Правильный NC-UV0406-VI grating strip replacement​ restores accurate X-axis positioning for the dual Epson I1600-U1 printheads. The NC-UV0406-VI is an A2 desktop UV printer with 400×600 mm flatbed, 0–180 mm height, CMYK+W or CMYK+W+V up to 1200 точки на дюйм, Мини-сервер FlexiPRINT 22 Нокайское издание, 143Вт, AC 220/110V, and eco UV ink; it works best at 25–28°C / 35–65% относительной влажности . The grating strip acts as the carriage ruler; a dirty, поцарапанный, loose, or broken strip causes ghosting, wrong margins, homing faults, or carriage crashes. Replacing it with a matched Nocai strip returns stable positioning.

Подготовка

Выключите и отключите принтер от сети.. Наденьте антистатические перчатки.. Move the carriage to the middle of the beam so the strip is relaxed. Open the transparent cover and loosen the upper/side screws as instructed in the Nocai manual. Prepare lint-free wipes, ≥99% isopropyl alcohol, a Phillips driver, пинцеты, and a new OEM grating strip specified for NC-UV0406-VI. Photograph the strip ends, card brackets, reader position, and X-axis limit switch before removal.

Удаление старой полосы

Do not touch the engraved scale with fingers. Loosen the strip-card screws or end brackets gently. Slide the old strip out of the reader sensor slot first, then release both end fixtures. Inspect for ink mist, царапины, grease, or slack tension. If only dust causes reading errors, clean with alcohol and retest; replace only when damage remains. Avoid pulling the reader sensor or X-axis limit switch during removal.

Установка новой полосы

Fit one fixed end of the new strip, then route it straight through the reader slot without twisting. Keep the strip centered in the sensor gap, apply even tension per manual, and secure the spring or card bracket at the other end. The strip should be parallel to the carriage beam and not contact the printheads, cables, or UV lamp area. Recheck that numbers or reference marks face the correct direction if the OEM part is directional.

Homing and Accuracy Test

Power on and run the homing sequence; the carriage should move to the origin and return correct X-axis readings. In FlexiPRINT, print an alignment chart and a small grid pattern; measure printed size against the design size. If margins drift or ghosting remains, recheck strip centering, tension, and reader cleanliness. When X-axis readings are stable and output size matches, the NC-UV0406-VI grating strip replacement​ is complete and the printer is ready for production.
