A digital printing or copying machine () is proposed for the one-sided or double-sided printing onto a substrate (), using at least one toner. The machine () includes at least one fixation device () for fixing the toner image on the substrate (). The fixation device () has at least one heating device () for melting the toner image, past which the substrate () can be taken. The machine () is distinguished by a guide device () for the free floating movement of the substrate () in the effective range of the heating device ().

Digital printing or copying machine

A digital printer or copier machine () is proposed for the single-sided or double-sided printing of a substrate (), with at least one fixing device () for fixing toner onto the substrate (), whereby the fixing device () has at least one heating device for fusing the toner. The machine has, in addition, at least one transport device (), in order to supply the substrate () to the heating device, to guide it past the heating device and/or to further transport it from the heating device, whereby the transport device () has at least one suction belt () that is provided with a number of through-passage openings () and can be impinged with a vacuum. The machine () is characterized in that the suction belt () is constructed as a mesh.

Fixing device transport for a digital printer or copier machine

A process or device for fusing toner on a carrier or a printing material, particularly a sheet-type printing material, preferably for a digital printer, wherein the printing material with the toner is irradiated with microwaves from at least one microwave conductor, which is heated to melt the toner and a toner is used which shows a sharp drop of the elastic modulus G&prime; from its hard state to its liquid state when heated. The ratio of the value of the elastic modulus G&prime; of the toner is the reference temperature value calculated from the initial temperature at the beginning of the glass transition of the toner plus 50&deg; C. to the value of the elastic modulus G&prime; at the initial temperature is <10 .

Process and device for warming up printing material and/or toner

A device and process for fixing a toner onto a substrate or a printed material, especially a sheet-shaped printed material, preferably for a digital printer, which is characterized in that the printed material that has the toner is irradiated with microwaves from at least one microwave emitter, and is heated to melt the toner, and that a toner is used which exhibits a sharp drop of the modulus of elasticity G&prime; from its solid to its liquid state when it is heated. Preferably, the ratio of the value of the modulus of elasticity G&prime; of the toner according to the invention at the reference temperature value, calculated from the starting temperature at the beginning of the glass transformation of the toner plus 50&deg; C., to the value of the modulus of elasticity G&prime; at the starting temperature itself is <10 .

Process and device for fixing toner onto a substrate or printed material
