Richtig NC-UV0406-VI Light grating sensor replacement​ restores reliable X-axis feedback for the dual Epson I1600-U1 printheads. Der NC-UV0406-VI ist ein A2-Desktop-UV-Drucker mit 400×600 mm Flachbett, 0–180 mm Höhe, CMYK+W oder CMYK+W+V bis zu 1200 dpi, FlexiPRINT MiniServer 22 Nocai-Ausgabe, 143W, Wechselstrom 220/110 V, and eco UV ink; it works best at 25–28°C / 35–65 % relative Luftfeuchtigkeit. The light grating sensor reads the encoder strip and reports carriage position. A failed sensor causes drift, banding, wrong margins, or homing faults. Fitting a genuine Nocai sensor returns stable positioning.

Vorbereitung

Schalten Sie den Drucker aus und ziehen Sie den Netzstecker. Tragen Sie antistatische Handschuhe. Open the cover and move the carriage to the middle of the beam. Prepare a Phillips driver, Pinzette, fusselfreie Tücher, ≥99% isopropyl alcohol, and a new OEM light grating sensor specified for NC-UV0406-VI. Photograph the sensor bracket, Kabeltrasse, and connector position. Check the grating strip for dust or damage before replacing the reader.

Removing the Old Sensors

Locate the light grating sensor on the carriage body facing the encoder strip. Trennen Sie das Sensorkabel vom Mainboard bzw. Zwischenstecker. Remove the mounting screw and lift the old unit straight out. Inspect the lens, flexible cable, and bracket for ink mist, Kratzer, or looseness. Never touch the grating scale with bare hands. If only dust affects reading, clean first and retest before replacement.

Installieren des neuen Sensors

Mount the new OEM sensor in the original orientation. Position its emitting/receiving face parallel to the grating strip and set the gap per the Nocai manual—verify the exact value for NC-UV0406-VI. Route the cable away from the carriage path, UV lamp, and power harness. Tighten screws lightly to avoid tilting. Confirm the sensor sits centrally in the strip window and does not contact the scale.

Homing and Accuracy Test

Power on and run the homing sequence; the carriage should read position smoothly without jumps. In FlexiPRINT, print an alignment grid and a ruler pattern, then measure printed size against design size. If margins drift, adjust the grating-sensor offset or recheck gap and connector. When X-axis feedback is stable and output size matches, the NC-UV0406-VI Light grating sensor replacement​ is complete and the printer is ready for production.

Pflege nach dem Ersatz

Keep the grating strip and sensor window clean with isopropyl wipes. Avoid pressing the carriage against the strip. Run weekly position checks under 25–28°C / 35–65 % relative Luftfeuchtigkeit, and use only Nocai original sensors, ink, and spare parts to maintain accuracy and warranty support.
