The Crowley C400 Advanced is a production aperture card scanner designed for organisations that need to digitize large collections of 35 mm aperture cards quickly, accurately, and efficiently. Developed for engineering firms, manufacturers, government agencies, archives, and records management providers, it combines advanced automation with professional image quality to streamline technical document preservation.

Designed to support all ISO-standard aperture card formats, the C400 Advanced captures both high-resolution 35 mm microfilm images and Hollerith punch data in a single workflow. Automated Hollerith data recognition simplifies indexing, file naming, and document management, reducing manual processing while improving searchability and operational efficiency.

The scanner features an upgraded imaging system, enhanced lighting, redesigned internal mechanics, and a 300-card automatic feeder that enables unattended batch scanning for high-volume projects. A manual feed mode is also available for individual scanning tasks.

Advanced image enhancement tools optimise scan quality during capture, while the integrated virtual rescan function allows operators to reprocess previously scanned images using different imaging settings without rescanning the original aperture card. This helps protect valuable source material and supports long-term preservation initiatives.

Supporting output formats including TIFF, JPEG, and searchable PDF, the C400 Advanced is well suited for digitising engineering drawings, blueprints, schematics, facility records, and historical technical archives. Combining reliable automation, professional image quality, and efficient workflow management, the Crowley C400 Advanced provides a scalable solution for converting aperture card collections into accessible digital archives.
