If physical hardware checks have been ruled out, a firmware reinstallation can resolve persistent software-related reporting errors that cause the printer to misinterpret flow rates.
- Navigate to the Formlabs support website and download the latest firmware package for the Form 4L.
- Connect your printer to your computer via USB or ensure it is on the same local network.
- Use PreForm software to manually trigger a firmware update/reinstall, even if the printer reports that it is currently up to date.
- Allow the printer to complete the full reboot cycle after the installation is finished.
- Attempt a test print to verify if the 1.9.11 error persists during the automated fill process.
