AL-1457 (serv.man27). Installing the software - Sharp Copying Equipment User Guide / Operation Manual. Page 20

The settings for the Windows Event Manager for 
the SHARP AL-xxxx (where xxxx is the model 
name of your unit) device allow the user to take 
advantage of the Sharp Button Manager to take 
control of events from Windows and send 
scanned images to any application that can be 
selected in Button Manager.
This can be done with the Windows OS showing 
the Event Manager selection dialog or directly 
into a selected application if the Button Manager 
is the only allowed handler for device events 
from the SHARP AL-xxxx (where xxxx is the 
model name of your unit).
This is done by changing the Windows device 
settings for the AL-xxxx (where xxxx is the model 
name of your unit) in the Scanner and Camera 
device settings in the Control Panel.

Windows Platforms provide a mechanism for software to handle external events for 
a scanner device like the SHARP AL-xxxx (where xxxx is the model name of your 
unit) series products. This mechanism is controlled by the device manager on a 
device basis. Applications that can handle events from a scanner/camera device 
register with the Windows Event Manager and shown as available in the registered 
applications. The path an event takes to get to the user's selected application 
depends upon the event settings for the device.

This is the Control Panel
Properties dialog for "Scanners and
Cameras".
