Disklavier

Hi All,

Since I am a new disklavier owner (MX100 II), I do not know whether 
mine is broken or not. After I listened to a disk and turn the player 
off, the left pedal does not go back to the normal position. Because 
of this, I cannot use the piano as a regular piano. Do I need to do 
something to make the left pedal back to the normal position.

Thanks in advance for your help...
