No image
• Make sure that the lens cap has been removed from the camera.
• Check the camera cable harness connection at the back of the
dispensing head.
• Check the two cable connections (part of the tie-wrapped harness
connecting the computer to the camera and light ring). The 12-pin
cable connects the computer to the camera, providing power and
video feed. The 15-pin D-sub cable connects the computer to the
light ring.
Unfocused image
• Adjust the focus.
• Check to make certain that the substrate is within the height focus
limits of the system (see AV-700 specifications).
• The camera lens may have been dropped, damaged from harsh
chemicals or the environment, or has hit objects during operation.
