Zusammenfassung: | A deskewing and registering device for an electrophotographic printing machine. A single sensor determines the position and skew of a sheet in a paper path and generate signals indicative thereof. A pair of independently driven nips forward the sheet to a registration position in skew and at the proper time based on signals from a controller which interprets the position signals and generates the motor control signals. An additional single sensor can be used at the registration position to provide feedback for updating the control signals as rolls wear or different substrates having different coefficients of friction are used. |
