Abstract: A printer or copier has an optical character generator for reproducing raster image data in grey-scale displays. Integrated light sources in the form of LEDs arranged in arrays are aligned to form a print line. A control IC is provided for each LED array. Groups of the control ICs are formed in which information is shifted for the switch on time of all LEDs of a group starting with the first control IC to the next IC. The ICs are connected together by bonding. A ramp circuit is provided to prevent current surges when the LEDs are switched on. A flat unit that extends along the character generator is used to transmit information and power to the control ICs. Busbars ensure that power is provided to the LEDs.

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).
