Have had series of 8 Epson Printers. Artisan 837 had over 12700 printed pages and 4000 4x6 photos when it gave up the ghost with \"inkpads have reached end of life\" error. I spent hours with Epson Support level 2 and they were very nice. Printer \"out of warranty\" so how about a new one. Went to Amazon and Bought Epson Expression 860. Epson support said take Artisan to Epson Authorized Repair Center....I did. They said \"it\'s out of warranty, we can\'t waste the time (or money) trying to fix it!!\" Used Epson Reset key from Epson 10 times and each time it , the error on inkpads, recurred. The Epson Utility does not do diagnosis like WIC Reset Utility!! Bottom line...Fixed my own machine for very small price and I am ECSTATIC! Thank You, Thank you and Thank you!! Very Happy in San Diego

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!

I\'ve downloaded the Epson R1800 manual. At a quick glance this is just what I need to repair/service the beast! Great service at a reasonable price - Thanks
