Summary:A scanner and process for detecting a scan lid open condition. The scan lid open condition is detected by aligning two scan bars with one another, illumining one of the scan bars with a predetermined illumining pattern and during the illumining, scanning the illumined scan bar with the other scan bar. The response of the scanning scan bar is compared with an expected response for the illumining pattern with the scan lid closed. If a positive comparison occurs, the scan lid is closed. If a negative comparison occurs, the scan lid is open.
