What to do if there is no powder feed from Gema Control Unit OptiHopper?
- A
  Anna ShermanAug 19, 2025
  If there is no powder feed from the Gema Control Unit OptiHopper, it might be due to several reasons. First, check if the OptiHopper is empty and refill powder manually. Second, powder accumulation on the optional level sensor can be a cause, so clean the sensor, readjust its sensitivity, and check the fluidizing, increasing the fluidizing air pressure if necessary. Also, the optional compressed air pulse cleaning might not be working; check its function at the corresponding output and replace it if needed. The level sensor or cable could be defective, in this case replace them.
