  Just wanted to say thank you for a most helpful product which does exactly what it says. Followed all instructions, replaced waste ink pads and we have a working printer again. For very little outlay. Congratulations on running an excellent business. Have a good day,

  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.

  Great, for me absolutely great and excellent ! At my first email contact with 2manuals.com I received a fast response to a question about my printer and then I've been spend ~20 $ for the RX420 Printer manual and one RESET- Key , and it works :-) The Printer manual even is absolutely recommend for Technic freaks , escpecially the pictures in the 'disassembly/assembly' --_ section 4.3.10 Waste Ink Pads are useful. Many thanks and regards, Gerd

  The Epson Artisan 800FW Adjustment Program works great. Once downloaded it took me less than a minute to reset the printer. This is a very intuitive and easy to use software. I am a happy camper now. Thanks again

  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
