 Hey guys, Kamil here. Today, you're going to solve a problem for Epson EcoTank. The scanner here, E02, and there's small number underneath 1-0-0-0-1-6. You'll find your printer start OK. And just at the random time, suddenly, you get this error. You also turn off the printer and you turn it off, turn it back on, and the error just doesn't go away. This problem may cost by a couple things. When you start a printer, the printer will try to move the scanner unit to the left and scan a small patch of white as a signal that everything works OK. The printer doesn't have eyes, so it doesn't know what's going on. It depends on a couple sensors. So the first thing you might have something physically make the scanner unit not able to move to the left, including you have a dirty cable, so there's no power to the unit, so it cannot move. Or you have something physically obstruct the pathway of the scanner and something mechanical. And the next thing is the lamp might be burned out. So if you don't see a white light, that means the lamp burned out. So it cannot scan that little patch, so the sensor will not be able to recognize you moving to the left. And thirdly, you might just have a really bad motherboard, or now it's a political correct, the main board. So for a printer this new and this clean, I don't suspect any physical obstruction of the move path of the scanner. So I'll take it out and clean the cable first. I hope you can find out just a dirty cable or misplaced cable. However, if everything doesn't work out, you can always find spare parts by go to bchtechnologies.com and then go to the printer parts and go to Epson and see if we have spare parts for you. ET2720 really easy to take apart and remove the two screws in the front and it's on both sides. Now you can lift up the whole scanner unit. There are three cables and they're in different sizes, so don't worry about mix them up. Hold them out and clean them. I'll take dry cloth, just start cleaning them. And if you use a sandpaper, use a super, super fine, like a 2000 grade sandpaper. Most most time the dry cloth just do the work. You don't need to go to the sandpaper. Another thing you can try is use the rubber eraser. To insert a cable back, it's easier to take this set pan off. So just go to a school driver or something to push the tab in and then use your hand to just jiggle it and you can take the whole cover off. Now pay attention to which direction the cable goes in. So from the smallest cable, you can see the contact points it's on the top. The medium cable contact points up at the bottom. So for the smallest cable, the shining points, the shining side should be on the top and the blue side should be on the bottom. And then for the medium cable, the blue side should be on the top. And the shining side should be on the bottom. Now we put the bigger cable, just like the two other cables on the side, and there's a sticky double-sided tape that can help us to stabilize the cables. Don't put the side cover back yet because we're going to plug in the power as it works. If it doesn't power on because your bigger cable is not installed correctly, just reinstall it. So now power it on and now you can see it can move, so the problem solved. Otherwise, you may have to take out, take the scanner and open it apart, and see all the sensors and see if there's mechanical problems. Try to use a caracopia page before you put the side panel back. So now we know the scanner is working and the only problem is it seems the nuts are clogged. Now we can put the side panel back and then insert the two screws in the front and the unit is ready for some nuts cleaning. After that is ready to go, I hope you enjoyed this video.
