You should have a service technician take a look at your copier. SC302 is a charge roller current error, and it could be caused by a number of things, from a dirty charge roller to a faulty high voltage supply board.

In the meantime, try turning the machine off, unplugging it, and then plugging it back in and turning it on the see if the error message will clear.
