Abstract
A facsimile transmission system is used to transmit documents over telephone lines using an electronic mail system, which may be a localized system or a distributed electronic mail system. Transmission is initiated by the sending facsimile machine transmitting a mark sense cover sheet, which has a mark sense identifier printed on it, to a facsimile controller. The controller checks for the presence of the mark sense identifier and if present, the controller reads the identifying information and destination address coded thereon. The controller then transmits the identifying information and destination address and the subsequently received document facsimile data to the electronic mail system in digital form, for retransmission back through the same or a different controller to one or more receiving facsimile machines.
