 Welcome to BCH Technologies. Today is the first part of our attempt to refill the cartridge 802. And we're going to talk about, today we're going to talk about why their cartridges, like 202, 220, 228, 288, 401, and did I say 288? Those cartridges cannot be reset. OK. The first thing I'll talk about is what is residing. So after you refill the cartridge, what you want to see is you want to see your ink level look like this. They all fall. Contrary to most people's beliefs, there's no little guy living inside the printer can tell you how much ink in the printer. Or neither absent doesn't have a mechanism to tell actually the cartridge the full or not. They don't have a mini scale or something. So instead, each cartridge has a chip. And at the end of the printing, Epson is going to write how many pages printed. To be precise, they write how many times are nozzle to be fired for each color. Just make it easy, just like they record how many pages printed by this. So page 0, that means a new cartridge. Page 0, and you're going to see this. So let's assume a cartridge can print 1,000 pages. So you put the cartridge in, and the chip says 500. So Epson will say, OK, 500. That means the cartridge is half full, because supposedly it can print 1,000. So when the number is 800, Epson going to show you low ink level. So it just gave you a warning. Nothing hard, just soft warning. Just say, hey, your cartridge is low on ink, and do you consider buying a cartridge? However, if your cartridge chip shows 1,000, that means it's depleted. And Epson is going to show you a right cross on the depleted cartridge. So I hope that's easy. So basically, Epson just read a page number. If you can set up page number to 0, and Epson will be happy to accept it as a full cartridge. Traditionally, there are two ways of resetting the chip. First one is I call it active reset, which is you use a resetter. So the resetter just forced to write page 0 to this chip. And it only works if you have at least 80% of ink left. So you can reset any time you want. So for example, if you get a half tank, you just take the cartridge out and put it on this little machine with a pin. You can see it's blinking right first. Then after a successfully read page equals 0, and it turns green. Now if you put this cartridge back to the printer, and it will show a full tank. However, if you print lots of pages or they get warnings, your chance of reset decrease dramatically. For example, this one is starting showing the warnings. So if I put it on this, you can see it's keeping right. So it cannot be reset. So they think you have to throw it away. So oh, by the way, if you have this, that means there's no way you can reset it. So basically, this is active reset. You take it out any time you want and you reset it. Any time you want, I mean, before you get a warning or a depletion sign, OK? The second kind of reset is called ERC auto reset chips. If you buy a BCH refillable cartridge with ERC chips, and you can see this kind of chip. So those chip has a rolling number. It rolls from 0 to the maximum. Then it rolls back to 0 again. So just contrary to the resetter, this one, you cannot reset actively. You cannot reset any time you want. You have to let the number rolls from full tank to half tank to almost depletion. Then the computer going to show you a warning, low ink warning. Just ignore it until you come to this stage. And then you'll take the cartridge out, fill it up, and put it back. And it's going to be full again. So we have lots of cards from customer where they bought this, they put the ink in. And then when they say warnings, they take the cartridge out, refuel it, put it back, it's still in the warning, and it's still showing low ink. Why? It's because the number didn't reach the maximum, didn't roll back yet. So I think it's an infinite loop. It just rolls from 0 to max, then back to 0 again. So for this kind, you have to wait until you complete it, deplete it. And we were happy for a couple of years. And then Apson have this new kind of chip coming out. Not only has a page number and also has a serial number per cartridge. And also they encrypt it. So instead of saying serial equals 1, 2, 3, 4, and page equals 0, they encrypt the whole string like this. So there are two things significant. One is we cannot understand it anymore. If we cannot understand it, then we cannot change it. Secondly, even if we can understand it, it has a serial number. Let's say this cartridge, serial number is 1, 2, 3, 4, this page is 0. Then you keep printing. And then when you take out the cartridge, the cartridge 1, 2, 3, 4 has page 1,000. Then you reset back to 0. And then you say, OK, I will force page to 0. But then the cartridge will say, OK, 1, 2, 3, 4, I has a maximum page number of 1,000. So there's no way this cartridge can have a page 0 again. So it will still show you the maximum number. This is why you cannot reset the new card. So if you can see this is 228. This one has a serial number. And this one doesn't have serial number. So the one with serial number and the one without their look exactly the same. Then you may have question why there's a third party, they call it remanufactured cartridge on the market. For example, 220 has a serial number. So if you say you cannot crack it, why you can find those kind of third party cartridge? You know immediately this is not absent chip. So why those still exist? So what those people do is they do like this. So they have a new absent 220. Let's say this is the encrypted string. So they record this new cartridge. Then record this new serial number. They put down this one. So now there are two of this in the world. So if you use this one and then you replace with this one, it doesn't work because the printer still think this cartridge is this one. But you can sell this. You can make 100 copies of this and sell to 100 different people and put down 100 different printers. Of course, the large manufacturer, they don't just have one copy of this. Instead, they have a bank of 10,000 of those strings. And then they loaded it. And there's underground dealers. They deal with those encrypted strings. So you can buy, for example, 50,000 strings for such amount of money, then you can manufacture this. OK, you know BCH, we just want to get bigger and better. So how about this? So for the chip, instead of one serial number, so what we figure out is we put four sets of serial numbers in it. And then after they deployed the first one, then they jumped to the second one. Then they jumped third one. Then they jumped to fourth one. So this chip can be used four times. So when they finish this, they come through here. The printer will see this serial number. So it will not work after four sets of numbers. This idea still doesn't solve the collision problem. So for example, if this person bought a one-time use cartridge with this serial number, then they bought our product. So both that seller and us, we bought the serial number from same guy. Then you're going to get a collision here. So we'll say the maximum you can get is four sets of refills from each cartridge. Another thing to consider is, should we sell this chip with a refill per cartridge? Or we just sell the chip. So you'll put it on your own Epson. So OK, that's where it fall out. So let me take a new Epson to show you. So here's a real Epson cartridge. You can say Epson's cartridge have lots of inner chambers and the design. Those are copyrighted. So to avoid the lawsuit with Epson, third-party cartridges will have different design inside. But I do like Epson has this one-way damper that we cannot find anywhere anybody make those with one-way damper. So if you prefer use real Epson cartridge, you can just take this chip out, just get a razor blade and just dig in. There's no glue or anything. It just a cap. So then you can put this chip on. You're probably going to need to modify the Epson a little bit to make this work. So if you want, you can put a silver glue or some glue underneath. So we're debating which will we go. So we're with this or with this. Or maybe we just put a chip on the one-time cartridge, not one-time, refill per cartridge. And you'll decide what you want to do. OK. OK, today we're going to use Epson printer. Use cartridge 802. And we're going to show you the first reset of chips. We're going to use a refill per cartridge. And then we're going to mount the chip on. And then we're going to print the whole cycle. So we'll use up the first set of serial number on this. Because this guy is supposed to print 2,600 pages for the first loop, that's a lot of pages. So I think on the way we're going to test another thing is we're going to show you how to change different ink types. You probably know the Epson use a pigment ink. And the pigment ink is waterproof. And it's UV proof. It's permanent. And there are lots of good things about it. However, it is expensive. And when it prints color, it's not as nice as dye ink. And another thing is, OK, all the ink clogs. But if pigment ink clogs, it's really hard to remove the clog. Unclogging is hassle. So there are many, many people switch to dye ink. And then there are always people jumping out. Oh, you shouldn't use dye ink in a pigment printer. Or you shouldn't use a pigment ink in a dyeing printer. What I'm saying is, if you know what you're doing, you use any ink in any printer. I can use an Eco-Solvening in this if I like. So if you know how to unclogging, if you know how to maintain your printer, don't worry. So let me cover the dye ink. The dye ink is not waterproof. But it doesn't mean if you pour coffee on it, it's going to run immediately. And it's not UV proof. It's UV resistant. Here the word resistant. And it's like a resistant to Trump. I mean, you'll see how much they're resistant as. OK. Politicians say, OK. So basically, the dye ink is colored salt. OK, think of it as salt. When you put water on it, it's going to dissolve. Very, very easy to unclog. If you ever get this clogged, put water on it, and it's done. And the pigment ink, and this thing is like a liquid sand. If you get a sand condensed and clogged, it's like concrete. OK, so the difference is salt and concrete. So easy to unclog, super cheap, doing great job on the photo, and pretty good job for text. And most people cannot tell the difference. So it's your call. And to tell them apart, the dye ink, because it's salt, totally transparent. Just look at the yellow color. You're going to see the pigment ink and the dye ink. OK, so the most dangerous time is when you switch the ink type. You want to use up all the ink as much as possible, then switch to the new type. Switching in the type, the bigger chance is you get clogged, then you have to unclog it. So today, actually, what we're going to do is we're going to try to clog this printer so we can do the unclogging. And to clog it, we have given it the most severe shock. So what we're going to do is we're going to put the absolute initialized cartridge in it. So that's pigment ink. Then immediately after half of our page printed, we switch to the dye ink. So pigment to dye, OK? Then for no reason, we switch from dye ink to a BCH pigment ink. Then after a couple thousand pages or a couple hundred pages of pigment ink, we know now that pigment is not clogging now. So we switch back to BCH dye ink. We use a premium dye ink. Then we switch from dye ink back to absent pigment ink. So we covered every possibility. And we're going to do four different kinds of ink type switch. And we hope to print 500 pages for each ink type. And we really wish we can get this printer clogged. OK, this is interesting. It has a piece of paper in it. And here is Japanese word for paper. You can see it has some of the wider solution. So it keeps the print moist. And now we're ready to install cartridge. You can see it from manual. Actually, it asks you to shake the cartridge. This is the same thing across all brands. If you bought a pigment ink or you bought a pigment cartridge, you're supposed to mix them up before you put it in. And this is another good sign that if this thing got clogged, it's going to be bad. And you can see the design of absent cartridge. I really like absent cartridge. So I'm probably going to keep the cartridge. And I'm going to make a transparent cartridge out of this. Of course, if I have time, I'm going to make a video to show you how to do it. So basically, I really impress the quality of the cartridge. And after shaking it, the next thing it asks you to do is I remove this yellow tape. And underneath the yellow tape is where the air hole is. So I'll ask you to install cartridge. I'll just try this will be all unclogging too. So I'm just trying if the nozzle has a tight fit. Pretty tight. Good. Yeah, one of the good things is I might keep those. I might just mount the chip when for my personal use. I might mount those chips on those color cartridges because even if it's XL, the color cartridge is the same volume. So I want to keep the absent cartridge for me. And then I'm going to buy somebody's used 802 cartridge, real absent cartridge. Then I'm going to mount the chip on that. You can see the regular and the real XL cartridge. The volume is there's a big difference. I really want that big volume. Oh, the chip is XL chip. This little black here. OK, absent has been known for using the firmware to kill off the third-party cartridges. So most people will turn off the automatic update after they get the printer. So to be able to test if our chip is compatible with the most recent firmware, so we're going to download and install this one. So we're going to print some test tape. The absent printed a really good quality picture. So this is under part one. In part two, we're going to install four life cycle chips that can be reset four times. And also, we're going to switch the ink type into a dye ink. And then we'll show you how to switch ink types. And also, we're going to compare the print quality between the dye ink and this absent OEM pigment. I hope you enjoyed this video. Visit us at www.phtechnologies.com or local at Greensboro, Carolina. Thank you. Have a good day.
