 Hi, this is Kevin from BCH Technologies. We've had many videos showing how to unclog a cartridge with a printhead. I'll put some links here. For example, we can soak the printhead in warm water or cleaning solutions to soften the dried ink. We can suck ink with a vacuum cleaner or we can suck ink with a priming clip. We can steam the cartridge to open up the nozzles. Furthermore, if we made a spongeless refillable cartridge, we can blow air from the top to push the clog out. I was bragging to my friend and I told them that I can unclog 99% of cartridges. Of course, we talk about this at the party all the time, my party. But once in a while, you're going to have some cartridges that's completely clogged. No matter what you do, it's not going to unclog. Yeah, my hobby is buy a whole bunch of cartridges. Use dry cartridges from eBay and unclog them. This video is for after trying everything before throwing the printhead or printer out. A hell-married method. Do not try this if the printer or cartridge still have some value to you. Only try it if you have nothing to lose. The integrated cartridge is an excellent choice to try this method. Because a used printhead only costs five or six dollars and will not damage the printer anyway. We made this 245, actually 246 refillable cartridge. No matter what we do, the magenta is clogged. If you don't know how to make a refillable cartridge, we have a link here that you can learn how to make them. So basically, we're going to throw this cartridge away if we cannot unclog it. Our plan is actually get a pot of boiling water and boil it. The first thing we do is we take old ink out and empty out the cartridge. We don't want to make a big mess. I was worried about the metal part going to rub against the printhead. So I put in a plastic basket. I know you like to wash this. So I'll be back a little bit later. What happened to my basket? That's not good. So we start adding ink back to the cartridge. And then we put it on a clip and prime it. We took the old cartridge out and put our boiled cartridge in. We use the printer's building function to do printhead cleaning. So the printer still recognize the cartridge. That's a good sign. Print a check pattern. So the magenta is much better than before. The boil is almost normal. However, we still can see some clogs there. So this time we're going to fill it with cleaning solution. We're going to fill the cartridge with cleaning solution and boil it a little bit longer. We use this from bchtechnologies.com and under accessories and anti-clogging agent. And we use this triple action cleaning solution. No basket this time. We're going to let it go for a little bit longer. 346. So I think that's long enough. We are 346. So I think that's long enough. We're not. We draw the cleaning solution out and then we replace it with ink. And now let's try see if this works better. Oh, thanks. Thanks for the comments. I hope you enjoyed this video.
