In office printers hot roller fusing is favored, whereas non-contact fixing methods are used especially in web printing. The aim of this study was to find out whether there are differences in quality-forming characteristics between contact and non-contact fixing.Unfused print areas were fixed with a detached hot roller fuser, IR radiation or with a hybrid of these two. The fixing energy was varied with the temperature and fixing time. In addition to basic quality measurements, the micro-scale quality was measured with a multigeometrical optical testing device, which allows different quality variables to be measured from exactly the same spot. Text quality was measured with a scanner-based system. This paper presents the data and discusses the results from the viewpoint of the mechanisms behind fixing quality.
