 Hey guys, Kevin here. Today we're going to show you how to deal with the situation that you burn your print net. If you see this error, there are three possibilities. You burn your motherboard, or you burn your print net, or you burn both. Congratulations. I got you this printer, a smoke coming out of it. Okay, here's what's left inside the printer. The problem is leaking ink. I have to take this whole thing apart and check the leaks. The ink leaked into the print net, and then the person turned the printer on. There's a short inside the printer. The first thing you want to do is check the motherboard. Normally on the motherboard, there are lots of writings looking for the letter F. Normally the F1 for the fuse, and in this case I think it's an F301. There should be only one fuse for the whole motherboard. Did you see the F301? Okay, that fuse is not for the motherboard. That fuse is for the print net. You can have the motherboard intact, but that fuse blew out. If that fuse is okay, then you start checking the transistors and then you check the capacitors. I'm going to have a separate video to show you how to test and troubleshoot those. I'll just say this motherboard is okay. It's a good one. Let me just show you another board. This is CD16, and the F1 fuse is right there. Normally if you blow out the transistor or like a MOSFET or a capacitor, the motherboard will not turn on. If you blow out the F1 fuse, the motherboard will still turn on like this case, but the print net cannot work. Okay, after we check the motherboard, now let's look at the print net. You can see there are burn marks on the flex cable. I look at the print net and we can see the pin is already burned. It's burned inside out. Once the print net is burned, there's almost no chance that you're going to be able to fix the print net anymore. If you come here and see how I fix burn print net, you're in the wrong place. Once it burned, it's burned. I can't help you too much. Go to Google and search for the word print net Jesus, and he may be able to help you out. So we're going to keep the motherboard and we're going to switch to a new print net. For the cable, you can go to bchtechnologies.com or go to printer parts and you can either go to a general flex cable or you kind of go to absence flex cable. Let me show you a way that you can reuse this cable without buying a new one. You can see this cable is burned all the way through. I'm going to peel the blue tape in the back. You don't have to do this. You can just use a piece of duct tape instead of the blue tape. Now you can see how badly the cable is burned. I'll take a pair of scissors and cut off the burn part. Now we glue the blue tape to the back of the cable. However, again, you don't have to use this blue tape. You can just use a regular duct tape to do the same thing. Now we wrap some paper around it and put on a clamp and let it dry. After it dried, I find the easiest way is to use a file to get it started. Once you see the metal is exposed and the switch to a really sharp razor blade, I start picking. To the final finish, you can use really fine sandpaper like 400 to 800 grit. There's actually two cables fused together. There should be a gap in between the two cables. So don't worry if you see a gap in the middle. Now we can install a new printhead and see if it works. Okay, ready or not. Oops. Oh, there we go. Come on. There we go. How's that? No errors. I hope you enjoyed this video. Visit us at www.bchtechnologies.com or locally at Greensboro, North Carolina.
