Arcade operators ensure light gun accuracy through a combination of regular calibration, sensor maintenance, and software updates. Calibration involves adjusting the gun's alignment with the screen to guarantee precise targeting. Operators frequently test infrared or optical sensors to detect and resolve any inconsistencies. Additionally, firmware updates are applied to address bugs or improve performance. Routine cleaning of lenses and screens also prevents interference, while periodic hardware inspections identify wear and tear. By adhering to these technical practices, arcade operators deliver a seamless and immersive shooting experience for players.
