Abstract

An arrangement for the lateral positioning of a recording medium (100) in a printer or photocopier comprises a scanning arrangement (S) for establishing the ACTUAL position of the recording medium and a motor-drivable roll arrangement consisting of a counter-roll (201) and a pressure roll (205) which can be pivoted onto and away from the counter-roll (201), between which rolls the recording medium is guided. Furthermore, an apparatus (E) is provided for the controllable adjusting of the pressing force at the feed roll (205) on the counter-roll (201) along its roll length, and a control arrangement (P) which registers the ACTUAL position of the recording medium (100) via the scanning arrangement (S) and adjusts the pressing force of the feed roll (205) via the said apparatus (E) as a function of a predeterminable REFERENCE position. The arrangement is used preferably in the fuser station of an electro-photographic printer for the controllable lateral positioning of the recording medium (100).
