① Keep the power cable to the unit away from other power supply cables (in particular, a speed control inverter
power supply cable, etc.). Putting them into different ducts provides better performance.
② Wire input/output (I/O) signal cables individually. Do not bundle them together with other power supply
cables.
③ Electrically isolate the print target detector, print head, stand, and main body from other machines (such as a
conveyor).
④ Keep the wiring of print target detector away from other power supply cables.
⑤ Ensure that all electrical wiring, connections, and grounding comply with applicable cords. If a malfunction
occurs due to noise, make a separate ground connection.
