Hi, Had J31 from all trays,tested sensors in maintenance and was working ok then a co worker noticed a whining sound (so I told the customer to shut up as we were trying to listen to the m/c LOL 
) anyway we found the transfer belt seized. hope this is of use.
Merry Christmas and a Hapy New Year to you all.
