Replace the Resin Cartridge with a Functional Unit

Since the bite valve on your current cartridge is swollen and physically obstructing the flow of resin, it must be replaced to resolve the Error 1.9.11 message.

1. Power off the Form 4L printer to ensure safety during the removal process.
2. Remove the faulty resin cartridge from the left-hand slot.
3. Inspect the underside of a new, functional resin cartridge to ensure the bite valve is not deformed or stiff.
4. Insert the new, functional cartridge into the left-hand resin slot, ensuring it is properly seated in the load cell area.
5. Power on the printer and navigate to the touchscreen interface to confirm that the 'Resin Flow' status has cleared and the printer is no longer reporting Error 1.9.11.
6. If the error persists, verify that the new cartridge is properly mixed by shaking it thoroughly before installation.
