 Hey guys, Kevin here. Today, we're going to talk about how to add third-party inks into Epson EcoTank. As you can see, Epson's patent design is to split the ink intake into two sessions. One session getting ink in, another section getting air out. To make it easier for you to see, I will already take the printer apart and show you the tank. You can see the ink intake has split The ink comes in and it goes through a series of channels, then get it down the inside. Here's the air vent. It has a sponge to stop the ink backflow and also have a series chambers. So even you have the printer upside down, the ink will not flow out immediately. Okay, let's grab some tools. For the ink, we're going to use ink for printer and we're going to use refilling for Epson whole-dye ink, and we're going to use these standard four-color ink. You also need some tubing. I'll grab some from accessories tubing. Those four millimeter ID tubing or larger will work. Here's the ink. Of course, I can just drill through the divider and get in the end, but that's kind of ugly. Instead of drilling, we're going to just get a piece of tube and connect the intake with the bottle. This intake has an outside diameter of six. We don't have ID five tubes. We only have an inner diameter of four millimeter tubes. So it will be a rapid stretch. If we find ID five tubes, we're going to list it on our website. First, I'll attach a tube to the ink intake and then attach the tube to the bottle. To fit everything in the frame, I make the tube a little bit shorter, but I suggest you make it a little bit longer than this when you do it. Now you can squeeze and release, squeeze and release, and do it gently because what you're doing is you're expanding the diaphragms. So when the diaphragm collapses, it pushes the air into your ink bottle. So you're exchanging the ink and air. If you push too hard, you're going to break the diaphragm, and then you'll have an ink leakage problem. Success. Of course, I took the printer part just to show you what the internal looks like and how things work. You don't need to take the printer part. You can directly do this on your printer.
