An automatic fastener driving tool with an automatic side-loading magazine can be automatically loaded with fasteners via a high-capacity automatic loading station. The tool and the magazine are moved proximal to the loading station. The magazine door is automatically opened, and the loading station pushes fasteners into the magazine. The magazine door is automatically closed, and the tool and the magazine are moved back to their original position.
