A guiding device for a freshly printed sheet has a sheet-guiding surface, which is located at a distance from an imaginary conveying surface. The sheet has a leading edge, which sweeps over the imaginary conveying surface along a sheet transport direction perpendicular to the leading edge of the sheet. The sheet-guiding surface is formed on a guide-plate arrangement and has blast-air openings. The sheet-guiding surface includes blast-air nozzles of a first nozzle configuration and of at least a second nozzle configuration. The blast-air nozzles of the first nozzle configuration produce air-jets that sweep over the sheets and are aligned with respect to the sheet transport direction. The blast-air nozzles of the second nozzle configuration produce rotational flows sweeping over the sheets.
