    My roller ball stopped working going down????

  • Anonymous Sep 20, 2008

    My rollerball still moves down, but the phone doesn't register it moving, so nothing happens. Can still roll up and side to side, but down is a no-go, and it's like the most crucial direction.

    My rollerball/trackball and cursor aren't really responding to each other. Going up is fine.....going down is the issue. The ball rolls down, the screen doesn't register it.

Same problem, wouldn't scroll down. Lifted the ring pulled out the rollerball and cleaned it with alchohol. Used a cotton swab, soaked it pretty good and rolled it around a bit. Set it back in and it worked like new. Watch how you take it out so you can put it back in the same way.

I popped the ring off of the track ball assembly, removed the track ball unit and cleaned it with a swap and alcohol. Problem solved! Be sure you put the track ball assembly back the same way you took it out.

The only way to fully get it up and running again is physically remove andclean (with alcohol) or replace the part. If you want somebody else to do it for you, goto Blackberry Trackball. If you want to do it yourself, here is a Blackberry Repair Guide that shows how, the part is available on Ebay.

You can purchase a replacement trackball assembly for as little as $6 plus shipping.

Installation is fairly simple.

Using Brother Printer HL-2040, not so many pages printed, but have some dot in pages about 3 black dots and some fade letters. what should i do to clean drum?

Remove the cartridge and look carefully at the rubber roller. You have debris stuck on the roller that needs to be removed. Get a cotton ball and dab some rubbing alcohol on it. Then run the cotton ball back and forth over the rubber roller making sure to use a clean section of the cotton ball each time. Now advance the rubber roller and repeat with a new alcohol cotton ball. Do this until you made it all the way around the rubber roller. Allow to dry for 10 minutes and then insert the cartridge back into the machine.

The Dyson roller ball vacuum I have is making me crazy because the roller bar wont turn. What gives?

Check that you dont have anything blocked in the roller, if all is clear there is a little red button on the side off the roller. Push this in and this will reset the roller... If that doesnt work, check that it is switched on with the switch next to the power button.. That should solve your problems

Roller ball

All you have to do is take a sheet of paper with print on it. Take the battery out of you phone. Next do a figure eight motion with the ball side down on the phone about 10 times. There is something on the ink on the paper that will make this work again. good luck

Pearl roller ball

It might be a case where the track ball has some dirt or debris underneath it. First, turn the device off. Next, press down firmly on the track ball while at the same time rolling it in every direction. Hopefully that will knock loose any debris. Another tip to try is to wet your thumb with a little water and do the same thing.

If those two options don't work, you may try taking out the track ball and blowing out the slot with some compressed air. Below is a link that shows how to remove and clean the track ball:

Roller ball will not work down.

Cleaning the roller ball with a lint free cloth seems to work pretty well. Lock the hand held and then just go to town on the roller ball with the lint free cloth.
