7.2.2 Checking of the cap leak

2. Turn ON the power supply, and make the status capped.
3. Remove the top edge of the tube between the suction pump and the waste tank, and connect the syringe.
4. Pull out the connected syringe slowly. As a reference, pull out about one scale per one second.
(If you pull out it swiftly, you cannot check leakage.)
 Do not push the syringe. It may push foreign object into the nozzle, and it may cause nozzle defect.
 Criteria for judgment
OK: If you feel a good response when pulling the syringe (You can feel that you are pulled back.)
The cap is OK. Check other supply system.
NG: If you do not feel a good response when pulling the syringe (You can pull easily.)
Cap leakage occurs. Check the cap and the cap position.
