ABSTRACT:
Different copy elements, such as letterheads, unprinted sheets, envelopes or the like can be fed from different supply stacks (2, 3; 3a, 3b, 3c) by individual separating rollers (7, 8) which frictionally engage the uppermost of the copy elements of the respective stacks. The copy elements are fed into the gap between a platen (10) of the printer, and then deposited on an output stack. The selection of the copy element from the specific stack (2, 3 for example) is obtained by different angles of rotation of the platen, in reverse--that is, counter to the sheet feeding direction--to thereby, selectively, engage different ratchets and ratchet wheels of a coupling connected to the respective separating rollers which feed the copy elements from the respective stacks.
