Aim deviation is the top fault of arcade shooting games. Most aiming problems can be solved through standard gun calibration, instead of replacing hardware. Shooting game technical adjustment includes light sensor calibration, screen brightness and ambient light compensation.
Turn on the machine and enter gun calibration mode. Follow on-screen prompts to shoot each calibration target. Do not stand too close or too far during calibration. Strong venue lighting, spotlights and direct sunlight will interfere with infrared light sensors, causing aiming offset.
Adjust screen brightness and contrast. Too dark screens reduce sensor recognition; over-bright screens create reflection noise. Keep consistent lighting around the cabinet after finishing calibration.
Check gun lens regularly. Dust and scratches block light signals and break calibration results. If calibration still fails, inspect wiring between gun and mainboard.
Q: Gun works fine in daytime but inaccurate at night?
A: Ambient light change affects optical sensors. Re-run calibration after venue lighting schedule changes.
Q: How many guns can be calibrated on a 4-player shooting machine?
A: Each gun needs independent calibration in the service menu.
