4. Loosen and remove the 6 screws (Item 4) that hold the aluminum top plate to
the receptor support frame.
5. Lift the aluminum top plate off of the support. The AEC board, the AEC detector
board, and the image receptor detector board are mounted on the bottom of the
plate.

bottom plate.
3.4.2 AEC Detector Assembly
The AEC Detector Assembly contains the AEC Detect board and is mounted
between the slide rails on the bottom side of the IRSD top plate. If the AEC Detect
board fails, replace the AEC Detector Assembly. Access to this component requires
removal of the IRSD covers.
1. Turn power OFF. Remove the IRSD covers as per Section 3.4.1, then flip the top
plate over to access the detector board.
2. Remove the D-sub connector from the rear of the sensor assembly.
3. Loosen and remove the two screws (one on either side) that secure the shroud
(Figure 6-39, Item 1) to the front of the slide rails. Pull the shroud off the slide
rails.

from the front.
5. To install the replacement AEC Sensor board, reverse these steps.
