 Welcome to BCH Technologies. This is Kevin. Today we're going to change our printhead for T-79, which is... And the first thing you do, of course, is to shut off the electricity when this car is moving. And the next thing you do is you want to remove this cover, which is totally useless. Some people just yank it and took it out, but if you do that, you're going to leave a piece in there. I'm going to show you how to remove this piece and take the cover off. So you just get a plier and get a hold of that black plastic and just pull it towards your right. And you might get some help from the screwdriver too. Okay, so you put this piece out and the cover will come right off. This is important because later on you're going to move this piece. So some people still have this thing in it. They just rip this off with this piece in it. If you do that, then later on you'll need to remove this piece so this can be pulled out. Okay, the second step is to remove this board. I have one that is already removed. So it goes down like this. What you can see is you get a tab here and you get a tab here. And you don't need to figure out where's the tab. So because this thing is slide on a wall and you can see here this is the notch that holding the tab. So if you just slide your screwdriver, slide in and twist it like this, it'll come off. So slide in, just push the screwdriver towards the wall and just squeeze. And you'll use your thumb to lift this thing up. So this side is up, then we work on the other side. So once this whole thing is freed, don't forget to put some gloves on. If the whole thing is freed, we need to remove this piece of plastic. And just remind you again, if you still have this guy in there. If you have this guy in there, you can use your pliers to bend this, but it's likely it's going to break. Or just like me, you just pull the whole thing out. And let's see, one tab is here and one tab is here. And remember the ribbon, see there's a curve here. All the ribbons are sitting like this. So just remember this when you put it back. And now we can disconnect this. Remember for this one, the blue part is facing towards you. Now we're going to remove these screws. It's better to have a magnet, magnified screwdriver. So one's here, one's here. If you're a insecure person like me, you like to label stuff. And they give these labels. So this one is on the, so what I do is I always make the label that's towards back. And this is the chip. And we got a printhead out. So I'll say this is the printhead, printhead. And this is the bottom. That one is not the screw hole. I often get confused. It's the one here on the bottom. Now the chipboard. And often this chipboard, this assembly is really loose. So there are lots of time you put it in and this gets knocked off. And then when you turn a printer on, the printer just says there's no cartridge. If you turn the printer on and say there's no cartridge and you want to test whether it's this cable is loose or you have something going on with your chipboard. What you do is you can take your CIS out and put the original Epson cartridge in. You don't need to put all of them. You can just put one or two of them. See if the printer can recognize it. If they are, so you don't have to take the printhead out again. Focus on troubleshooting the CIS chip. And another time is I did think if I always pull and then they got disconnected and you might get a problem. So remember what we said earlier and you need to put those things in here. I know how I got disconnected. So when you put this thing in, you probably just pull on this. So get a disconnect. Just to make sure it's still good. Yeah, I still good. So now I got this piece and now we put the CIS in it. I hope you enjoyed this video. Visit us at www.bchtechnologies.com or locally at Greensboro, North Carolina. Thank you. Cheers.
