Definitions

  • the invention relates to a digital printing or copying machine for one-sided or double-sided printing of a substrate using at least a toner according to the preamble of claim 1.
  • the contacting and non-contacting melting processes use, for example, toners whose glass transition temperature (T G ) is in a range from 45 ° C. to 75 ° C.
  • the glass transition temperature at which the toner begins to soften, starting from the solid state can be influenced by the choice of raw materials and by the addition of certain additives to the toner.
  • a fixing device for the toner having at least one heating device, both the toner and the substrate itself are heated.
  • the surface temperature of the substrate must be in the range of the glass transition temperature of the toner or above.
  • the toner already reaches or exceeds the glass transition temperature (T G ) in the area of the heating device.
  • Printing and copying machines are known in which the substrate is double-sided is printed or coated, whereby for printing the front and Back either one and the same imaging and transmission device and heater or separate imaging and Transmission device and heating device can be used.
  • the substrate is often with the help of a conveyor belt on which the substrate rests on the at least one imaging and transfer device and passed the associated heating device. Doing so first transfer a first toner image to and onto a first substrate side fixed. A second toner image is then applied to the second substrate side transferred and fixed. When the second toner image is melted there is therefore first substrate side with the already fixed first toner image thereon on the conveyor belt.
  • the disadvantage here is that during melting of the second toner image, the first toner image can heat up so far that it becomes soft and tends to stick to the conveyor belt. This can be too cause several unwanted effects: sticking it can cause a substrate jam during the transfer of the substrate from the conveyor belt a subsequent part of the machine. Furthermore, the appearance of the Toner image in the areas where it sticks to the conveyor belt change. This leads to problems with the image quality, for example, that Toner image has an uneven gloss.

  • the printing or Copier is characterized by a guide device for free floating displacement of the substrate in the effective range of the heating device out.
  • “Floating” means that the substrate has no contact another surface, for example a conveyor belt, a support plate or the like. If the substrate is printed on both sides, it points on one side (underside) of a first toner image that is already on the substrate is fixed when one transferred to the other, second side of the substrate (upper side) second toner image is melted by means of the heating device. It can the first toner image is heated until it tends to stick / stick, when it comes into contact with a surface.
  • the substrate during the melting process of the second toner image at least as long as it is suspended so that the first toner image is so far cooled down, that it no longer tends to stick to surfaces, one can Damage or deterioration in the quality of the first toner image be excluded. It can therefore have a consistent image quality and one Uniform gloss of the toner images on the front and back of the substrate can be guaranteed.
  • the front of the substrate - depending on the view - both can form the top as well as the bottom, that is, the first toner image can be on the front or back of the substrate. The the same applies to the second toner image.

For this purpose, it points to the generation of the air cushion air used has a correspondingly low temperature. It is also possible that the air cushion also preheats the substrate at the same time should. For this purpose, warm or hot air is applied to the substrate applied.
