Abstract

A digital printing or copying machine (1), and a process which can be carried out with it, for one-sided or double-sided printing of a substrate (5) using at least one toner are proposed. The machine (1) includes at least one fixing device (3) for fixing of a toner image (29) on the substrate (5), having at least one heater (21, 23) for melting the toner image (29), past which the substrate (5) can be guided by a transport device (11) which has one or more transport elements (29, 63 to 71). The machine (1) is characterized in that the heater (21, 23) has at least two melt areas (31, 33, 43 to 47) on the substrate (5) which viewed in the substrate transport direction (15) are arranged in succession and laterally offset to one another.
