恰當的 NC-UV0406-VI Scraper replacement​ keeps the Epson I1600-U1 nozzle plates clean and prevents banding, missing dots, and ink buildup. The NC-UV0406-VI is an A2 desktop UV printer with two I1600-U1 heads, 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 runs best at 25–28°C / 35–65% RH. The scraper removes residual UV ink during maintenance cycles; UV ink chemistry often requires more frequent wiper service than aqueous ink.

準備

Power off and unplug the printer; verify grounding. Wear nitrile gloves. Open the transparent cover and move the carriage to the maintenance position through FlexiPRINT or the control panel. Prepare a 2.0 mm hex/Phillips set, lint-free wipes, genuine Nocai UV cleaning solution, and a new scraper matched to NC-UV0406-VI/I1600. Inspect the cap station, wiper holder, and ink tube routing before disassembly.

Removing the Old Scraper

Release the wiper holder screw or clip, then slide out the old blade. Check for hardened rubber, cracks, ink caking, or edge deformation. Worn wipers can scratch the nozzle plate, so replace immediately if damaged. Photograph the holder angle and blade orientation. Dispose of the old blade safely; UV ink residue is sticky and may stain surfaces.

Installing the New Scraper

Seat the new OEM wiper in the holder with the cleaning edge parallel to the printhead nozzle line. Hand-tighten the screw, then torque lightly per Nocai manual—avoid over-pressure that could bend the blade or touch nozzles. Clean the cap top and surrounding area with UV cleaning solution. Confirm the wiper travels smoothly across both heads without obstruction.

Testing and Care

Power on, run Auto Cleaning in FlexiPRINT, then print a nozzle test. All channels should fire evenly with no streaks. Inspect the wiper daily; replace every 1–3 months under UV ink use, sooner for heavy production. When the test strip is clean, the NC-UV0406-VI Scraper replacement​ is complete and the printer is ready for production.
