LIVESCRIBE 3 - Ink cartridge rattles
What can I do about the rattling sound my Livescribe 3 smartpen makes?
For the Livescribe 3 smartpen there may be a rattling sound when the pen is shaken or when the ink cartridge is put to paper. This is caused by the ink cartridge moving inside the pen. It is not a defect and does not impact the smartpen's ability to track and capture handwriting.
Additionally, because the smartpen does not record audio directly (as this is done from the iOS device) the sound will not affect the quality of your audio recordings.
