Abstract (en)

[origin: DE10023919A1] Print sheets are aligned using rotation elements (25) which enable sheets (1) that are to be printed to be turned over. During the turning over process the leading edge (23) remains in its aligned position. In the transport plane a sensor pair (30) are arranged, preferably CCD row sensors, which are used to re-align the sheets after they have been turned over using the same side edge (24) as before the sheet was turned over around its middle axis. Independent claims are made for a device for alignment of print sheets, for a printer with a paper feed device including an alignment device, and for digital and electrographic printers with paper feed devices incorporating alignment devices.
