NC-UV0406-VI grating strip replacement

恰當的 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 解析度, FlexiPRINT 迷你伺服器 22 諾凱版, 143瓦, AC 220/110V, and eco UV ink; it works best at 25–28°C / 35–65% RH . The grating strip acts as the carriage ruler; a dirty, scratched, loose, or broken strip causes ghosting, wrong margins, homing faults, or carriage crashes. Replacing it with a matched Nocai strip returns stable positioning.

準備

Power off and unplug the printer. 戴防靜電手套. 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, 鑷子, 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.

Removing the Old Strip

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, scratches, 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.

Installing the New Strip

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.
