!! Thank you for allowing me to roll back (downgrade) my Epson XP-410 printer\'s firmware with ease!! A couple of clicks, and I was downgraded. This allowed me to use non-oem cartridges that would not work no matter what I tried with current firmware (Epson updated firmware just to battle the use of non-oem cartridges). The money spent will be saved with the very first refill of these refillable cartridges I bought. I was skeptical, but it really was THAT easy! Winning the battle against Epson!! First time I\'ve ever paid for a \"hack\", well worth it!
