*1. There are four output signal types of [PREND] for the 6th pin. Select one of them based on [External signal
type] in [3.8 Advance Mode].
*2. When setting JP8 to [2-3] side, the power will be supplied from EXT5V_IN(Pin No. 8).
When setting JP8 to [1-2] side, the printer will be powered by the internal power supply.
When setting JP7 to [1-2] side, the printer will be used for offline output.
When setting JP7to [2-3] side, the 9th pin will be used for input.
Note:
External signal may become unstable for a second or so after turning the power on. Wait more than one
second before starting the operation control.
