Welcome to BCH Technologies. Today we're going to show you how to reveal an absent cartridge. Before we start, there are 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 hope for 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'll reveal cartridge, but cartridge still empty. So to reset that page number, you need something called resetter. And we have a video about 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 review activity may introduce air bubbles which blocks the printhead. Knowing how to unclog is very useful. There are many videos on how to unclog the printhead. We may ask 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 review tools. And there's these 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 a syringe and just use a syringe, it just asks good. Let's take a closer look at the cartridge design. On top of the ink outlet, we have something called a WON-WEE DEMPER. 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 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. See how hard it is. I just want to try some new method. There you go. There's your factory membrane. Okay, let's focus on non-violent ripples. Our goal is to add ink to the cartridge. Now, 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 use a transparent cartridge to show you the progress. In a real review, 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, you just follow our YouTube video. We're going to make a video about how to make this. It's pretty cool. Okay, you can use any size of drills. Smaller drill holes can be covered with tape or hot glue. App soon has an air vent on top, so it doesn't matter if you make it air tight or not. If you don't have a drill, you can actually use a scissor top, just use a scissor to drill through it. Maybe it doesn't matter. Just to plug in some of our products, we also sell three millimeter drills and plugs, if anybody interested. Just go to our website and the drills should be under accessories and refueled tools. And it should be on the bottom there is about 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 of ink 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 2 and flowing into chamber 1. Now we use the thumb to put some pressure on chamber 3, squeeze it, let the air come up and let the ink flow down to chamber 3. 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 solved, so you can squeeze it with any trouble. So you can add more ink if you want. And the absence cost for 12mm and it doesn't matter if you add a 10mm or 15mm. There may be concerns that the chamber 3 is not totally full. And this is okay. Let us simulate the printing process. We're going to draw ink from the outlet and simulate the printing, the printer's consuming ink. So we can see chamber 1 is the first one to get emptied. Now the chamber 2 provides ink. Okay, some chamber 2 flow to chamber 3 and the little window is to cover. And now chamber 2 is empty. And now number 3 is empty. Therefore you don't have to fill all the chambers. I hope you enjoyed this video and please check out our video about how to reset the page number so you can get a 4 ink level reading from the printer. And also follow us on YouTube channel so you can get updated when we make the unclock. That sounds bad. The unclock videos. Also visit us online at www.phtechnologies.com. We're going to have the bridge that we mentioned in Brooklyn for sale. Also we probably put a hundred dollars syringe on there too. Thank you. Bye.
