Abstract

Die Erfindung betrifft die Fixierung eines Farbauftrages (7) auf einem blattartigen und/oder endlosen Träger (6), insbesondere von Tonerpulver auf Kopierpapier und/oder Laserdruckpapier, wobei der Farbauftrag (7) erwärmt wird, um eine dauerhafte Verbindung mit dem Träger (6) und insbesondere eine Vernetzung des Toners zu erzielen. Erfindungsgemäß wird der Farbauftrag (7) mit Infrarotstrahlung bestrahlt, so daß der Farbauftrag (7) durch Absorption zumindest eines Teils der Infrarotstrahlung erwärmt und fixiert wird. Insbesondere wird als Strahlungsquelle der Infrarotstrahlung eine Infrarotlampe verwendet, die vorzugsweise bei Emissionstemperaturen von 2500 K oder höher betrieben wird.

Figure 00000001
The invention relates to fixing a color application (7) on a sheet-like and / or endless support (6), in particular toner powder on copy paper and / or laser printing paper, the color application (7) being heated in order to establish a permanent connection with the support (6 ) and in particular to achieve crosslinking of the toner. According to the invention, the paint application (7) is irradiated with infrared radiation, so that the paint application (7) is heated and fixed by absorption of at least part of the infrared radiation. In particular, an infrared lamp is used as the radiation source of the infrared radiation, which is preferably operated at emission temperatures of 2500 K or higher.
