Abstract
Toner xerographically adhered to a material, such as a sheet of paper, may be removed using a solvent-based or solventless approach. The application of ultrasonic tamping, scraping and brushing may aid in removing toner particles. In a solvent-based approach, a solvent may be applied generally or the solvent may be targeted specifically to the toner covered portions of the material to loosen the adhesive securement of the toner to the material. Thereafter, the toner is subjected to a mechanical abrasion using ultrasonic and physical agitation to cause flaking of the toner.
Claims30
A method of removing toner from a material comprising:
- applying a solvent to the toner to weaken the adhesive attachment of the toner to the material;
- and
- mechanically removing the toner from the material.
A device comprising:
- a solvent applicator to apply a solvent to toner to weaken the adhesive attachment of the toner to a material;
- and
- an ultrasonic agitator to ultrasonically agitate the toner to facilitate the removal of the toner from the material.
A method of removing toner from a material comprising:
- applying a solvent to the toner to weaken the adhesive attachment of the toner to the material without substantially dissolving the toner;
- and
- removing the toner from the material.
A method of removing toner from a material comprising:
- applying ultrasonic energy to the material;
- and
- removing the toner from the material.
A device comprising:
- an ultrasonic agitator that agitates a material on which a toner is printed;
- and
- a transport system that transports said material past said ultrasonic agitator.
