 Hi, this is Kevin. Today we talk about Epson's building print-have-cleaning function. Many of you cannot get the printer to print after receiving it, or maybe you were using it for a while and then someday you just find the color is missing. You run the printer's self-cleaning function again and again and just cannot get it work. We're going to use this brand new printer as an example, so let's check a couple things first. First we check the ink supply, make sure the small plugs are unplugged. This should be plugged only if you're doing shipping, but in the normal use you should unplug it. And if you look underneath the tanks, you can see tubes, make sure there's no kinks in the tube, especially the yellow color. The reason I'm saying yellow is, if this is at a really weird angle, when you're close, I'll create a kink. You can just use your finger to change it directly a little bit, so you don't have to make sure you don't have kinks. All those, I make sure there's no kinks on the tube. And for the black, make sure the black is not bending because the black have the sharpest curve to go in. Each one has a large tube on the bottom which goes to print that, and each one has a small tube from the printer. You can see each box has an air on the top. That air is the direction of the ink flow. So the ink will flow from the tank, which is a smaller tube to the larger tube. So if your larger tube is bent like this, and then you have to readjust it and make it get corrupted. You can see the large tube is full of air. This is especially true after the shipping. We should have printer dumps out of the ink during the shipment. So our next goal is to fill those empty tubes with ink. We're going to use Epson's building functions to clean the printhead. The printhead function has three methods. One is going to shake the printhead. Second one is going to use a rubber wiper to wipe the printhead. Here's the rubber wiper. I just go back and forth to wipe the bottom of the printhead clean. Neither of those two functions are relevant to us. What we need is a third function. The third function is using this rubber little chamber to suck ink out of the printhead. Unfortunately Epson not always runs the third function. So you probably will do a lot of cleanings to get a good nozzle check. So we get this new printer here. Let's say how many cleanings we can trigger ink sucking that we can fill those white tubes with ink, and how many cleanings until we can get a real good nozzle check. Set up. Maintenance. Printhead cleaning. Proceed all colors. Go for first one. It's shaking the printhead, and now it's wiping the printhead. You can see the first cleaning only did the first two functions. It did not suck ink, so those tubes still empty. Now let's do the second one. Still not sucking. Okay, finally get some colors. You can see the printer not always runs the sucking function when they do the cleaning. So you have to cross your fingers hope it does it. You can see there's still some air bubbles in the tube. So probably we're not going to get a good nozzle check. Remember the air bubbles in the magenta color? So now you can see that the magenta still need sucking. You thought it's going to be easy, didn't you? Actually I didn't do any sucking this time either. I just left the magenta box just to make sure that the ink flow direction is correct. I did not install the backwards. So you can see the flow from the smaller tube, so larger tube. So I put it back. Just keep it clean. Almost there. Guys, it takes about eight cleansings. I'm going to clean one more. This is when it seems you're making things worse. Don't worry, just keep going. Okay, 11 times is a charm. Perfect. So the next thing you'll do is just keep printing a page every day and at least print a page every day. So just maintain this printer and you shouldn't be doing so much cleaning. Okay, now it's time to enjoy. I hope you enjoyed this video. Visit us at www.bchtechnologies.com or locally at Greensboro, North Carolina. Cheers!
