摘要： Printers are provided having wax management systems. In one aspect, a printer has a print engine provides a toner image on a receiver using a toner having a binder polymer and a wax and a fuser having a contact surface that heats the toner at least to a glass transition temperature for the toner and the wax at least to an incorporated melting temperature to cause at least some of the wax to separate from the toner. A controller allows the toner image to cool to form a fused toner image having a viewing surface and the wax to cool to form first portions of the viewing surface with wax globules and second portions without wax globules. A wiping system wipes the viewing surface to move at least some of the wax from the wax globules onto the second portion when the toner image and wax are cooled.

摘要： An electrophotographic method for producing fused toner images on a receiver medium comprising the steps of: forming an electrostatic image pattern on an image forming member; developing the image pattern on the image forming member with fusible toner particles thereby forming a toner image thereon; transferring the toner image to the receiver medium; and heating the toner image to form a fused toner image on the receiver medium, wherein an amount of a plasticizer is added to the toner particles of the toner image after formation of the toner image on the image forming member and prior to or concurrent with fusing of the transferred toner image on the receiver medium, further wherein the amount of plasticizer added is effective in lowering the Tg of the toner below that of the toner under prevailing ambient conditions in the absence of the added plasticizer. The current invention overcomes the limitations of the prior art because the plasticizer is added immediately before fusing, thus avoiding toner clumping upon storage, as well as eliminating the high cost associated with a custom manufactured receiver that already contains plasticizer.
