The motherboard coordinates the printhead, X/Y motors, sensores, UV system and ink supply. O NC-UV0609MAX-II usa Epson 13200-U1 branco, 13200-Cor U1HD e verniz 11600-U1, executa CMYK+LC+LM+LK+LIK+W+V a 720×600/900/1200 dpi, FlexiPRINT 22, 470C, CA 220/110 V, tinta eco UV de pressão negativa, 25–28ºC / 35–65% UR. A failed board causes no boot, lost subsystem communication or persistent fault codes. Because board work involves critical circuits, replace it with trained staff or Nocai dealer guidance.

Preparação

Power off and unplug the mains cable. Wait for capacitors to discharge, then wear an antistatic wrist strap and gloves. Prepare a clean static-free workspace, an OEM Nocai motherboard matched to the machine revision, Phillips drivers, pinça, etiquetas de cabos, a camera and the user manual. Open the rear electrical cabinet only after confirming no live voltage.

Remove the old board

Photograph every connector before disconnecting anything. Unplug cables from the outermost ports first—power, rede, motor, sensor, printhead carriage and UV control—and label each plug. Remove the ground screw, então os parafusos de montagem. Lift the old board by its edges only; never touch gold contacts or ICs with bare hands. Check terminals for burn marks, dust or ink mist.

Install the new board

Mount the OEM board in the exact orientation of the old one. Hand-tighten screws first, then secure fully. Reconnect the ground wire first and lock it, then follow photos and labels to seat every plug. Route cables neatly so no connector is stressed. Verifique novamente se nenhum plugue está invertido e nenhum conector sobressalente foi esquecido.

Boot and calibrate

Reconnect mains power and switch the printer on. O painel de controle deve inicializar normalmente. If it fails to initialize, power off and recheck cable mapping. Run the calibration wizard in FlexiPRINT to reset printhead, motor and sensor parameters, then print a comprehensive test pattern. Stable boot completes the NC-UV0609MAX-II Motherboard Replacement.

Cuidados pós-substituição

Keep the electrical cabinet dry and dust-free. Inspect grounds, screws and connectors monthly, and avoid unstable mains or poor grounding. Keep reference photos for future service. Using non-Nocai ink may void after-sales support.
