Apropriado NC-UV0609PEIII-II butterfly filter replacement​ is required when printouts show banding, nozzle dropouts, or the ink pressure becomes unstable—symptoms that typically indicate a clogged butterfly filter in the ink supply path. Butterfly ink filters are compact, flat-bodied filters widely used in UV printer ink systems to remove particles and debris, protect the printhead from clogging, and stabilize ink flow. Most manufacturers recommend replacing printer ink filters every 3–6 months depending on ink type and usage frequency. Replacing the butterfly filter restores clean ink delivery and protects the printhead. Because the procedure involves the ink circuit, it should be performed carefully and, ideally, under the guidance of your local NOCAI distributor.

Preparação

Desligue a impressora e desconecte o cabo de alimentação. Use luvas de nitrilo. Prepare absorbent paper and a small waste container. Você vai precisar: a new genuine butterfly filter matched to NC-UV0609PEIII-II, alicate de bico fino, a camera or smartphone to photograph the current installation, and the NC-UV0609PEIII-II user manual. Before ordering the replacement, confirm the filter model, micron rating, connector style, tube size, flow direction, and installation position against the old filter label.

Removing the Old Filter

Locate the butterfly filter in the ink supply path—commonly installed before the printhead or between the sub-tank and ink outlet. Photograph the current orientation and tube routing. Using needle-nose pliers, gently loosen the fittings and disconnect the ink tubes. Remove the old filter. Note that butterfly filters typically have in/out ports and are not directional, but always verify against your recorded photos.

Installing the New Filter

Inspect the new filter to ensure the model and micron rating match the old one. Connect the ink tubes to the new filter using the same port configuration captured in your photos. Tighten the fittings with pliers—secure, but do not over-torque to avoid cracking the compact body. Route the tubes neatly along the original path.

Purging and Leak Check

Reconecte a alimentação e ligue a impressora. Enter the maintenance menu and run the ink supply / purging function to remove air from the new filter and lines. Watch for steady ink flow without bubbles. Inspect all fittings for leaks. Once purging is complete, run a nozzle check—all channels should fire fully. Print a test pattern to confirm stable ink density. When ink flow is clean and prints are defect-free, o NC-UV0609PEIII-II​ está pronto para produção.

Cuidados pós-substituição

Check the new filter and fittings for leaks during the first hour of operation. Schedule the next filter replacement in 3–6 months based on ink consumption. Record the replacement date and filter model for maintenance tracking. Note that the one-year maintenance warranty excludes ink-related parts, and using non-NOCAI ink may affect after-sales support.
