The invention generally relates to the field of fusing powder toner images on receiver sheets. According to various aspects of the invention, methods and apparatus are provided of cleaning, only during standby, a pressure roller that cooperates with a fuser roller in fusing toner images. The pressure roller is cleaned with a cleaning pad mounted adjacent the pressure roller in an electrographic printer.
摘要:
A wicking device for applying toner release oil to the surface of a fuser roller of a reproduction apparatus. The wicking device includes a first rotatable roller that has a hollow interior and a porous capillary shell for pulling toner release oil from the hollow interior to the outside surface thereof. The wicking device also includes a second rotatable roller that is mounted within, and for rotation against, the surface of the hollow interior of the first rotatable roller for supplying and pushing toner release oil into the capillary shell of the first rotatable roller.
摘要:
A toner image is fixed to a receiving sheet by the application of pressure and heat applied between first and second pressure members. To prevent blistering of finished receiving sheets, a substantial temperature gradient is maintained between the two members which heats the image side of the receiving sheet adequately for fixing without excessively heating the overall sheet. The second pressure member contacting the side of the sheet opposite from the image is actively cooled by an air cooling device or the like as controlled by a logic and control in response to the temperature of the second pressure member.
