Abstract

When using computer forms feeding in a copier/duplicator, once imaging has begun and the form starts to move to the output side of the machine, two problems usually arise. First, an operator who wants to manually assist stacking into a catch tray must stop the copying process at the proper moment so that the first few panels are situated in the tray, and properly fold them. The operator can then restart the job. Second, if the system is designed with a self-stacking output tray, the form must be paused at the proper time to allow the first panel to settle in mid air so that it is vertical when it reaches the input throat of the tray.

First, an operator who wants to manually assist stacking into a catch tray must stop the copying process at the proper moment so that the first few panels are situated in the tray, and properly fold them. The operator can then restart the job. Second, if the system is designed with a self-stacking output tray, the form must be paused at the proper time to allow the first panel to settle in mid air so that it is vertical when it reaches the input throat of the tray.

The concept here is to program the controller software for the computer form web document feeder (preferably, one mode or function of an RDH) to make the CF web feed pause for a preset time period after theinitial feeding of the first few panels, at the point when the lead edge of the first a panel reaches the CF document restack tray, to assist the starting of stacking.

The software is designed with a built in pause, timed to occur when the lead edge of the web is just above a self-starting (initial fan-folding) CFF catch tray to allow for self-stacking. The pause, which is set for a few seconds, may occur when the lead edge advances a preset distanc...
