Abstract

팩시밀리에서 다중원고를 송수신하는 중에 원고의 페이지간에 전송모드의 변환이 이루어질 경우 이전 페이지의 원고를 송수신시 에러가 발생하였던 전송속도부터 트레이닝함으로써 고장대치가 발생하는 이전의 에러를 다시 반복하게 됨에 따라 통신시간이 연장되는 것을 개선한다. 이를 위하여 다중원고 송수신을 위해 처음의 트레이닝 모드를 수행하는 것에 의해 결정된 전송속도를 최적 전송속도로 저장하고 그에 따른 전송속도를 선택하여 원고를 송수신하며 원고를 송수신하는 중 페이지간에 전송모드가 변환되는 것에 응답하여 저장되어 있는 최적 전송속도부터 트레이닝 모드를 수행한다. 따라서 다중원고를 송수신할 때 원고의 페이지간에 전송모드의 변환이 이루어질 경우 처음의 최적 전송속도부터 트레이닝을 함으로써 불필요한 재트레이닝으로 인해 통신시간이 길어지는 것을 방지한다.If the transmission mode is changed between pages of the original while the fax is transmitting or receiving multiple originals, the previous error that caused the fault replacement is repeated by training from the transmission speed at which the error occurred when transmitting or receiving the original page. Improve the time extension. To this end, the transmission rate determined by performing the initial training mode for multiple document transmission and reception is stored at the optimum transmission rate, and the transmission mode is switched between pages during the transmission and reception of originals by selecting the transmission rate accordingly. The training mode is executed from the optimal transmission rate stored in response. Therefore, when the transmission mode is changed between pages of the original when sending and receiving multiple originals, the communication time is prevented from being elongated due to unnecessary retraining by training from the initial optimum transmission speed.
