 Hey guys, it's Kevin. Today I'm gonna show you how to unclog the HP-910 printhead. Sorry about the noise. We work from the warehouse, so you'll either hear a forklift or truck or airplane or maybe a SpaceX gonna fly by. I probably unclogged a couple hundred of those printers so far, so this video is based on the experience I have from those printers. Those printers are usually really dry and they don't have cartridge for months. So if I can unclog this, you'll unclog yours in no problem. Okay, I just grabbed this random one and it doesn't have cartridge on it for a long, long, long time. The black isn't that bad, but all the colors, they're like a dried solid. I just put a new cartridge on it and do a test. HP has a different level of cleanings, so the first time you run the cleaning, it doesn't do much. But enough cleaning, it's gonna spit out a piece of paper and show you the result. As you can see, the black is not that bad, but it's still clogged and there's no color. All the colors, they're dry and clogged. Okay, back home, you should do more head cleanings before you buy anything. But because we know the history of this printer has been a dumpster, has been under the sun for a long while. So we know that the building cleaning is not going to solve the problem. So we go to bchtechnologies.com and go to accessories, an anti-clogging agent. We definitely need this too, the flash too. However, it's cheaper for us to go to the second page. It has the flash too with the red cleaning solution. There are three levels of cleaning solution. There are green one and there's a red one. The red one has the maximum strength and back home, if you want to use green one, that's fine. But again, this printer is heavily, heavily clogged. So today, we're going to use the combination of the red cleaning solution plus the cleaning tool. We're going to get a little container and add some cleaning solutions to it. Then we suck some solution into the syringe. For the bigger one, you only need to fill one third or a quarter of the syringe. Now we're going to take out all the cartridges. Okay, let's make a diaper for the printer. So get a paper towel, fold it in half, then fold in one third, and then now just tug it underneath the printhead. Oh yeah, I cut the power off before you do this. Your left hand should push down the tip evenly, have even pressure. If you don't have even pressure, you're going to see the juice come out all around it. This piece of black washer is a sandwich between your tip and the base. So not only you need to stop the leaking from the top, from the top, you also need to stop the leaking from the bottom. So to do this, you need to have even pressure. Now I'm going to switch to the smaller tip and do the rest of the colors. Remember, you'll go with some of those red cleaning solutions inside the printhead and leave it there. And you go with not a totally flush everything out of the system. Now the printhead is filled with cleaning solutions and we just put the cartridge back, close the cover, and then just leave it overnight or for 12 hours. 12 hours later, don't forget to take the diaper out before you plug in the power. So now the printhead is filled with cleaning solutions, but the cartridge filled with ink. We just use a printer's building function to do a cleaning that will suck out the cleaning solutions. Okay, you can see the color is back and that's not bad, but the magenta has a white strip in the middle. So we'll go to the second level of cleaning. Just click clean again. Okay, here's our first cleaning. The next two ways is over second cleaning or we call it the first cleaning after the flush. So we can see the black is unclogged, it's a little bit fuzzy because you're changing the ink types and the color is back, but I have a white strip and this is the third one. And the third one, compared to the second one, you can see that white strip is gone, but the magenta, where it didn't have a strip before, now has a strip. That's because you run out of magenta ink and this is the quickest way to add the ink to your cartridge. Now you can see the magenta is solid, but I have a little bit of stripes and at this stage do not clean anymore, do not clean the next level. Just leave it like that and leave it for a couple of hours and come back and it's going to be perfect. If you still have problems, probably you want to just repeat the whole thing one more time. And then before you throw the printer in your garbage. Oh, by the way, the black look a little bit fuzzy because I'm not using the real ink. I'm using ink combined with a wetter solution, so after I unclog it, I can sell it. So that's why the black look like a bit fuzzy. Oh, by the way, I'm going to put a link to the unclogged print ad because I'm selling those print ads. I'm not putting it on the description section, but if the link is gone, that means everything is sold. I hope you enjoyed this video.
