    E7 25 LSU LD DRIVER ERROR (C)

    Clean all mirrors in the LSU.
    Change the little circuit board at the LSU.

        The board is mounted on the outside of the LSU I believe. The p/n is: CPWBX2026DS53.

        Good luck,
        Dustin

          thanks for the help Dustin but that didn't work any other ideals what would cause an error code E7-25

            I would try replacing the entire LSU if it were one of my machines.

            Good luck!
