4.3.1 Print target detector input

This function inputs the IJ printer print start signal.
Use a no-contact (transistor) type print target detector. An optoelectronic sensor with built-in amplifier
which uses a light beam to detect the print target is ideal. When the total current consumption of the print
target detector and the rotary encoder is 100mA or less, power can be supplied from the power supply
built into the IJ printer. When the total current consumption exceeds 100mA, provide a dedicated power
supply.
In this case, perform wiring and setting as described below.
