Markierungsbelegleser OMR C


High-performance scanners are employed where large quantities of documents are to be archived digitally as images and, when required, evaluated according to defined criteria and then respectively sorted.

The images are thereby prepared by means of CCD or CIS line cameras and integrated image processing boards (IPB). The interpretation of the images is effected by a PC with ideally suited application software. Time-critical interpretation processes can already take place in the image processing board.

Besides their high throughput rate (up to 360 documents/minute), automatic document feed from a stack as well as the scanning of the front and back sides of the document in a single run, high-performance scanners also feature document output in sorting trays.

High-performance scanners can even transport, record and process folded documents or documents of varying sizes and thicknesses in one and the same run. In contrast to optical mark readers (OMRs), high-performance scanners do not require formatted, specially designed documents.



Optical mark recognition is the fastest and most reliable method of recording and digitally preparing those volumes of data that are present as marks on paper-based, formatted documents and forms. Marks are crosses, bars or bubbles made by pencils or ballpoint pens at precisely defined positions on the document intended for that purpose.

Optical mark readers check only these defined document positions and recognize any marks that are present on the basis of reduced light reflection. The marking coordinates are transmitted to a PC. The interpretation of the marking coordinates is effected completely or partially by means of application software. 

Optical mark recognition presupposes specifically formatted data carriers (documents) that are precisely adapted to the respective application. As opposed to scanning, in optomechanical mark recognition no digital image is produced.
