Roland 700 (706) machine has two coating units, both coating units not running

Dear sir, our roland 700 (706) machine has two coating unit. Both coat units not run. Coat level too low

 

can anybody help me?

 

if the coating supply and return pumps are working normally and you have the coating or UV in chamber blades and still have the level too low then clean the sensor and adjust it if needed.

 

chemical available in the tray

 

clean the detectors and adjust them accordingly
