Proper NC-UV0609MAX-II Power Supply Unit Replacement​ restores stable AC-DC power for the 600×900 mm industrial UV printer. The NC-UV0609MAX-II uses Epson 13200-U1 white, 13200-U1HD color and 11600-U1 varnish, runs CMYK+LC+LM+LK+LIK+W+V at 720×600/900/1200 dpi, FlexiPRINT 22, 470W, AC 220/110V, negative-pressure eco UV ink, 25–28°C / 35–65% RH. The power supply box feeds the main board, motors, UV lamps and sensors. A failed unit causes no boot, dark power LED, random resets or component damage. Because the cabinet carries high voltage, replacement should follow the Nocai procedure or a qualified technician.

Preparation

Disconnect the mains cable from the wall and the machine. Wait a few minutes for capacitors to discharge, then wear insulated gloves. Prepare a genuine Nocai PSU matched to the nameplate voltage, Phillips driver, camera, cable labels and a multimeter. Open the electrical cabinet only after confirming ground and power-off status.

Remove the old PSU

Photograph every cable before disconnecting. Unplug the AC input first, then DC outputs to the main board and subsystems. Remove the fixing screws and lift the old box out without pulling the wires. Check the terminals, ground wire and cable jackets for burn marks, looseness or ink contamination.

Install the new PSU

Mount the OEM unit in the same orientation and tighten screws evenly. Reconnect DC output connectors first, then the AC input, and confirm the ground wire is seated. Verify the voltage selector matches local mains—110V or 220V. Double-check that no plug is reversed; a wrong connection can damage the board.

Boot and test

Reconnect mains power and switch the printer on. The control panel should boot and the power LED should light. Measure output with a multimeter if required by the service checklist, then run a nozzle check and print a test pattern. Stable initialization completes the NC-UV0609MAX-II Power Supply Unit Replacement.

Post-replacement care

Keep the electrical cabinet dry and dust-free. Inspect screws, grounds and cable ties monthly, and avoid unstable generators or poor grounding. Use only Nocai eco UV ink to keep after-sales support valid.
