DETAILS OF MODIFICATION
When the screws which fix the exposure lamp wings are caught at the edge at the exposure glass, SC22 turns on.
To prevent this, the gap between the exposure glass and the first scanner has been widen by modifying the wings.
Also, the left scale bracket has been modified to minimize the warp.
