 Here you guys, this is Kevin. Does you help make the similar noise as you upstair neighbor? And then just throw an error, like 21 or EO1, that you have no idea what it is? Let's turn the printer off. Let's check inside the printer. Some model can open easily, but for this 2,800 model, you need to remove a screw on really far left, then not this one. And find another screw really far right on the top, that one. When you open it, don't raise the scanner too high. Otherwise, it is going to pull the cable out. Instead, just open it like 30 degrees and put something there to hold it. You can see this piece of clear plastic comes out. Put it back is not that straightforward, trust me. Japanese are the guys that invented this. Let me show you how it's done without torturing yourself. Pay attention to this hole. See, I can fit in this tab. Then you can slide it backwards to fix it. OK, now let's take a look at this hole. Right on top down, you can slide it in the tab, sideways, right? And then you can push the first hole top down and slide back. With those two holes in position, now we can work on the last one. Perfect. Now the only noise you hear will be your upstairs neighbors. I hope you enjoyed this video.
