Apropriado NC-UVDTF60 A substituição do motor do eixo X é necessária quando o carro se move de forma irregular, emits grinding or squealing noises, falha ao inicializar, or triggers persistent X-axis position errors that cleaning and belt adjustments cannot resolve. The X-axis motor drives the printhead carriage across the 60 cm beam; a failing motor causes banding, registro incorreto, and collision risks. The NC-UVDTF60-PLUS user manual requires powering off the machine before any cleaning or repair, and mandates original NOCAI accessories and ink—using non-NOCAI ink voids after-sales service. Replacing the motor restores accurate, quiet carriage motion. Because the procedure involves the electrical and motion system, it should be performed by trained personnel or under the guidance of your local NOCAI distributor.

Preparação

Primeiro, switch off the printer and unplug the power cord. Próximo, put on anti-static gloves and prepare a clean, well-lit workbench. You will need the compatible genuine NOCAI X-axis motor, an Allen wrench, a Phillips screwdriver, etiquetas de cabos, a camera or smartphone for photos, and the user manual.

Removendo o motor antigo

Open the side panel to expose the drive assembly. Before disconnecting any cables, photograph each connector and label the plugs clearly. Então, disconnect the motor cables from the main board and loosen the coupling or tensioner connecting the motor to the carriage. After removing the mounting bolts, carefully lift out the old motor, noting its orientation and any spacers.

Instalando o novo motor

Position the new motor in the exact same direction as the old one, ensuring any washers or shims remain in place. Hand-tighten the bolts first, então proteja-os totalmente. Reconnect the coupling or adjust the belt tension so that the belt deflects 5–8 mm when pressed in the middle. Finalmente, reconnect the motor cables, route the wires away from moving parts, and verify that no plug is reversed.

Teste e calibração

Reapply power and jog the carriage manually across the full beam width. O movimento deve ser suave e silencioso. Subsequently, run the auto-alignment routine from the service menu and print a test pattern with fine vertical lines to verify bidirectional registration. Se as faixas persistirem, recheck the alignment and tension. Once the motion is stable, the NC-UVDTF60 X-axis motor replacement​ is complete.

Cuidados pós-substituição

Monitor the carriage for the first hour of operation. After eight hours, re-tighten any couplings or belt tension. Adicionalmente, periodically inspect the motor cable inside the drag chain for wear. Please note that the one-year warranty excludes ink-related parts, and non-NOCAI ink may void support.
