HI
59.A0 Error is related to ITB motor rotation error.
Following are the steps :
1)If turning the printer off and on again does not resolve the 59.00 or 59.A0 error Partially remove the ITB.
2)Turn the fly wheel on the right side to check the itb for damage and correct movement.
3)Reset the ITB and raise the green lever.
4)Use the hardware daignostic test and test for ITB motor for correct functionality.
Thanks
