ABSTRACT:
An automatic document job batching system for a copier with a recirculating document handler (RDH), with a document stacking tray into which a set of document sheets is loaded for recirculative precollation copying, and a separate (SADH) document loading entrance provided for semiautomatic non-precollation copying, utilizing a document gate for selectably directing documents to this tray or to be ejected from the RDH. All document jobs to be copied may be preloaded, and left unattended, for automatic sequential loading and copying, in a common stack, face down, as a batched plurality of intermixed documents and document set jobs interleaved with job slip sheets, in a job loading input adjacent the RDH which sequentially top feeds the documents into the SADH document entrance. Documents selected by slip sheet indica or otherwise to be precollation copied are automatically loaded into the RDH stacking tray one job batch at a time, or up to a preset document tray capacity, and then automatically recirculatively copied, and then automatically unloaded and ejected. RDH jobs with a number of documents exceeding the tray capacity are automatically divided, separately loaded, and separately recirculated, in sub-job sets of documents. Documents to be copied in a non-precollation copying mode are not loaded in the RDH tray and not recirculated, and automatically ejected. This reloading, selective copying, and ejecting is repeated in job batches until all preloaded documents have been copied.
