APPLE introduced troubleshooting on their website. However it didn't work for my Mighty Mouse, also I've hardly heard of reputation that is effective for fixing the problem.
Many people dismantled Mighty Mouse to solve this problem, however it's difficult to accept for me because dismantling will spoil the beauty of Apple product.
So, I would like to introduce the way to repair Apple Mighty Mouse without dismantling. I am confident this method will be helpful for all Mighty Mouse users around the globe who are in trouble with scroll trouble because many Japanese Mac users supported it by successful comments after introducing this on the Internet 1year ago. Please try this way if you are in trouble with dust problem of Mighty Mouse.
*** DISCLAIMER *** Please try this method by your responsibility.
Double-stick tape is only material that you need to prepare for this maintenance method.
Since flexible material is better than hard one, paper based tape was used in case of this.
Tape were cut with approx. 2cm (1inch) length in this photo. however, I recommend you to cut 4-5cm (1.5-2inch) if you didn't get used to this way.
Insert small strip into the gap between mouse shell and scroll ball.
Then remove the strip after confirming this situation.
Peel back-paper of the tape.
Be careful, you should not touch surface of tape in order to prevent from deterioration of viscosity.
Stick end of the tape on surface of scroll ball and rotate scroll ball little by little. Send tape strip into inside of the Mighty Mouse.
Keep tension when you rotate scroll ball in order to prevent curling up the tape.
Keep flat the tape and wrap up scroll ball with double face tape.
Keep pushing down scroll ball with your nail. Don't rotate scroll ball when scroll ball is staying original position.
Remove oil and dust from surface of scroll ball before maintenance in order to make easy to stick the tape on scroll ball.
Viscosity of double-stick tape removes out small dust staying inside of the mouse. Scroll function will be back perfectly!! :-)
Please repeat again above maintenance if your Mighty Mouse could not recover scroll function or if you feel rough feeling with scroll ball.
I tried to throw away my Mighty Mouse... again and again... when I got scroll trouble. However I was released from annoyance after I found this cleaning method.
