Wacom Bamboo Fun pen draws even while hovering

Question

My Wacom Bamboo Fun tablet is only a few months old and I had not used the pen when I bought it. Its mouse has been working fine. When I used the pen recently it was stuck in the drawing mode all the time, even while hovering!

What I mean by this is that the pen starts drawing as soon as it is hovering within range of the tablet! That is even when the pen is not making physical contact with the tablet. It does not matter which application I use: Paint or Paint.net, the pen always has this behaviour.

I have tried the (1) uninstall (2) reboot (3) install latest Wacom drivers routine, but it has not solved this problem. Does anyone who has faced this problem know how to fix it?

Answer 1

If your warranty is expired or you don't mind voiding it, I think I've finally found a solution to this problem.

If you take the stylus apart, you'll see the nib/pressure sensor/iron core and coil assembly at both ends of the fragile board. They're both made of six small pieces: The two large grey and tan halves of the assembly, a white Nib holder, a rubber pad, an extremely thin spacer, and some sort of magical disk thing. this assembly can be opened by gently slipping a fingernail into the small gap around the lip of the grey half, where the two meet, and carefully working the clips free. All of the small parts inside are unsecured, and will probably fall out, so try to separate the two halves slowly.

What I found is the black rubber pad starts to bend inward in the same shape as the rounded half of the Nib bracket, by just a few thousandths of an inch. This is what is triggering the pressure sensor even without a Nib in the pen.

Flip it over so the side developing a bump is now towards the white Nib holder, with the gasket between that disk shaped thing and the rubber pad. Put it all back together, and with any luck, it'll start working like new again.

When I first got the assembly apart, that magic disk was flung out. When you go to replace it, the single metal face was towards the inside of the tan mount, facing the brass contact surface. However, it doesn't seem to matter which way I put it back in, oddly enough.

There's a good walkthrough on how to disassemble the stylus at: http://wishidknownthat.blogspot.com/2009/04/fixing-wacom-bamboo-pen.html The sensor assembly is clearly visible in the eighth image down.

Hope that helps!

My guess is that the pen knows when it's meant to be drawing based on a pressure-sensitive tip. Try examining the pen and see whether it's stuck in some way. I doubt that this has anything to do with software - sounds much more like a hardware issue.

Is it still under warranty?

Answer 3

have you checked the driver settings? the pen can be configured to 'draw' when a button is pressed, maybe one of your buttons is 'stuck' i'd say try a new pen, but they are pretty expensive... unless you know someone else with one to try

Answer 4

It could be the nib in the pen is stuck in depressed (clicked) mode. The nibs are replaceable. Pull it out with a pair of tweezers or needle nose pliers (gently so you can re-use the nib) and let the pen sit on its side for a few hours, e.g. overnight, and see if it the pressure sensor will reset itself.

Answer 5

I had only had this tablet for 2 days and it started drawing while hovering! I played around with settings and buttons. And this worked me- if you click the top button on your tablet a few times (make shure you have it on Touch off after clicking), it should work.
