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 immediately ahead of the transfer zone relative to the forward direction of movement of the moving member and a trailing portion thereof is within the transfer zone. The leading portion of the sheet forms a presentation angle of 7-10 degrees with the horizontal. The trailing portion of the sheet is advanced through the transfer zone at a first velocity and the leading edge of the sheet is advanced in a region immediately ahead of the transfer zone at a second velocity, which is less than the first velocity, so as to create a buckle in the leading portion of the sheet positioned immediately ahead of the transfer zone relative to the forward direction of movement of the moving member. 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.

Sheet transport system with improved registration

An apparatus is described which advances a sheet in a predetermined path through a transfer zone and into registration with information developed on a moving member. The apparatus charges the sheet to transfer the information from the moving member to the sheet. The apparatus includes a mechanism to maintain the charge on the sheet during advancement thereof.

Transfer mechanism for a sheet transport system

A sheet transport system having a sheet gripper which includes at least one resilient member used to bias an upper gripping portion toward a lower gripping portion so as to releasably secure the leading edge of a sheet therebetween. The resilient member includes a stop which functions to register the sheet within the sheet gripper.
