There are various problems in the recirculation of original documents, including restacking. One of the problems is restacking of documents with curled or folded-up edges, such as documents that have been previously folded for insertion into a letter envelope. The latter documents tend to have a raised rrwingrr set or configuration, as shown by the top sheet in the Figure. Such raised edges on the documents can cause uneven restacking, with one edge of the document tending to lie against one of the side guides of the tray. Such documents tend to climb up one of the side guides, due to fluffing by the document feeder air knife, for exainple. This tendency to climb the edge guide (with consequent gross lateral misalignment and misfeeding) is greatly aggravated by an in-tray lateral registration system urging such documents toward that side guide, as shown for example in the Silverberg U. S. Patent N0.4-381-893. A simple rotary flapper type lateral feeder/jogger in the tray bottom is one species of said 4,381,893 system, and is shown in the accompanying drawing. Accordingly, an anti-climbing, saw-toothed, wall configuration is shown.
