Abstract (en)

Systems and methods are provided for aligning printheads of a printing system. One embodiment is a system for aligning printheads of a printing system. The system includes a first sensor configured to detect lateral positions of an upstream printhead relative to sections of a web of print media traveling through the printing system, and a second sensor configured to detect lateral positions of a downstream printhead relative to the sections of the web. The downstream printhead is placed after the upstream printhead in the direction of travel of the web. The system also includes a controller configured to align the downstream printhead with the sections of the web based on the lateral positions of the upstream printhead and the lateral positions of the downstream printhead.
