Logitech MX Ergo Scroll Wheel (fixing slippage)

简介

If scrolling the scroll wheel starts becoming imprecise or seemingly "slow", it may be because there's filth accumulation affecting the movement sensor. Because of the rolling movement of the wheel, dust accumulates in the form of a ball and will block the photo-sensor intermittently. There's some discussion on the internet that may lead us to think that this behavior is an app configuration problem (if you're using Logitech Options), but after opening the device I confirmed that, in my case, it was just dirty. Please note that you just have to disassemble the device using the instructions you will find right here on iFixit up until step #2 of the Disassembly Guide to reach the scroll wheel, so you may skip steps #3-#11 of the guide below.

Before going to all that work, I tried using a can of air to forcefully blow into the gap on each side of the scroll wheel. I don't know if it got any lint out, but it started working perfectly again without having to disassemble it.
