A user uses a control panel (13) to specify quick memory transmission and instruct the machine to begin the procedure. The first page of the document is scanned in by a scanning unit (14) and stored in a image memory (19). Upon storing of the image of the first page of the document in the image memory (19), NCU (17) automatically dials a transmission recipient. Additionally, a monitoring unit (16) allows the user to hear the sounds of the communication signals at the start of transmission. If, during the scanning of a second, third, or later page of a multi-page document, free space in the image memory (19) falls below a given value, then the page at which the memory became full is indicated to the user, thereby indicating the page at which retransmission should begin.
