Awesome directions on install process. Printer USB cable is NEEDED to complete counter reset.

These Gubffon waste ink pad replacement tanks are amazing. The company has gone above and beyond with the written directions, right down to the counter reset online instructions, they are easy to follow, plain text with clearly defined photographic images.
Tank install literally took about five minutes, counter reset took a bit longer, but as my computer decided to do updates, typical, so I am unsure of the exact timing.
Once installation was completed, I needed to do printer maintenance, but mainly due to my printer having not been used in quite a while. My Epsom 2720 is running like new.
Would highly recommend this product.

Trouble with Website Info
Number of Items: 2
Their ad is misleading. There are not '2 Reset Keys' included in the package. Had some communication problems with GUBFFON but once I learned that you do not need sperate Reset Keys on a Epson ET-2800, the program download they sent allows you to reset your counter for the Waste Ink and everything is fine after that. It solved the problem I was having and they were generous with their follow up. Kodo's to them for their work in China. The Waste Ink Pad replacement is working fine.

Compre el remplazo de almohadillas para mi epson 2800 un poco preocupada por si necesitaba un código para que mi impresora eliminará el horror F11 . Resulta que no la necesita ese modelo, solo fue cambiar de almohadillas y listo . Trabaja fenomenal

Good replacement for the pads in our waste ink tank. Saves a boat load of money as compared to buying an entirely new one.
