Now, this problem may be caused by a couple of things.Īt power-on, the printer will try to move the scanner to the left and scan a small patch of white as a signal that everything works okay. The printer doesn't have eyes, so it doesn't know what's going on. It depends on a couple of sensors. First thing, you may 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 and the scanner cannot move, or you have something physically obstruct the pathway of the scanner and something mechanical. The next thing is the lamp might be burnt out. If you don't see a white light, that means the bulb burnt out so it cannot scan the little patch, so the sensor will not be able to recognize you moving to the left. Thirdly, you might have a bad motherboard or, to be politically correct, he mainboard. For a printer very new and this clean, I don't suspect any physical obstruction for the movement path of the scanner. I'll take it out, and I'll clean the cable first.

I hope you can find out it's just a dirty cable or a misplaced cable. However, if everything doesn't work out, you can always find spare parts by going to and then go to the printer parts. Go to Epson and see if we have spare parts for you. ET-2720 is easy to take apart and remove the two screws in front. Now, you can lift the whole scanner unit.

There are three cables, and they're in different sizes, so don't worry about mixing them. If you use sandpaper, use a super, superfine, like a 2,000 grit sandpaper. Another thing you can try is to use the rubber eraser. To insert the cable back, it's easier to take the side panel off. Use a screwdriver or something to push the tab in and then use your hand.
