Abstract

Digital printers or copier machines (1) and processes to be performed using them, for fixing a toner image (5) transferred onto an image-carrier substrate (9), are proposed. One of the processes is characterized in that to fuse the toner particles, at least two electromagnetic radiation pulses are applied in a time-delayed manner onto the same area of the image-carrier substrate (9) and each one individual radiation pulse being in a range from 0.5 J/cm2 to 5 J/cm2.
