J392472-03 PCB FOR HS-1800

J392472-03 FOR HS-1800 **Upgrading the Noritsu S-4 to HS-1800 Standalone Operation** Converting a Noritsu S-4 to an HS-1800 configuration gives an existing scanner a new role as an independent film-scanning workstation, without relying on the original minilab printer. The conversion involves compatible hardware and software. Conversion kits are offered with **J391472 and J391203 circuit boards**, but the correct board revisions and required components must be checked against the individual scanner before installation. A professional upgrade should include: 1. **Inspection and backup:** Check the scanner, film carriers, optics and electronics, and save existing settings and calibration data where accessible. 2. **Hardware conversion:** Install the compatible conversion components according to the relevant service documentation. 3. **Computer and software setup:** Configure a suitable PC with compatible scanner software, drivers and properly licensed scanning software. 4. **Adjustment and calibration:** Complete the required setup procedures and check focus, film transport and image consistency. 5. **Final testing:** Scan sample films using each supplied carrier to verify reliable operation and image quality. The aim is to extend the useful life of the scanner through a properly configured, tested conversion. The final result depends on the condition of the original scanner as well as the quality of the installation. **Contact KEI International with your S-4 serial number, board photographs and film-carrier details to discuss the appropriate upgrade.**
