- When the power is on, Vacuum and LED Lamp are normal, but only the touch panel does not turn on.
- When the ARTJET software is running but only displays Offline status.
- When there is no response even after reconnecting the USB or rebooting the power.
- Users considering replacing the mainboard due to suspicion of a defect.
Mainboard, USB board, and Touch Panel boards are expensive components.
✔ Do not start by disassembling the unit unconditionally.
✔ First, check whether the 24V voltage is cut off.
✔ It is very risky to judge a board as defective before checking the status of the Emergency button.
Misdiagnosing a simple power cutoff as a board defect will result in unnecessary costs.
- The touch panel power structure is Main Board → 24V Supply.
- Vacuum/LED Normal + Panel Only OFF → High probability of voltage cutoff.
- If the Emergency button is activated, the 24V is cut off.
- Checking the cutoff circuit takes priority over board defect diagnosis.

Comprehensive list of products you can manufacture with a UV Printer
I. Problem Symptoms — Touch Panel Power Not Turning On
1. Current Situation
“When I run the ARTJET software, there is no operation and it says Offline.”
“I see. Could you try unplugging and replugging the USB? Before you do that, please turn off the entire printer power and turn it back on.”
“I’ve tried that, and I’ve also tried plugging the USB into a different port, but it’s not resolved.”
2. Further Verification
“Sir, are there any other symptoms?”
“Actually, the Vacuum and LED lamp are getting power normally, but the touch panel won’t turn on. The light on the Power button is on, though.”
“There is a wire that supplies electricity to the touch panel, and it seems the power is not reaching it. Would you like to try unplugging and replugging that wire?” After that, I explained how to disassemble the unit to see the bottom of the touch panel. Later, I was contacted again.
“Team leader, I tried it, but it’s still not fixed.”
II. Resolution — Touch Panel Power Issue
1. Main Board and Touch Panel Board
The ARTJET board is mainly composed as follows:
- Main Board: Mounted on the back of the printer, primarily responsible for motion.
- USB Board: Mounted on the back of the printer, receives Ripping DATA and transmits DATA to the Carriage board.
- Carriage Board: A board on top of the head carriage, receives ripping data from the USB board and delivers it to the print head.
- Touch Panel Board: The touch panel board on the front of the printer; it contains simple operation buttons, but if this board has an issue, initializing will not occur.
24 Voltage enters the Main Board, and the Main board’s 24 Voltage is transferred to the Touch Panel Board to supply power to it.
2. Main Board and Touch Panel Board that Never Had Issues
Since these boards had never been an issue before, I was quite perplexed. Suddenly, one suspicion came to mind.
“Hello, sir?” “I’m not doing so well. Ha ha ha.”
“Could you try pressing the Emergency button and then releasing it again?”
“Pardon?”
“In the past, when I went to install equipment, there was a symptom just like yours. The Vacuum and LED were normal, but even when the Power button was pressed (and the button light was normal), the touch panel wouldn’t turn on.”
“Previously, when removing the printer cover, I cut the Emergency button wire and taped it back together…”
“Then please remove the tape and check the connection status.”
Five minutes later, the customer called.
“What should I do?… It works immediately.”
“That’s a relief, sir.”
“The part I had taped together had come apart.”
In the end, the Emergency button was activated, cutting off the 24 voltage, and it was resolved by releasing/reconnecting it.
