 Welcome to BCH Technologies. Today we're going to show you how to refill an Epson cartridge. Before we start, there is some homework to do. Let's start with the cartridge. The printer stores the number of pages printed on a computer chip, which is located at the front of the cartridge. Our first homework is to learn how to reset a page number back to zero. Otherwise, the printer will not recognize the new ink level. So you refill the cartridge, but the cartridge is still empty. So to reset that page number, you need something called Resetter. And we have a video of resetting the chip. You can find it on our YouTube channel. The second homework is how to unclog the printer. We might be using a new ink or even switching from a pigment to dye ink. Furthermore, the refill activity may introduce air bubbles which blocks the print head. Knowing how to unclog is very useful. There are many videos on how to unclog the print head. We may add some more later too. By the way, we have a special adapter to remove air bubbles out of cartridge. You can go to www.bchtechnologies.com and go to accessories and refill tools. And there's plastic needles. You put the adapter in front of syringe. And you push the adapter inside the cartridge and draw air out. However, if you have syringe and just use syringe, it's just as good. Let's take a closer look at the cartridge design. On top of the ink outlet, we have something called one-way damper. This damper will make the ink flow one way from the cartridge to the outlet. If you try to inject ink from the outlet into the cartridge, it will not work. One of our competitors sells a refill tool for $200. They claim that the device will let you inject ink backward. After paying the money, they will send us a 20-mil syringe. Then they tell us to push air really hard into the cartridge until the damper's membrane is fractured. So when you fracture the membrane, you can inject the ink backwards. We don't have a 20-mil syringe here, but we have a 10-mil syringe. We can offer this syringe for half the price, $100, if anybody is interested. Also, we have a bridge in Brooklyn for sale. Let's try to fracture the membrane and see how hard it is. I just want to try some new method. There you go. There's your fracture membrane. OK, let's focus on non-violent refills. Our goal is to add ink to the cartridge. Let me take the cartridge cover off first. There are three major chambers in the cartridge. When you add ink to chamber two, it will flow to chamber one. However, the cartridge needs some ink in chamber three, so the printer can detect ink from the little window underneath the cartridge. In this tutorial, we took off the cover and we also used a transparent cartridge to show you the progress. In a real refill, you don't need to take off the cover or you don't need to have a transparent cartridge. However, if anybody interested in how to make a transparent cartridge like this, and you just follow our YouTube video, we're going to make a video about how to make this, that's pretty cool. OK, you can use any size of drills. Smaller drill holes can be covered with a tape or hot glue. Epson has an air vent on top, so it doesn't matter if you make it airtight or not. If you don't have a drill, you can actually use a scissor top. Just use a scissor to drill through it. It really doesn't matter. Just to plug in some more of our product, we also sell three millimeter drills and plugs if anybody interested. Yeah, just go to our website and the drill should be under accessories and refill tools. On the bottom there is the three millimeter drill. And also the plug is under accessory plug. By the way, the green plug works better for the three millimeter drill. Now we add a 10mm vink into the cartridge. If you have a squeeze bottle kind, you can add a third of the bottle. The squeeze bottle is 30mm. And you can see the ink naturally coming from chamber two flowing into chamber one. Now we use the thumb to put some pressure on chamber three. Squeeze it, let the air come up and let the ink flow down to chamber three. So the ink can cover the window. By the way, because you're going to work this through the cover, the absence cover is very soft, so you can squeeze it without any trouble. So we can add more ink if we want. And the absence costs for 12 mils and it doesn't matter if you add 10 mil or 15, it doesn't matter. There may be concerns that chamber three is not totally full. If this is okay, let us simulate the printing process. We're going to draw ink from the outlight and simulate the printers consuming ink. So we can see chamber one is the first one to get emptied. Now the chamber two provides ink, okay? Some from chamber two flow to chamber three and the little window is to cover it and now chamber two is empty and now number three is empty. Therefore, you don't have to fill all the chambers. And I hope you enjoyed this video and please check out our video about how to reset the page number so you can get a full ink level reading from the printer. And also follow us on YouTube channel so you can get updated when we make the unclog videos. Also visit us online at www.bchtechnologies.com. We're going to have the bridge that we mentioned in Brooklyn for sale. Also, we probably put $100 syringe on there too. Thank you, bye.
