Abstract
An apparatus for advancing a sheet. The apparatus includes a transport which has the sheet releasably secured thereto in one mode of operation, and, in another mode of operation reduces the frictional force between the sheet and the transport to facilitate relative movement therebetween. A controller, in communication with the transport, selects the mode of operation of the transport.
Claims6
A printing machine of the type having a sheet advancing to a transfer station for receiving a visible image from a recording medium, wherein the improvement includes:
- a transport for advancing the sheet to the transfer station, said transport having the sheet releasably secured thereto in a first mode of operation, and, in a second mode of operation, reducing the frictional force between the sheet and said transport to permit relative movement therebetween;
- and
- a controller, in communication with said transport, to select the mode of operation of said transport;
- and
- means for sensing the sheet advancing on said transport at selected positions, said controller being responsive to said sensing means for switching said transport between the first mode of operation and the second mode of operation.
