Device and method for scanning large-format documents

Abstract

A method for scanning large-format documents by way of a large-format scanner, which is connected to a PC (11) via a standard interface (10), is to be further developed, so as to omit prescans, to optimize the scanning rate, to significantly increase productivity between the application of the document and the storage of the data on the PC, and to obtain cost-efficient scans. It is disclosed that upon inserting (1) the documents into the large-format scanner a broadness detection (2) takes place, depending on said broadness detection (2) areas of at least one image detection element which are not required because said areas are not confronted with the document will be turned off (3) in order to reduce the band width of the scanned data, the document will be scanned (7), the scanned data will be transmitted via the standard interface (10), a continuous control of the maximum amount of data which can be transmitted takes place during data transfer (10) and depending on the control result the rate of the document feeding is affected.
