Apropriado NC-UV0609MAX-II Y-axis motor replacement​ restores stable front-back platform movement on this 600×900 mm industrial UV printer. 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. 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.

Preparação

Desligar, desconecte e verifique o aterramento. Wear antistatic gloves and ensure good lighting. Move the platform to the front service position. Fotografe o motor, coupling, cable route and mounting bolts. Prepare an OEM Nocai Y-axis stepper motor, chaves hexagonais, Motorista Phillips, 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

Abra o painel de acesso traseiro para expor o conjunto da unidade do eixo Y. 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

Reconecte a alimentação e ligue a impressora. Run the platen initialization routine from the panel; the flatbed should move forward and backward smoothly without hitting limits early. Se erro 121/122 aparece, recheck the platen limit sensor cable and position. Print a fine horizontal-line test pattern to verify Y registration. Estável, aligned output completes the NC-UV0609MAX-II Y-axis motor replacement.

Cuidados pós-substituição

Monitore o movimento da plataforma durante a primeira hora. Re-tighten the coupling after about 8 horário de funcionamento, then inspect monthly. Keep the rear drive area free of dust and ink mist, e manter 25–28°C / 35–65% UR. Use only Nocai original motor and eco UV ink to protect Y-axis accuracy and after-sales support.
