Keep your cursor from jumping all over the place by cleaningyour track-ball mouse
If you use a track ball mouse this tip applies to you.
All mice are now manufactured with optical sensors instead of track balls tosense movement.
I need to clean my mouse on the inside? That's right!. If you don't know aboutthis it can cause your cursor to skip along instead of moving in a nice smootheven motion.
If you turn your mouse over you will see part of a small rubber or plastic ballthrough a cut-out in a cover. The cover holds the ball in place inside themouse.
As the ball rolls on the mouse pad surface, it causes two rollers inside themouse to turn.
One roller controls the display cursor's left to right motion. The other rollercontrols the up and down motion.
How Does it Get Dirty?
Over time the ball picks up and transfers dust, dirt and old eraser bits to therollers. If you're like me there will be a lot of eraser material all over yourdesk for the mouse to pick up!
Eventually all the dirt and debris builds up on the rollers until it forms ahard band all the way around them.
When these bands of dust and dirt get big enough, they cause the rollers toslip as the ball moves, which can make your cursor do funny things.
Cleaning your mouse is very easy to do! You can clean the mouse with the PC onor off. The cursor will jump around if you leave it on, but it won't hurtanything!
Removing the Track Ball
The ball we talked about is held in place by a circular cover that eitherslides or spins off. Take a close look at this cover. There is usually somemarking or text on it (similar to those on the battery cover on your portableCD or cassette player) that indicate which way to get the cover off.
Once you get the cover off, slowly turn the mouse over and the little ball willroll out.
Check the ball for any obvious surface damage, which could really cause strangecursor movement. If this is the case, then give this mouse to the cat and buyanother one. I've never seen this happen but it is possible, especially if the mousehas been subject to really rough treatment.
If the ball is OK, put it and the cover aside in a safe place.
Cleaning the Rollers
Now that the ball is out, look inside and you will see two large rollers (theseneed cleaning), and a smaller one, which doesn't. The small roller is there topush the ball against the other rollers. You don't have to do anything withit.
The next task is to find a small relatively hard object to clean the rollers. Atoothpick or Q-tip will work. Pretty much anything that is small, stiff and nottoo sharp. You don't want to scratch the rollers!
Begin with one of the rollers and scrape the ring of dirt off in a motion inline with the axis of the roller. As you get the dirt off in one spot, spin theroller a little and work on the next spot until you've gone all the way aroundand the ring has been completely removed.
When both rollers are clean, hold the mouse upside down and shake out all thedirt that you removed from the rollers. You may have to blow a little air inthere to get it all. Don't leave any in there, because it will soon find it'sway back to one of the rollers!
With the mouse upside down, put the ball back in. Then slide or turn the cover(depending on how it came off) back into place.
Congratulations! You are done!
Don't Forget Your Mouse Pad
Before you start using your mouse again, make sure your mouse pad is clean. Itis a good idea to clean your mouse pad often to keep dirt and erasure debrisfrom finding it's way onto the rollers.
