  My Epson R2880 stopped printing and showed alternating ink and paper flashing lights. I had an extended warranty that I purchased with the printer but because I didn\'t register the warranty within 30 days I was told by Mack Camera that they would not honor the warranty. So after much research and web surfing I found myself at 2manuals. I wasn\'t even sure that the wic was the problem and I had serious doubts about spending more money on what could just be another scam like the extended warranty was. However like one reviewer said, what was $9.99. Well I downloaded the program, obtained the $9.99 pin code, loaded the software, and exactly as the video shows I was up and running. I couldn\'t believe it when the printer sprung to life and was ready to print. Hey, try it. You\'ll be glad you did.

  Many thanks for the reset key, Best $9.99 I've spent in a long time my dear old EPSON stylus PHOTO RX425 is all singing once again. Graham

  This was awesome. I was skeptical at first, but the program worked beautifully. Thank you for helping me, where Epson couldn\'t. I truly appreciate it! Great investment, happy camper.

  I love this service. Have purchased a WIC reset key maybe 10 times in last 7 years. Has always worked very well and saved ny printer each time. Happy UK customer.

  Hey thanks a lot! Worked perfectly on Epson SX405. Got a free reset to 90% just to check if it works and it worked great! Finished printing all needed doucments! Gonna get a key now! Thanks again!

  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

  Awesome, thank you! Used this for my Epson WF-2630 printer.

  I was very happy with the ease of ordering & installing the WIC Reset Utility Key. My printer is up and running once again after I replaced the waste toner box. THANK YOU
