The device allocation subsystem is in control. The user
only has access to the specific device by allocating it,
see allocate(1). The user runs along happily scanning.
The user is done and deallocates it, see deallocate(1).
The deallocation process (and in TX the allocation process)
runs the "device clean" program. This instructs the user
to remove any documents from the device and acknowledge they
have done so. The "device clean" program (or the device driver)
resets the device to defaults so no one accessing the device at
a later time can read out device parameters, such as scanning
density -- I'm hypothzing here -- at a later time.
