MPC5000 Blown Fuse

Hi,

We have a customer with a MPC5000 that has a history of blowing the fuses on the PSU.
As suggested by Ricoh, the cause is apparently the IH Inverter, which we have already changed.
Today their machine has blown the fuse again, and now we are back to square one.
Has anyone had any problems with this, and is there a permanent resolution?

Regards


Nick
