  • Patent number: 11687018
    Abstract: The object of the present invention is to fix the thermoplastic ink in powder state used to print digital images by means of an electrographic laser motor on self-adhesive web media such as self-adhesive paper webs, self-adhesive film webs such as polypropylenes, polyethylenes, polyesters, and vinyls, with different thicknesses and finishes, allowing work to be stopped between one production batch and another and/or stops for self-calibration of the print motor without changing the self-adhesive media, preventing problems due to overheating of the printout. The apparatus according to the present invention makes it possible to enhance the fixed prints with a glossy, matt, or holographed finish, without the need for subsequent treatment and/or the use of chemical materials afterwards, offering greater flexibility and economy at work.

  • Patent number: 11635714
    Abstract: A fixing apparatus includes a first rotary member, a heating element, a second rotary member, a nip member, a reflection member, and a support member. The support member configured to transit to a pressurized state and a non-pressurized state, the pressurized state being a state in which a first position and a second position of the support member are pressurized in a pressurization direction toward the second rotary member, the non-pressurized state being in which the pressurized state of the support member is released. The support member includes a contact surface in contact with the reflection member in the pressurized state. The contact surface takes such a posture that a center position between the first and second positions in the rotation axial direction is close to the second rotary member rather than the first and second positions in a case where the support member is in the non-pressurized state.
