Hitachi UX2 - Print Target Detector Input

4.3.1. Print Target Detector Input
The print target detector input function is used to input the start print signal of the IJ Printer. Use a no-contact
(transistor) type output for the print target detector. An optoelectronic sensor with built-in amplifier that
detects a print target with an optical beam is the most suitable. When the power consumption of the print
target detector and rotary encoder is 100 mA or less in total, power can be supplied from the IJ Printer built-in
power supply. When it exceeds 100 mA in total, provide a dedicated power supply. The wiring and settings in
this case are shown below.
