  Just over a week ago, I figured I was going to be in the market for a new printer. When the error message came up on my Epson XP-610 stating that "Parts inside the printer are at the end of their useful life" I initially was quite disappointed. However, after a quick Google search for that phrase, I came across the OctoInkjet website. After a little further research, I decided to give the trial waste ink counter reset code a shot - after all, what did I have to lose - and, somewhat to my surprise, it worked! Knowing that I then needed to purchase a new set of ink pads and a reset key to fully resolve my printer issues, I was pleasantly surprised at the low cost of purchasing both of these items together. I then placed my order, but knowing that the product was coming from overseas (I'm in the USA), I figured it would be a minimum of at least a few weeks before my printer pads arrived. But, lo and behold, the pads arrived on my doorstep in just over a week! I was thrilled and so I quickly replaced the pads in my printer with the new set (which, by the way, were a perfect fit and the instructions provided were excellent), ran the counter reset program applying the reset code I had purchased, and everything worked flawlessly! So now it feels like I have a brand new printer (although it's probably about 5 years old) and I can continue to purchase inexpensive third party ink cartridges (which I have always done), continuing to save me money for years to come. Thank you OctoInkjet!!! I will certainly be telling others to check out your product. P.S. - I seldom write product reviews so this shows how impressed I am with this product. I particularly love it when a solution is provided that overcomes "planned obsolescence" by the manufacturer.

  My printer stopped printing with the error as \"General Error\" Epson quoted me $60 to send an engineer to fix my printer. After reading through the information on this site I decided to fix it myself. Found the problem was related to the waste ink pad counter. Only 10 minutes, I had the the printer working. The printer tested fine and has done approx 150 pages since with NO issues. Thanks for your WIC PROGRAM!

  This is like Magic!! I decided to leave a positive review because it saved me so much time and heartache. I needed to finish a lastminute order and of course that's when my printer decided that my ink pad was full. I was panicking cuz I only had a couple hours to complete the order. I took a deep breath read and followed all the instructions from here and within five minutes my printer was printing again!! Thank you!! Will definitely come back when/if it happens again!

  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.

  Thank you so much for the reset. I was able to clean my ink pads, and then using your reset utility, reset my printer and now it works perfectly! So much better than buying a new printer!

  Whenever I try to do the ink charge, ink out appears here, so far it hasn't worked for me, could support staff be able to help?

REPLY: To use Ink Charge - ink levels must be more then 50%
