 Hi, welcome to BCH Technologies. Today we're going to show you how to refill the large cartridge for the large format printer and this is a T604. So most people don't know actually don't know how to properly refill it. Okay, so you're gonna have one cartridge, actually gonna have eight cartridges in this set. If you need to get cartridge on tools, you can go to BCH Technologies and go to cartridges for Epson and the refillable. And then on the cartridge model you click T604 and you can see it is the whole cartridge set with the priming tool and the resetter and eight funnels. I'm just gonna refill one and you'll have a funnel and then you're gonna have those tools. Most sellers do not include those tools. It's really helpful for you to have those tools so you don't have clogging. Of course you have some ink and you should have a resetter. Okay, what also help is you can have two kits. Okay, so the random kits from the street and that will work even better. Today's teacher's work day so I have kids with me. So first thing is let's understand the autonomy of the cartridge. So this one, you know what this one is? Is that like the entry point? Yeah, it's the word ink entry. I have a letter on it. What's that? Refill hole. Yeah, that's where the ink gonna come in and so I don't think I've got to be used over and over so make sure you got one has really strong case because you're gonna slide in slide out and so they're gonna last longer and make sure if you buy this buy with the chip. Okay and this orange cap is where they seal the air hole. Okay and you are supposed to remove it before using it and this is just a balanced air inside the cartridge. That makes sense. And this is the ink outlet where the ink coming out go to the printer. Okay so first thing you do is remove the refill hole and got your kids to hold the funnel and put the funnel in there and when you have a bottle being can make sure, okay use another hand hold this so it'll be a little bit dangerous. Okay, Ethan can do that. Good, so that's why we need two kids. Okay, one kid will not work. Yes, it's very important. Teamwork. So it's very important when you have it to try to cut this clear so it's easier to pour in and then when you pour in just make sure you pour in slowly and don't make any bubbles and also make sure only you wear the gloves. The kids don't need the gloves so when they get their hands dirty just go out and get another kid. Okay. Very loyal. Don't shake guys. Okay good. Okay clean and hold it. Don't move, don't move. Okay so if you're just sitting for a while make sure all the ink gets in and let me get it get a paper towel. Okay so now you can put a syringe on the paper towel. There you go. And can I get another piece of paper towel? Oh say it's already pretty clean. And now we need to put the refill plug back and make sure it's sealed. Okay the refill plug make sure it's sealed. Okay when you refill do not feel all the way and so leave about a quarter inch from the top. Okay so this one is designed it can hold the maximum 320 milliliters but you don't want to put all 320 and you want to put a 300 about 300 in there. Okay the next thing is if you see if you see air in here maybe it's the first time you're gonna see air so what you want to do is you'll want to use the first adapter so this adapter and you get a 10 mil syringe. You want to draw the ink out of here see the ink coming in. Good so this is very important otherwise all those ink are going to go to the printhead which possibly gonna clog the printhead. The second one is this big guy. Okay this big guy is very very interesting. Okay what you do is counterintuitive. Okay let me show you what I do. So for each liter of ink you want to put in 50 mil of air so this is about a third of liter so we're going to put a 20 mil of air in. Okay so remove this and put it aside because you're not you're gonna use this when you use the cartridge. Okay so we use this yellow adapter and put in the air hole then we put all the 20 mil in air in it. Okay actually I'm just showing this way we'll do it you're supposed to like this I see yeah and see then the cartridge is gonna push all the 20 mil back. Okay now you're gonna push all the way back again and the cartridge will push the back. You stop it exactly how much you put in. You're putting 20. Okay and this is three times 20. Okay now you can remove this and now you can this cartridge is ready for use so no air here the air is balanced. Okay so now is now when you use the ink when you're gonna reset a reset a car reset a chip when you're lowering the time to reset the chip is you have at least 15% of ink left in the ink counter in the ink gauge. Okay I'm not talking about a real ink how much physically how much ink in here so if your printer is shows low ink and where you see those color bars if it's less than 15% it's very hard to reset it you might not be able to reset it. Okay and so when you see maybe maybe 20% and you need to take the cartridge out and here's how you reset it. See the edge here and you have a you have a bar here so what you do is you have a four pins on the top three pins on the bottom so you're just line up with those pins and push in and until the light goes green when it goes green and it is reset okay and you put it in again and it's gonna show you four ink level. What happened is the printer cannot detect how much ink in the cartridge so the printer just can't how many pages printed so let's say this can print maybe five thousand copies so the page number goes from a zero to five thousand when go to five thousand the printer think you are I mean the ink has depleted and so so let's say if you are at four thousand level that's the time 20% you should reset the ink so if you take the cartridge out refill it without resetting it you put it back and this chip still shows four thousand pages so the printer still thinking you don't have ink although you have a full tank of ink okay that's why you want to reset it after you refill it okay so I think that that's all you need to know and when I store it I like to put this back so we can put it inside and so before before you use it just unplug it and put it in okay I hope you enjoyed this video and h-technologies.com and or locally at Greensboro, North Carolina you want you guys want to say bye bye
