Q1: Which coding printer models is the MB-PC1945 55U nozzle compatible with?
A1: It is primarily compatible with KBA-Metronic and Rottweil Continuous Inkjet (CIJ) printers. Before purchasing, we recommend verifying that the part number on your existing printhead assembly is MB-PC1945.
Q2: What does "55U" mean? How does it differ from 60U or 70U?
A2: "55U" indicates a nozzle orifice diameter of 55 microns.
55U: Produces smaller ink droplets; suitable for precision printing requiring high resolution and micro-printing (e.g., electronic components, pharmaceutical packaging).
60U/70U: Features larger orifice diameters and produces coarser droplets; suitable for standard font printing on items like food products and cardboard boxes.
Q3: What material is this nozzle made of?
A3: The nozzle typically consists of a stainless steel body with an embedded synthetic gemstone insert (such as ruby or sapphire). The gemstone insert ensures the orifice remains undeformed over time, resists wear and chemical corrosion, and maintains ink stream stability.
Q4: Why does the ink stream appear skewed or fail to align with the gutter after installing a new nozzle?
A4: This is usually caused by tiny impurities or air bubbles inside the nozzle, or by a misalignment during installation. First, run the printhead cleaning procedure (using the designated cleaning fluid). If the stream remains skewed after cleaning, you may need to make fine adjustments to the physical angle of the nozzle base to ensure the ink stream enters the gutter precisely.
Q5: How can I extend the service life of the 55U nozzle?
A5: Regular maintenance: Always perform an automatic cleaning cycle before shutting down the machine to prevent ink from drying and clogging the tiny 55-micron orifice. Use high-quality ink: Avoid using low-quality or expired non-original inks, as particles that are too large can cause nozzle wear or permanent clogging.
Q6: What are the advantages of Kingsfang parts?
A6: They are developed in-house and fully compatible with the machine's functions. A professional team provides support ranging from troubleshooting to installation and usage. Shipping is extremely fast, with tracking information available within 1–3 days. They offer a comprehensive range of parts—including hard-to-find items—and are highly popular among sellers.
Q7: Can I test the parts or visit the factory?
