## Abstract

For a copier with a document handler ejecting original documents after copying into a document collection tray system, a plural mode document collecting system is provided for collecting and restacking different forms of documents, including both conventional sheet documents and computer form web being re-fanfolded, with a single tray movable between two different operative tray mounting positions in a substantially vertical track, with respective retentions at a first tray position adjacent the document output of the document handler for collecting conventional sheet documents, and a second tray position substantially below the first tray position for re-fanfolding computer form web. Also disclosed are stationary fanfold restacking assist members operative in the second tray position mounted intermediately of the first and second tray mounting positions and mutually adapted with the tray to allow the tray to be moved past. Also shown is an optional small document restacking guide pop-up surface optionally operative in the first tray mounting position for restacking small documents closer to the document output of the document handler.
