Resin Sensor Empty - No Resin Detected in Tank
Quick Answer
Error code 110 on your Formlabs Professional Resin 3D Printers means: Resin Sensor Empty - No Resin Detected in Tank. This is usually fixable — see the step-by-step guide below.
Likely Causes
  1. Resin tank is genuinely empty and needs refilling
  2. Resin cartridge dispenser valve is stuck and not releasing resin into the tank
  3. Resin level sensor is dirty or coated with partially cured resin
  4. Resin is too viscous at the current temperature for the sensor to read properly
How to Fix It
1
Check the resin level visually in the tank to confirm it is low
2
If a cartridge is installed, verify the bite valve is open and the cartridge is properly seated
3
Gently press down on the cartridge to ensure it is fully inserted into the dispenser mechanism
4
Clean the resin level sensor area with isopropyl alcohol if resin residue is visible
5
If using an open-mode resin, manually pour resin to the fill line on the tank
