Hi Jeannie,
	That was us. The answer is yes, but recently the exact same problem 
cropped up again. 2 days ago a ABI FSE replaced all the sensors in the 
gripper. That seems to have fixed the problem. That being said, my 
memory was that when this happened months ago the same problem cropped 
again shortly thereafter and another service call was necessary.

Good Luck,
