Abstract
A method and apparatus for facsimile transmitting having an error retransmission function. A page of information is divided into a plurality of frames. The frames are transmitted on a block-by-block basis with each block having a predetermined number of frames. The information is received at a receiving station and checked for errors. If errors are present an indication is submitted back to the transmitting station so that the frames having errors can be retransmitted. A plurality of buffers is provided so that the first information can be transmitted from a first buffer while the next image information is being encoded and stored in a second buffer.
