Approprié NC-UV0609MAX-II Origin sensor replacement​ restores reliable carriage homing on this 600×900 mm industrial UV printer. The NC-UV0609MAX-II prints 0–180 mm height, utilise Epson 13200-U1 blanc, 13200-Couleur U1HD et vernis 11600-U1, exécute CMYK+LC+LM+LK+LIK+W+V à 720×600/900/1200 dpi, Miniserveur FlexiPRINT 22, 470W, CA 220/110 V, encre UV écologique à pression négative, 25–28°C / 35–65% HR. Le capteur d'origine détecte la référence du chariot au démarrage; offset, damage or signal loss causes error 107 zero-point faults, failed homing, crashes near the ink station, or wrong start margins. Fitting a genuine Nocai sensor returns stable registration.

Préparation

Power off, unplug and verify grounding. Press emergency stop if fitted, porter des gants antistatiques, and prepare a Phillips driver, pince à épiler, lingettes non pelucheuses, ≥99 % d'alcool isopropylique, a multimeter and the NC-UV0609MAX-II manual. Move the carriage away from the home side through the panel or by hand after power isolation. Photographiez le support du capteur, chemin de câble, connector and flag position before removal.

Fault confirmation

Run homing and check symptoms: no home position, X-axis value not updating, repeated origin errors, or carriage crashing after moving left/right. The MAX-II manual lists origin-sensor offset, origin-sensor replacement, origin-sensor cable replacement and cart-board replacement for such faults; error 107 indicates abnormal origin cart-sensor signal, while 108 points to encoder issues rather than the origin switch. Clean the sensor window first—ink dust can mimic failure.

Remove the old sensor

Disconnect the origin-sensor cable from the mainboard or intermediate connector and label it. Dévissez le capteur de son support, noter la direction de détection, and lift the old unit out. Inspecter l'objectif, câble, bracket and carriage flag for ink mist, looseness or physical damage. Do not bend the cable or touch nearby encoder strip during removal.

Install the new sensor

Fit the OEM Nocai origin sensor in the original orientation. Alignez sa fente ou sa face de détection avec le drapeau du chariot/la cible réfléchissante, keep the recommended gap per manual, and tighten screws lightly to avoid tilt. Reroute the cable away from the X-axis belt, carriage path and UV lamp area, then lock the connector. Confirm the sensor does not contact the moving flag.

Homing and alignment test

Release emergency stop, power on, and run the homing sequence; the carriage should move to the origin and stop precisely without overshoot. Move left/right to confirm X-axis values update smoothly. Dans FlexiPRINT, print nozzle, step and alignment patterns; si la marge de départ dérive, ajuster le décalage d'origine dans le menu de service. Lorsque le référencement est stable et que l'enregistrement est correct, the NC-UV0609MAX-II Origin sensor replacement​ is complete.

Soins post-remplacement

Wipe the sensor window weekly with alcohol, keep the flag free of ink dust, and check cable ties and bracket torque monthly. Service rails, bande d'encodeur, belt and ink station per manual, use only Nocai original sensors and eco UV ink, et maintenir 25-28°C / 35–65% HR.
