The Tango scanner, which was later renamed Primescan, is a drum scanner with a vertical drum, requiring only a small floor area. The scanner has only a scanning drum, and it is linked to a computer which stores the scanned pictures digitally. By means of a job planning software, many pictures, which are mounted on the drum, can be scanned and stored automatically with different scale factors. The pictures can be scanned with a very high resolution, up to 11,000 dpi.

As usual today, further processing of the pictures like color separation, color correction, and screening is done by software.
