Method and apparatus for preventing dust, which developes in document handling machines, from accumulating in the orifices of associated ink jet printers and clogging them, includes disrupting the path of dust laden air to prevent it from flowing near the orifices where dust would be deposited. In a preferred embodiment, a counterflow of air from a fan is directed against the dust laden air to disrupt its flow and cause the dust to be carried away from the orifices.

Method and apparatus for eliminating dust from ink jet printers

A cam operated document stop in an item sorter provides positive action to halt the passage of a document or other item, from a flow of documents in a mainstream pathway, when it arrives in an inspection station. The document is stopped in an open receptacle area for inspection and then released for return to the mainstream pathway. Stoppage is effected by rotation of cam members which position a stop arm to stop the flow of the document. After the document has been inspected and corrected, the stop arm is repositioned to release the document into the mainstream flow. After a suitable delay to allow the document to clear the receptacle area, the cam members rotate the stop arm into position to stop the next document.

Cam operated document stop for high speed item sorter

An item/document hold and view station for use with high speed item sorting apparatus wherein a diverter is provided for diverting selected items out of the mainstream item pathway and into an open ended receptacle area for visual viewing by an operator and including a pair of eccentric cam members interconnected by a flexible member is operable to move the item out of the viewing station and back into the mainstream item pathway once the item has been altered, changed, corrected or otherwise handled by the operator without blocking or obscuring the data from the operator's view.
