  • Microwaves are used to fix the toner on the substrate known in principle. Because the absorption of microwave energy in the toner usually is at least one order of magnitude smaller than in the printing material, the is preferred Printing material is heated by the microwaves and the printing material in turn heats up the toner on it, up to a temperature at which the Connects toner with the substrate. As is known, when using Microwaves for fixing the toner characteristic values of the used Substrate, such as weight, moisture and composition, critical and take into account.

It can be achieved that a not too large one is chosen Resonator width in the substrate level and transverse to its transport direction very homogeneous intensity of the electric field is generated and thus the substrate or the toner carried by it over this width, and with uniform Feed of the substrate in the transport direction also over its length, is heated evenly.

  • the two middle resonators and the two outer resonators are connected together, each with respect to an axis of symmetry running between the two inner resonators have a symmetrical degree of filling. This is how half of the microwave sources can be or save magnetrons.
  • the scattered radiation that emerges from the openings of the resonators can also be by building a so-called choke structure and / or by using Reduce absorbent materials outside the resonator.

It is a relative speed (for example up to 100 cm / s) in such a way that also in a kinematic reversal, the fixing device relative to the stationary printing material could move or both components. Even a stationary fixation without any movement would be conceivable.

It turns out that the course of the intensity of the electric field E x in the direction of the x-axis, that is, in the direction of the width of the printing material, is almost rectangular, which means that this intensity is essentially constant over the width of the resonator 1 or is homogeneous. This brings about a heating of the printing material carrying the toner, which is proportional to the intensity distribution, namely the printing material is heated homogeneously over the X width of the resonator 1 during its transport in the transport direction 2.

  • resonators 1 are staggered one behind the other in a V-shaped formation arranged, the totality of the resonators 1 here as well Width of the conveyor belt 6 detected.
  • resonators 1 are staggered one after the other, likewise again in its entirety the entire width of the conveyor belt gathering.
  • the longitudinal edges of resonators 1 are successive each capture the next section of the width of the conveyor belt 6, drawn in alignment with each other. But it is for homogeneous heating of the toner-bearing substrate better if the working widths of the resonators 1 and the work areas they are overlapping overlap. On such an overlap area can preferably have a width of 1 mm to 30 mm, preferably from 1 mm to 10 mm.
  • the preferred number of resonators 1 then depends on the width of the individual resonator 1, the size of the overlap area and the width of the printing material or the conveyor belt 6. For example can according to the arrangement according to Fig.
  • resonators in two rows 4 resonators 1 can be arranged.
  • Each of these resonators 1 can cross to Transport direction 2 have a working width of 54 mm.
  • the two rows of resonators 1 can be a distance of 525 mm from each other in the transport direction 2 to have.
