Roland VG-540i

We have a Roland VG-540i that was throwing the error code 0380. I found out it was the damper sensor and swapped it with another one. The problem moved so it is the sensor. My problem now is that I can't find the part number to order one. Does anyone have this part number or a part manual I can get? Thank you for your help!

 

I do understand the importance of the dealer as we sell and service many different types of equipment. Sometimes when the end-user has an easy fix, which was us in this case, does not always have time to wait for the problem to be rectified by the dealer, let production come to a halt, also have demanding customers who are unhappy. If anyone has this problem and would like to have the part number call your dealer at 1000006689 thank you!
