Filed: 1990-09-05
Abstract: PURPOSE:To allow an original carrier master CPU to be restored to the operating mode automatically in the case of a tentative reception error by providing a reset restoration means to a main body master CPU. CONSTITUTION:An original carrier master CPU 220 controls original exchange of an original carrier while exchanging information with a main body master CPU 140 and reaches the reset state when a reception error takes place. The CPU 140 executes an initial command monitor processing after the execution of initialize processing to the CPU 220 in the reset state. Then the CPU 140 detects whether or not the reception error causing the reset is able to be restored and displays a service man call message when the restoration is disabled. On the other hand, when the reception error is temporary, the CPU 140 displays a jam occurrence message and sends a destination data and the mode data. Thus, the CPU 220 is restored to the operating mode.
