ちゃんとした NC-UV0609MAX-Ⅱ grating strip replacement​ restores X-axis positioning on this 600×900 mm industrial UV printer. The machine prints 0–180 mm height, uses Epson 13200-U1 white, 13200-U1HD color and 11600-U1 varnish, runs CMYK+LC+LM+LK+LIK+W+V at 720×600/900/1200 dpi, FlexiPRINT ミニサーバー 22, 470W, AC220/110V, negative-pressure eco UV ink, 25–28℃ / 35–65%相対湿度. The encoder strip works as the carriage ruler; 傷, インク, dust or misalignment cause ghosting, homing errors or carriage faults. Replacing it with a genuine Nocai strip returns stable readings.

準備

Power off, unplug and verify grounding. 静電気防止手袋を着用する. Move the carriage to the middle of the beam through the panel, driver or FlexiPRINT. Prepare an OEM Nocai grating strip, screwdriver, ピンセット, 糸くずの出ないワイプ, ≥99% isopropyl alcohol and photos of brackets. Do not touch the sensor or X-axis limit switch during preparation.

Remove the old strip

Loosen the top or side cover screws per the manual, then release the strip brackets. Slide the old encoder strip out of the sensor slot slowly to avoid bending it. Inspect for scratches, インクミスト, grease and slack tension. If only dust or ink causes errors, clean with alcohol in one direction and retest before replacement.

Install the new strip

Fix one end of the new OEM strip, route it straight through the encoder sensor slot without twisting, then secure the other end. Adjust upper and lower screws so the strip stays centered in the sensor gap; the carriage must move without scraping the strip. Keep the strip parallel to the beam and away from printheads, cables and the UV lamp area.

Homing and accuracy test

Power on and move the carriage left or right; the control panel should show positive X-axis values that increase smoothly without jumps. 自動クリーニングを実行する, then print a nozzle test and an alignment grid. Measure printed size against design size. If drift remains, recenter the strip and clean the sensor slot. When readings are stable, the NC-UV0609MAX-II grating strip replacement​ is complete.

Post-replacement care

Clean the encoder strip with alcohol in one direction weekly, keep the sensor slot dust-free, and avoid touching the scale with bare hands. Service rails, ink station and suction platform per the manual, use only Nocai eco UV ink and original parts, 25 ～ 28°C を維持します / 35–65%相対湿度.
