Mouse scroll wheel jumping or scrolling the wrong way

The scroll test above counts steps that go the opposite way. A few reversed steps while scrolling one direction is the classic sign of a dirty or worn wheel encoder.

Langkah

  1. 1

    Blow out the wheel

    Unplug the mouse. Blow compressed air into the gaps on both sides of the wheel while rolling it.

  2. 2

    Check free-spin mode

    Some mice switch between notched and free-spinning scrolling with a button behind the wheel. Free-spin can overshoot.

  3. 3

    Adjust scroll settings

    On Windows, Settings › Bluetooth & devices › Mouse sets how many lines each notch scrolls. On a Mac, System Settings › Mouse sets scrolling speed and natural scrolling.

  4. 4

    Wireless: fresh batteries, closer receiver

    Weak batteries and distant receivers cause erratic input.

  • If cleaning doesn't help, the encoder is worn. Replacement or a warranty claim is the reliable fix.
