Step 1: If you are in AUTO CAPTURE, you must click on the STOP CAPTURE button first (located on the far left of the TAKE EXAM screen) before retaking an image, skipping a tile, or unplugging a sensor.
Step 2: To RETAKE an image, left click on the image you want to retake and then select the Retake button.
Step 3: Capture retake, and then double left click on the retake image to minimize it. Once the image is minimized, the retake image will stack itself on top of the previous image.
Step 4: Select the tile you want to continue capturing on and hit Auto Capture to finish series.
NOTE: You will not be able to archive images until you save the exam, edit that exam, and then archive the image.
