ABSTRACT:
In a copier with a sorter with plural bins for collating the copier output copies, and an alternate copy output tray (which may be separated or comprise one bin of the sorter) and a document feeder for sequentially feeding one or more document sheets placed therein to the copier to be copied, and a copy count control for selecting one or more copies to be made by the copier and copy sheet output switching for switching the copy output to the sorter for collation or to the alternate copy output tray for stacking; an automatic document sheet sensing system provides signals indicative of whether or not more than one document sheet had been placed into the document feeder by sensing the feeding of one (the first) document sheet by the document feeder to be copied and the presence or absence of at least one additional document sheet in the document feeder, and a copier control responsive to either a signal indicative of only one document sheet or to the selecting of only one copy in the copy count control to automatically control the copy sheet output switching to direct all of the copy output to the alternate copy output tray, this control also being responsive to the combination of signals indicative of more than one document sheet and the selecting of more than one copy to automatically direct the copy output to the plural bins of the sorter, whereby the copy output may be individually fed to a number of the plural bins of the sorter corresponding to the copy count. The document sheet sensing system may comprise two sensors spaced along the document feeding path.
