Apropriado NC-UV0406-VI Nozzle line replacement​ restores stable ink delivery to the dual Epson I1600-U1 printheads. The NC-UV0406-VI is an A2 desktop UV printer with 400×600 mm flatbed, 0–180 mm de altura, CMYK+W ou CMYK+W+V até 1200 dpi, Miniservidor FlexiPRINT 22 Edição Nocai, 143C, CA 220/110 V, and eco UV ink; it works best at 25–28°C / 35–65% UR . When nozzle lines are aged, kinked, leaking, or air-filled, prints show banding, missing channels, or uneven color. Replacing tubes with genuine Nocai parts and bleeding air returns consistent jetting.

Preparação

Desligue e desconecte a impressora; wear nitrile gloves. Open the cover and move the carriage to the maintenance position. Prepare replacement UV ink lines matched to NC-UV0406-VI, braçadeiras de mangueira, pinça, lenços sem fiapos, Nocai UV cleaning solution, and a small syringe if priming is needed. Photograph each tube route, color order, and connector type before disassembly. Check dampers, ink sac, and cap station for leaks.

Removing the Old Nozzle Lines

Clamp the supply tube near the ink tank to stop flow. Disconnect the old line from the ink tank, damper or ink sac, and printhead manifold in that order. Avoid pulling the printhead flat cable. Remove kinked or discolored sections, and dispose of UV-ink-contaminated tubing safely. Inspect barbs and quick connectors; replace worn clips to prevent future air intake.

Installing the New Lines

Fit new OEM tubes by color, pushing fully onto each barb or lock fitting. Route without sharp bends, away from the carriage path, UV lamp, and cable harness. Reconnect the damper or ink sac, then the printhead side. Keep white-ink lines separate and shake white ink before filling to reduce sediment. Confirm all fittings are seated before powering on.

Air Bleeding and Nozzle Test

Ligar, run manual inking to purge air from each line, then Auto Cleaning in FlexiPRINT. Print a nozzle test for all CMYK+W/V channels; repeat cleaning only if gaps remain. Set head-to-media distance around 2–3 mm for verification, check alignment, and reprint if needed. When every channel fires evenly, the NC-UV0406-VI Nozzle line replacement​ is complete and the printer is ready for production.
