 Hey guys, it's Kevin. Today we're going to work on Epson EcoTank. We get a weird problem that the customer reported that she can get the first page print perfectly and the second page will be clogged and she's going to see the stripes or pretty much lack of ink so the second page will be clogged. I made this video just to show you that not all clogs need to be flushed because most people when they encounter a persistent clog immediately on their on their mind is let's get a cleaning solution let's flush the printhead. What I will do is I suspect there's nothing to do with clogging so let's print the nozzle check. You can see the nozzle check is perfectly. You got every line clear and don't miss 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 every line is there so there's nothing wrong with the printhead. So stop troubleshooting the printhead. Your problem probably is the ink supply. When you check inside for this model to be open the open net you have to remove the two screws on the far left and far right. This one on the far left corner and not this one okay there's one on the really far right right here okay so remove those two screws. Don't mess with the middle two screws. When you lift the cover up do it slowly and only lift up this much. Let me show you why. If you lift up too high you might jerk 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'm going to do is say that wheel I turn it four to six times counterclockwise. See it still cannot move. The trick is push to the right then pull it to the left. Now I could just use my finger to pull those tabs in and then now the damper can be removed. The damper seems okay there is 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 on the printhead. So probably there won't be anything wrong with the damper so we need 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 not right and you can see I almost get a vacuum inside the syringe. Normally I should feel really smooth ink flow into the syringe. Same as my gender so when I pull I almost get a 10 mil of vacuum. 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 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 any ink out of the damper. So if this is your printer it has no problem to suck up a little bit of ink. After that there will be a vacuum inside the damper and your printer will starve with the ink. So I will show you a clogging or just no ink at all. Okay let's say if the problem is the tube or the damper. So if I remove the damper it's hard for me to insert the syringe into the tube. I'll use an 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 suddenly the ink flush in. So they're kind of clogging or kink in the tube that are just fixed by by draw a lot of ink out of it and you can see the ink can flow nicely into the damper. However for the cyan tube no matter what I try I cannot unclog it just by sucking. You can see how we did is we start 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 is when you do this make sure you leave up the refill plug first open it and then then you'll 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 in the next step will be remove the tube and they can blow 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 your best bet is there's air hole. So you got 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 your vacuum that that's what causes 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 how to troubleshoot this. You can see after we've done although we didn't fix problem the printer still print very good nozzle check so there's nothing wrong with print head. Not all your clogging is from the print head.
