Details
When there is contact between the armature edge
area of the flapper solenoid and the collar
projection area, the rotation of the holding gate
can be controlled ON/OFF. But the armature edge
area and collar contact does not operated normally
because of uneven parts. As a result, ADU jams
can occur.
Countermeasure
To prevent the contact of the armature with the
collar, they have been changed from June at the
factory. (Refer to the above list.)
