| That's a peak level detection error. If the scanner lamp is coming on, make sure the lamp is moving under the white refrence plate under the glass. If it is not that is your problem, if it is it could be Lens, CCD, SLG board. First make sure the scanner is moving to read that plate and lighting up though. If not, it could be a problem with the mechanics of the scanner mechanism (motor, cables, pulleys, etc...) |
