Richtig NC-UV0609MAX-II Y-axis motor replacement​ restores stable front-back platform movement on this 600×900 mm industrial UV printer. Der NC-UV0609MAX-II verwendet Epson 13200-U1 Weiß, 13200-U1HD-Farbe und 11600-U1-Lack, Läuft CMYK+LC+LM+LK+LIK+W+V mit 720×600/900/1200 dpi, FlexiPRINT 22, 470W, Wechselstrom 220/110 V, Unterdruck-Öko-UV-Tinte, 25–28°C / 35–65 % relative Luftfeuchtigkeit. The Y-axis motor sits at the rear of the machine as the “platform motor” and drives the flatbed through a screw/spiral guide. A failing motor causes erratic moves, initialization failure, Y misregistration or platen limit errors. Fitting an OEM Nocai motor returns accurate bed positioning.

Vorbereitung

Ausschalten, Ziehen Sie den Netzstecker und überprüfen Sie die Erdung. Wear antistatic gloves and ensure good lighting. Move the platform to the front service position. Photograph the motor, coupling, cable route and mounting bolts. Prepare an OEM Nocai Y-axis stepper motor, hex keys, Phillips driver, needle-nose pliers and a torque wrench if available. Do not touch the printheads, encoder parts or ink lines during setup.

Remove the old motor

Öffnen Sie die hintere Zugangsklappe, um die Y-Achsen-Antriebsbaugruppe freizulegen. Disconnect the motor signal and power cable from the mainboard. Loosen the coupling set screws that link the motor shaft to the drive shaft, then unbolt the motor bracket and lift the old unit out. Note the motor orientation, spacer placement and coupling position. Check the coupling, shaft plane and cable for ink mist, looseness or impact marks.

Install the new motor

Mount the OEM motor in the same orientation with spacers in place. Tighten bracket bolts evenly so the motor shaft aligns with the drive shaft front-to-back and top-to-bottom. Refit the coupling centered between motor and drive shaft, then lock the coupling screws. Reconnect the motor cable firmly and route ties away from moving parts. If the unit uses a belt sub-drive instead of direct screw coupling, seat the belt without twist and adjust tension per manual.

Initialize and calibrate

Schließen Sie die Stromversorgung wieder an und schalten Sie den Drucker ein. Run the platen initialization routine from the panel; the flatbed should move forward and backward smoothly without hitting limits early. Wenn Fehler 121/122 erscheint, recheck the platen limit sensor cable and position. Print a fine horizontal-line test pattern to verify Y registration. Stable, aligned output completes the NC-UV0609MAX-II Y-axis motor replacement.

Betreuung nach dem Wechsel

Überwachen Sie die Plattformbewegung in der ersten Stunde. Re-tighten the coupling after about 8 Betriebsstunden, then inspect monthly. Keep the rear drive area free of dust and ink mist, und halten Sie die Temperatur bei 25–28 °C / 35–65 % relative Luftfeuchtigkeit. Use only Nocai original motor and eco UV ink to protect Y-axis accuracy and after-sales support.
