In a xerographic copier configuration having a semiautomatic document feed (SADF) input, such as shown in U.S. Patent 3,910,570, there exists relative motion between the original document and the document drive belt when the document is started and stopped. This relative motion causes the paper to become charged with static electricity. The charge of the paper causes a repelling force between the sheets which are stacked in the exit pocket of the SADF. This repelling force prevents the sheets from settling to the bottom of the exit pocket. Consequently, subsequent incoming sheets may strike the end of a sheet which is in the exit pocket and has not properly settled and stacked.
