Double feed recovery and processing
A media separator module of a valuable media depository is selectively controlled to progressively and selectively activate drives for double feed media recovery processing when two items of media are detected within the media separator module.
1. A method, comprising:
(i) obtaining, by executable instructions that represent a double feed media recovery manager, the executable instructions execute on at least one processor of a media separator module, a double media reading from a pair of opposing ultrasonic sensors for media being urged from an entry point to an exit point through the media separator module;
(ii) stopping, by the double feed recovery manager, an advance drive that engages a top portion of the media from rotating in a first direction towards the exit point while continuing to rotate a retard drive that engages a bottom portion of the media in a second direction towards the entry point in response to the double media reading, wherein the retard drive opposes the advance drive, wherein (ii) further includes saving, by the double feed recovery manager, a pressure pinch setting of the media separator module noted when the advance drive is stopped in an non-transitory computer-readable medium;
(iii) obtaining, by the double feed recovery manager, a second reading from the ultrasonic sensors and when the double media reading remains as the second reading rotating the advance drive in the second direction;
(iv) acquiring, by the double feed recovery manager, a third reading from the ultrasonic sensors and when the double media reading remains as the third reading backing the media back to the entry point of the media separator module; and
continuing any current processing at (ii)-(iv), by the double feed recovery manager, for a configured period of time after a current reading from the ultrasonic sensors reports a single media reading;
wherein predefined time delays between the double media reading, the second reading, and the third reading control (i)-(iv).
2. The method of claim 1 , wherein (iii) further includes delaying, by the double feed recovery manager, the obtaining of the second reading for a configured period of elapsed time.
3. The method of claim 1 , wherein (iii) further includes rotating, by the double feed recovery manager, the advance drive in the second direction for a configured distance when the double media reading remains.
4. The method of claim 1 , wherein (iii) further includes rotating, by the double feed recovery manager, the advance drive in the first direction to separate the media into a top item and a bottom item with the top item urged towards the exit point and the bottom item urged towards the entry point when the second reading is a single media reading.
5. The method of claim 1 , wherein (iv) further includes rotating, by the double feed recovery manager, the advance drive in the first direction to separate the media into a top item and a bottom item with the top item urged towards the exit point and the bottom item urged towards the entry point when the third reading is a single media reading.
6. The method of claim 1 , wherein continuing any current processing further includes restoring, by the double feed recovery manager, the saved pressure pinch within the media separator module from the non-transitory computer-readable medium and restarting the media separator module after the configured period of time.
