Non-single network port model setting method
S1 Open the V3.1C tool
S2 The communication port selects the remaining interfaces,which can be USB/serial/parallel
S3 Modify the IP address at the“New IP”and click Set New IP (see Figure 2).
S4 The buzzer sounds and the printer restarts to indicate that the setting is successful
