恰當的 NC-UV0609MAX-II Y-axis motor replacement​ restores stable front-back platform movement on this 600×900 mm industrial UV printer. NC-UV0609MAX-II使用Epson 13200-U1白色, 13200-U1HD 顏色和 11600-U1 清漆, 以 720×600/900/1200 dpi 運行 CMYK+LC+LM+LK+LIK+W+V, 柔性印刷 22, 470瓦, 交流220/110V, 負壓環保UV墨水, 25–28°C / 35–65% 相對濕度. 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.

準備

關閉電源, 拔下電源插頭並檢查接地情況. 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

打開後檢修面板，露出 Y 軸驅動組件. 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

重新連接電源並開啟印表機. Run the platen initialization routine from the panel; the flatbed should move forward and backward smoothly without hitting limits early. 如果錯誤 121/122 出現, 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.

更換後護理

第一個小時監控平台運動. Re-tighten the coupling after about 8 營業時間, then inspect monthly. Keep the rear drive area free of dust and ink mist, 並保持25–28°C / 35–65% 相對濕度. Use only Nocai original motor and eco UV ink to protect Y-axis accuracy and after-sales support.
