Abstract

PURPOSE: To secure the easy detection and recovery for most of the faults by providing the display unit corresponding to each print panel on the print panel and then lighting up the display unit when the error is generated.
CONSTITUTION: Display unit 3 comprising three display units A, B and C is provided at the corresponding parts of pring panels 1aW1i. At the same time, the error detecting circuit is formed with error detection signal 4, error types 5W7, flip-flop circuit 8, 8' and 8" plus light emitting diodes 9, 9' and 9" each. The generation signals sent from panel 1 are classified into the error through the parity check, the error on the sequence and the interface error each. For these errors, the logic sum is secured with every classification, and then flip-flops 8, 8' and 8" are set to turn on the light emitting diodes. In case the fault occurs, either one of A, B and C of the diodes is lit up. Thus the type of the error and print panel of the error are detected, and the fault is recovered through exchange.
