Use these recommended system requirements for most newer workgroup and department level scanners capable of scanning 30 pages per minute (PPM) or more. A recommended ccScan computer is a dual core processor with 2.0+ GHz or higher processor speed, 4 GB memory and 20+ GB free hard drive space. The Windows 7 or Window 10 operating system is recommended. Almost any PC computer purchased within the last 3 years will be close to or higher than these requirements.
