Scroll wheel doesnt work properly

Hi! I am not super well versed when it comes to mice, but I hope the following may be a bit helping.

This issue can be cause by multiple problems. A few potential causes can be:

• Dust or debris in the scroll wheel assembly. This would opening and cleaning the scroll wheel assembly. Using compressed air, a brush and/or electrical cleaner to get rid of debris and oxides.
• The scroll wheel does not make proper contact with the scroll sensor. This could potentially be fix by re-assembling the scroll wheel assembly.
• That the mouse scroll is worn out, or damaged. This would mean replacing the scroll wheel assembly.

I can not guarantee that either of these are the cause as there are a myriad of things that could cause you issue. Nor can I guarantee that either of these solutions will work.

Anyway, here is a guide on Het openen van de Logitech G305, and here is a guide on Logitech G305 Scroll Wheel Replacement. Here is an older Q&A that might prove insightful: Left Mouse Button not working consistently..

Good luck,

Cheers
