恰当的 NC-UV0406-VI Light grating sensor replacement​ restores reliable X-axis feedback for the dual Epson I1600-U1 printheads. NC-UV0406-VI是一款400×600毫米平板A2桌面UV打印机, 0–180 毫米高度, CMYK+W 或 CMYK+W+V 最多 1200 分辨率, FlexiPRINT MiniServer 22 Nocai Edition, 143瓦, 交流220/110V, 和生态UV墨水; 25–28°C 时效果最佳 / 35–65% 相对湿度. 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.

准备

关闭打印机电源并拔掉电源插头. 戴防静电手套. Open the cover and move the carriage to the middle of the beam. Prepare a Phillips driver, 镊子, 无绒湿巾, ≥99%异丙醇, and a new OEM light grating sensor specified for NC-UV0406-VI. Photograph the sensor bracket, 电缆路线, 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. 断开传感器电缆与主板或中间连接器的连接. Remove the mounting screw and lift the old unit straight out. Inspect the lens, flexible cable, and bracket for ink mist, 划痕, or looseness. Never touch the grating scale with bare hands. If only dust affects reading, clean first and retest before replacement.

安装新传感器

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, 紫外线灯, 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.

更换后护理

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% 相对湿度, and use only Nocai original sensors, ink, and spare parts to maintain accuracy and warranty support.
