I have an issue in the colonoscope fujifilm model EC-530WL3.
If I want To supply air, I stop the hole in the center of the Air/water button with a finger, but the air does not exit from the air nozzle at the distal end.
But, when I removed the air/water valve and closed the hole by finger, the air exit from the air nozzle at the distal end. But if I put the air/water valve and stop the hole of the center of the air/water button with a finger, the air does not exit from the nozzle.
So, please help me. What can i do? RE: Fujifilm - Standard Colonoscopes
