Правильный NC-UV0406-VI Nozzle plate replacement​ restores uniform jetting on this A2 desktop UV printer. В NC-UV0406-VI используются две головки Epson I1600-U1., prints 400×600 mm with 0–180 mm height, supports CMYK+W or CMYK+W+V up to 1200 точки на дюйм, runs FlexiPRINT MiniServer 22 Нокайское издание, and uses eco UV ink at 143W, AC 220/110V, 25–28°С / 35–65% относительной влажности . The I1600 nozzle plate has 1600 nozzles in 4 rows; царапины, cured ink, or persistent clogs reduce quality. Replace the plate or the whole head with a genuine OEM part.

Подготовка

Выключите и отключите принтер от сети.; wear antistatic gloves and a wrist strap. Open the transparent cover and move the carriage to the maintenance position. Prepare a precision screwdriver set, пинцеты, безворсовые салфетки, ≥99% isopropyl alcohol, Nocai УФ-очиститель., and a new OEM I1600 nozzle plate or complete I1600-U1 head specified for NC-UV0406-VI. Photograph cable routing and plate orientation before disassembly.

If the plate is a separate service part, unscrew the retaining screws and lift it straight off; never touch the nozzle surface. If the plate is integrated with the head, disconnect ink tubes/dampers first, then unplug the head flat cable by the connector shell, remove head screws, and lift the assembly. Inspect for ink crust, bent pins, or physical damage before fitting the replacement.

Installing the New Plate or Head

Clean the mounting face with isopropyl alcohol and let it dry. Align the new plate with locating pins; if fitting a complete head, seat it squarely in the carriage and tighten screws evenly—service manuals for separate plates often specify about 0.3–0.4 N·m, while integrated-head torque must follow the NC-UV0406-VI manual. Reconnect ink lines and the flat cable flat, not skewed; keep ink away from connectors

Priming and Nozzle Test

Включение питания, run manual inking to purge air, then Auto Cleaning in FlexiPRINT. Распечатайте тест дюз; all CMYK+W/V channels should fire without gaps. Set head-to-media distance around 2–3 mm for testing, verify alignment, and reprint if needed. When output is even and streak-free, the NC-UV0406-VI Nozzle plate replacement​ is complete and the printer is ready for production.

Уход после замены

Run daily nozzle checks, keep white ink circulating, and maintain 25–28°C / 35–65% относительной влажности. Use only Nocai original ink, cleaning fluid, and OEM heads. Replace wiper and cap parts on schedule to protect the new plate.
