Thích hợp NC-UV0609MAX-II Light grating sensor replacement​ restores X-axis reading on this 600×900 mm industrial UV printer. The machine prints 0–180 mm height, uses industrial Epson heads per BOM—commonly 13200-U1 white, 13200-Màu U1HD và sơn bóng 11600-U1, or I3200/I3200-HD/I1600 configurations—runs CMYK+LC+LM+LK+LIK+W+V at 720×600/900/1200 dpi, Máy chủ mini FlexiPRINT 22, 470W, AC 220/110V, Mực UV sinh thái áp suất âm, 25–28°C / 35–65% RH. The light grating sensor reads the encoder strip; failures cause position jumps, ghosting or homing errors. An OEM Nocai reader returns smooth feedback.

Sự chuẩn bị

Tắt nguồn, rút phích cắm và xác minh nối đất. Wear antistatic gloves and work in clean light. Through the panel, trình điều khiển hoặc FlexiPRINT, park the carriage mid-beam. Prepare an OEM Nocai grating sensor, small Phillips driver, nhíp, khăn lau không có xơ, ≥99% isopropyl alcohol and bracket photos. Do not touch the encoder strip or X-axis limit switch during setup.

Tháo cảm biến cũ

Open the cover, locate the reader on the carriage facing the encoder strip, disconnect its ribbon or cable, label the connector, and unscrew the bracket. Lift the old unit straight out. Inspect the optical window, cable and bracket for ink mist, scratches or looseness. If only dust causes errors, wipe the strip and window with alcohol in one direction, then retest before replacing.

Cài đặt cảm biến mới

Mount the OEM sensor in the original orientation. Align its optical window with the encoder strip, keep the gap per manual—Nocai same-series guidance commonly uses 1–2 mm—and tighten screws lightly to avoid tilt. Định tuyến lại cáp ra khỏi đai trục X, carriage path and UV lamp, sau đó khóa đầu nối. Confirm the reader sits centrally in the strip slot and never contacts the scale.

Encoder test and alignment

Reconnect power and enter the service menu; run “Encoder Test” or equivalent, then move the carriage across the full width. The X-axis readout should stay positive and increase smoothly without jumps. Chạy tự động dọn dẹp, print a nozzle test, step grid and alignment pattern; measure printed size against design. If drift remains, recenter the sensor, recheck the gap and cable. Stable readings complete the NC-UV0609MAX-II Light grating sensor replacement.

Chăm sóc sau thay thế

Wipe the encoder strip and sensor window with alcohol in one direction weekly, schedule strip cleaning about every 500 giờ hoạt động, and monitor carriage noise for the first hour. Đường ray dịch vụ, ink station and cap top per manual, use only Nocai eco UV ink and original sensors, và duy trì 25–28°C / 35–65% RH.
