Hey guys, it's Kevin. Today we're going to work on the absent echo tank. We get a weird problem that the customer reported that she can get the first page print perfectly and the second page will be clocked and she's going to see the stripes or a pretty much lack of ink. So the second page will be clocked. I made this video just won't show you that not all clocks need to be flashed because most people when they encounter a persistent clock immediately on their on their mind is let's get a cleaning solution let's flash the print head. What I will do is I suspect there's nothing to do with clogging so let's print a nozzle check. You can see the nozzle check is perfectly. You got a line clear and don't miss it. Don't forget to check the yellow line. The yellow line is hard to see and but if you hold at the angle and you can see a line is there so there's nothing wrong with the print head. So stop stop troubleshooting the print head. Your problem probably is the ink supply. When they check inside for this model to be open open it you have to remove the two screws on the far left and the far right. This one on the far left corner and not this one okay. There's wire on the really far right right here okay. So remove those two screws. Don't mess with a middle two screws. We'll leave the cover up. Do it slowly and only lift up this much. Let me show you why. If you leave up too high you might drop off those those three cables. I'll just use some paper towel to keep the cover open. I need this I need to move this to the middle. I can say it's locked. So what I can do is see that wheel I turn it four to six times counterclockwise. See it still cannot move. The trick is push the right turn pull it to the left. Now I could just use my finger to pull those tabs in and then now the the damper can be removed. The damper seems okay. There's about three fourth of ink inside each damper. It may be better I show you the yellow ones. See the printer should get enough ink. There are plenty of ink in the damper. Although it's kind of let it be low. It's like a half full but I don't suspect anything wrong with the damper. Again there's nothing wrong for the print head. So probably there won't be anything wrong with the damper. So we need to try. I just stuck a syringe in the cyan damper and start pulling. It's very very hard to pull anything into the syringe and this is no right. You can see I almost get a vacuum inside the syringe. Normally I should feel really smooth ink flow into the syringe. See as imagine. So when I pull I almost get a 10mm of vacuum at the same as yellow. And I'll use yellow. I work on the yellow first because it's easy to see. Just make sure the problem is not are the syringe we used. I'll take a razor blade just cut it cut it at the angle. So the final result should look like this and you can see it's really really hard to suck and ink out of the damper. So if this is your printer, A has no problem to suck off a little bit of ink. After that there will be a vacuum inside the damper and you will printer will starve starve with a ink. So I will show you clogging or I just know ink at all. Okay let's see if the problem is the tube or the damper. So if you if I remove the damper it's hard for for me to insert the syringe into the tube. I'll use a adapter. I'm going to put the link to the adapter above in case you want to have one. You can see the problem is the tube and as I draw it it's really hard and solid ink flush in. So they're kind of clogging or kink in the tube that are just fixed by draw a lot of ink out of it. And you can see the ink can flow nicely into the damper. However for the syringe tube no matter what I try I cannot unclog it just by sucking. You can see how we did it is we starve with a printhead then we troubleshoot backwards. So we test the damper and then we test the tube and later what you can do is you remove both ends of tube and make sure there's nothing blocking the tube and then you can work backwards to the tank. Oh I forgot it is when you do this make sure you lift up the refill plug first open it and then then you discharge the ink this way. And here's the picture of the tank. So you get your refill plug here and the tube you can remove the tube without taking the cover off. So the next step will be remove the tube and they can pull all air or inject something make sure the liquid coming out of the tube. It's pretty easy to unclog if the thing is inside the tube and then after that you'll pass back as there's air hole. So you get the ink coming from the refill hole. Here's where the printer keep the ink. Then on the top you can see a lot of channels and that sometimes when you move the printer the ink get into the channel then dry there. So there's no air coming in so that's where you vacuum. That's what caused the vacuum inside the tank. For this printer the customer decided to stop troubleshooting because the printer is still under warranty. So I just did quickly pack it up and give back to the customer. However I think you got the idea of how to troubleshoot this. You can see after we've done although within fixed problem the printer still print a very good not to check. So there's nothing wrong with the printer not all your clogging is from the printer. Okay I hope you enjoyed this video. Visit us at www.bchtechnologies.com or locally at Greensboro North Carolina.

My bacon supply is kinda low and also I want to try out my 3D printed magazines.
