(2) Machine-Based Factors
When a component has no problem, check the main body of the ma-
chine.
A failure can be tracked by checking if it occurs on a specific vacuum
nozzle or feeder slot No.
(2-1) When a failure occurs on a specific vacuum nozzle, check the
following items concerning the pertinent vacuum nozzle.
• Check if the nozzle is abnormal.
• Check if the vacuum line is abnormal.
• Check if the vacuum ON/OFF valve is abnormal.
When a factory is dusty or a lot of components packaged in paper tapes
are used, the vacuum nozzles and their filters get dirty easily. There-
fore, it becomes important to clean the vacuum nozzles and filters pe-
riodically.
Refer to "(1) Frequent Failures on Specific Vacuum Nozzle" in "5.2.2"

new components after program change operation because
it is prepared for the previous components.
