  My XP-4100 printer has recognized the old (but new) empty cartridge, I can also refill it with a syringe. This is a good economic solution.

  I bought today the RESET KEY and I used it. My printer resuscitated immediately. Wonderful! I saved money and time! thanks, thanks. Patrizia

  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.

  I was at 94 percent and got a warning from my printer that my ink pads were close to the end of their service life. After doing some research with Epson and some other stores I got the impression they just wanted you to trade it in on a new printer. This website was linked by a few different blogs and turned out to be the best alternative to keeping a fairly decent printer for a while longer. Thank you.
