|RE:Pen heats up, a fix? (modified 0 times) ||Scoth|
|Mine did this occasionally, I mostly avoided it by not tightening the cap all the way. It makes enough contact to work pretty early, so you should be okay.|
My thought is this is due to some paint flaking off somewhere that shouldn't, or perhaps a contact getting bent. Cleaning would be a good bet, otherwise you may be stuck buying a new pen. Definitely don't want to let it sit heating too long, shorted out batteries can be a Bad Thing.
