Note 1:  Continuous Polling (Station Mode)
This feature allows you to store or add documents into a polled file in memory. 
To enable the Continuous Polling feature set Function Parameter No. 003 to “2:Station”. 
The last Program Key will be assigned with the “Store 4 Poll” Key name automatically 
and cannot be changed. 
To prepare the document(s) to be polled, simply place the document(s) on the ADF or Platen 
and then press the Program Key to store or add the document(s) into a polled file.
(Note: If a regular polled file is stored in memory, the Program Key for Continuous Polling will 
not be accepted.)
