When ejecting into the sub pocket (only for two-pocket models)
When documents are sorted into the two ejection pockets, a document is fed backward to the
pocket switching position and then ejected into a pocket if the ejection pocket is required to be
switched and the document is long. In that case, the processing slows down.
