My Epson Stylus R280 is printing again! This was my favorite printer for photos and quick single-sided jobs. It printed and printed until the dreaded message and alternating flashing orange lights appeared. I was skeptical that WicReset could do anything because of the flashing lights. I downloaded the Windows version (XP), virus scanned it and after it passed, installed it. I first tried the trial reset that sets the waste counters to 90%. That worked immediately. I bought a key. That worked immediately and now my printer is working like new and waste counters are near 0. I use a continuous ink system (CIS) on my Epson printers... have for years. This software also has a nice utility to charge the cartridges and clean the heads. My R280 printer sat for a while after the counters reached limit and the ink lines filled with air. I used the WicReset utility to charge & clean, and now it prints like new. This software is easy to use and guides you step by step. I encountered no difficulties and everything worked first time. It is very good that there are smart engineers out there who took the time to reverse-engineer Epson\'s awful ink pad limitations. One note of caution, and this has nothing to do with WicReset... I print so much and fear my ink pads will truly overflow, so I\'ll be installing a waste ink tank on my printers. I had one on an ancient R200 printer and it worked great. This is an essential accessory for CIS printers. Thank you WicReset.

Worked perfectly on my Epson XP-950. The "Trial" option made it possible for me to verify that the software works as expected before I purchased a key. Having just purchased a key, I successfully reset the waste counters to zero. I also bought the new wastepads from OctoInk.co.uk. Great software which saved me a lot of money, thank you.

Just want to thank you for your service. My Epson printer is back on line again thanks to your easy to follow instructions. Sure beats taking my printer to the dealer!

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!
