    Hai all, i need help.
    My sharp copier AR-M450 show e7-02.I change the laser motor, still show e7-02 code.

    E7 02 Content Laser trouble
    Detail BD signal from LSU is kept OFF, or ON.
    Cause The connector of LSU or the harness in LSU
    is disconnected or broken.
    The polygon motor does not rotate normally.
    The laser home position sensor in LSU is
    shifted.
    The proper voltage is not supplied to the
    power line for laser.
    Laser emitting diode trouble
    PCU PWB trouble
    Controller PWB trouble
    Check and
    remedy
    Check for disconnection of the LSU
    connector.
    Use DIAG (SIM 61-1) to check LSU
    operation.
    Check that the polygon motor rotates
    normally or not.
    Check light emission of laser emitting diode.
    Replace the LSU unit.
    Replace the PCU PWB.

    Replace the Controller PWB.

    HOPE IT WILL HELP!

    If the polygon motor wasn't working you would get an L6-10. The E7-02 means the beam detect sensor never received a beam from the laser. As the previous poster stated you'll need a new laser unit.

    Hope that helps !

    Like Tony says,
    L6-10 = mirror motor
    L7-02 = laser diode

    either way order the laser unit.

    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
