How are ReadyToFeed, TrackClear and item events related?

[Bryan Clark]

Your application may begin or resume feeding whenever the TransportReadyToFeedState() event fires.

When the TransportReadyToFeedState() event fires and the previous state is TransportEnablingOptions:

• Your Ranger options have been enabled.
• The scanner is idle.

If any items are pocessed after a StartFeeding() call:

• The TransportTrackIsClear() event will fired after all items have completed processing and the scanner's is idle.
• Item events such as TransportNewItem() may be fired until the TransportTrackIsClear() event is fired.

If no items are pocessed after a StartFeeding() call:

• The TransportReadyToFeed() event will fire again with a previous state of TransportFeeding.
• The TransportTrackIsClear() event will not fire in this case, since no items were processed.
