4.3 Input/output (I/O) specifications
When handling external signals, observe the voltage, current, and time given in this manual.
Operation is not guaranteed if external signals are not handled properly.

The deflection voltage is turned on
(Ready) and off (Standby) alternately
each time this signal is entered.
*1) The current supply capacity of +24V for Print object detector and encoder is up to 100mA in total.
*2) RUN signal instructs to inkjet ink. Handle the signal with care.
*3) Ensure that the external device transistor leak current doesn't exceed 0.1mA while the input signal is OFF.
