سليم NC-UV0609MAX-II Light grating sensor replacement​ restores X-axis reading on this 600×900 mm industrial UV printer. تطبع الآلة ارتفاعًا من 0 إلى 180 ملم, uses industrial Epson heads per BOM—commonly 13200-U1 white, 13200-لون U1HD ورنيش 11600-U1, or I3200/I3200-HD/I1600 configurations—runs CMYK+LC+LM+LK+LIK+W+V at 720×600/900/1200 dpi, خادم FlexiPRINT الصغير 22, 470دبليو, تيار متردد 220/110 فولت, حبر UV صديق للبيئة ذو ضغط سلبي, 25-28 درجة مئوية / 35-65% رطوبة نسبية. The light grating sensor reads the encoder strip; failures cause position jumps, ghosting or homing errors. An OEM Nocai reader returns smooth feedback.

تحضير

خارج السلطة, افصل وتحقق من التأريض. Wear antistatic gloves and work in clean light. من خلال اللوحة, سائق أو FlexiPRINT, park the carriage mid-beam. Prepare an OEM Nocai grating sensor, small Phillips driver, ملاقيط, مناديل خالية من الوبر, ≥99% isopropyl alcohol and bracket photos. Do not touch the encoder strip or X-axis limit switch during setup.

قم بإزالة المستشعر القديم

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.

قم بتثبيت المستشعر الجديد

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. أعد توجيه الكابل بعيدًا عن حزام المحور X, carriage path and UV lamp, ثم قفل الموصل. 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. قم بتشغيل التنظيف التلقائي, print a nozzle test, step grid and alignment pattern; measure printed size against design. إذا بقي الانجراف, recenter the sensor, recheck the gap and cable. Stable readings complete the NC-UV0609MAX-II Light grating sensor replacement.

رعاية ما بعد الاستبدال

Wipe the encoder strip and sensor window with alcohol in one direction weekly, schedule strip cleaning about every 500 ساعات العمل, and monitor carriage noise for the first hour. قضبان الخدمة, ink station and cap top per manual, use only Nocai eco UV ink and original sensors, والحفاظ على 25-28 درجة مئوية / 35-65% رطوبة نسبية.
