 Hey guys, it's Kevin. Let's fix it. If you come here, you'll probably get a leakage problem. Let me guess, your white ink is clogged and you say I'll unclog it later and this will look like later. Don't worry, it really doesn't cost you much to fix it. In a situation like this, first thing is to shut off the power and take a look. The white tank is completely gone and take a look of secondary tank and there are not much white ink left. First, we want to add some white ink. To get some white ink, you can go to bchtechnologies.com and go to DTF, Direct to Film and DTF ink. Oh, by the way, before adding the ink, make sure it gave a really good shake. Now we have plenty of ink. We can work on the printhead. First, we take the cover off. Notice the tube on the left damper, left of the white damper is empty. Right one is full. To remove them, you just leave them straight up. Most dampers can be tested with positive or negative pressure. The positive means you blow air into the damper and the ink should not backflow too much. It's not going to backflow a little bit, but it's not going to backflow too much. Or you withdraw it. You can see the ink withdraw into the damper. However, this is different from those white dampers. Those white dampers, you cannot test it this way. It is almost not a damper. It is selected to maximize the ink flow, not to preventing backflow. Let me show you how it's done by using a brand new damper. You can get a brand new damper from bchtechnologies.com and go to DTF and go to DTF parts. Make sure you select the top load, white ink damper, not those color dampers. I also add a link to the damper above. You can see for the positive test, this region should rest up. Now we're gonna test this region with a negative pressure test. For the negative pressure test, let me close the ink intake with my finger. This time don't look at damper, look at the piston. So when I release the piston and the vacuum force should suck the piston back. In practice, you don't have to have the piston suck back all the way. Let's close the ink intake with paper clip. Positive is okay and there's no negative. There must be something wrong with this region. It looks like it just fatigued on the seal. Now this damper is done, we just need a new damper. Time to test the second damper and the positive is good and the negative is good. Try again, good. You can say in real test, you don't want to draw that much air out to just risk to damage the damper. I draw a lot of air out of that new damper just to show you how it's done. Now we get over new damper replaced. You do not need a primed damper, you don't need to fill the damper with anything. Just put it in empty and you white ink management system gonna take care of it. The nipple or the stick of the ink intake should be poking out of the both of them should be poking out of that little box. If it's not, you need just a damper make sure they all out like this. The job is not done yet and we need a monitored ink inflow. Now turn the printer on and your white ink management should get to work. You can hear a bass noise and the white ink management going to put the ink in. Notice only over new damper on the left gets the ink, not the one on the right. We're gonna wait a few and see it one more time. And it's for sure the right side has some problem. The tube has a kink underneath the plastic cover. Don't do this like me adjusting the tube with the power on. However every time you shut down the power and turn it back on and the white ink management gonna work 15 minutes. So for me just save time for this video. And then we just wait a little see the result. Beautiful. Okay you just keep the white ink management system running. It's gonna be allowed for another 15-20 minutes and they usually get our printer right to print. Rest in peace those have the headphone on. Just want to have the first look of my 3D printing the cartridge for my HK416-22. You need to hear that click. Beautiful. Cog. Let's just in. First shot. Smooth. And two more shots. The guy's jammed. Let's see. Your thoughts gonna work first time right? Anyway I'm gonna keep you updated. I hope you enjoyed this video. Visit us at www.bchtechnologies.com or locally Greensboro, North Carolina. Peace.
