ABSTRACT:
An apparatus which advances a sheet through a transfer zone and into registration with information developed on a moving member. The sheet is advanced to a position wherein a leading portion thereof is within the transfer zone and a trailing portion thereof is immediately behind the transfer zone relative to the forward direction of movement of the moving member. The leading portion of the sheet is advanced through the transfer zone at a first velocity and the trailing portion of the sheet is advanced in a region immediately behind the transfer zone at a second velocity, which is greater than the first velocity, so as to create a buckle in the trailing portion of the sheet in the region. The buckle functions to eliminate relative velocity between the photoconductive belt and any portion of sheet within the transfer zone so as to substantially eliminate slip between the sheet and the photoconductive belt.
