Filed:

Oct 31, 2002

Appl. No.:

10/286406

Inventors:

Charles W. Simpson - Lakeland MN
James A. Baker - Hudson WI
A. Kristine Fordahl - Hopkins MN
Susan E. Hill - Woodbury MN

Assignee:

Samsung Electronics Co., Ltd. - Suwon

International Classification:

B01D 5304

US Classification:

95143, 96132, 96135, 96142, 96153, 55515, 55519

Abstract:

A method and apparatus of the invention includes a method of removing airborne hydrocarbons from liquid electrophotographic printer exhaust comprises generating airborne hydrocarbon droplets as either vapor or mist during the transportation of electrophotographic ink or toner, directing substantially all of the air and hydrocarbon droplet mixture to a central collection point, forcing the air/droplet mixture to and through an oleophilic, substantially non-leaching collection media, and exhausting substantially hydrocarbon-free air from the electrophotographic printer. The method may further comprise inducing pressure in the printer with air pressure reduction to pull the exhaust through the collection media, for example with a pump or fan used to produce air pressure reduction. The method may comprise inducing airflow in the printer with ventilation holes or by the addition of a fan to provide a fresh air inlet. The air/hydrocarbon mixture may be directed to the collection media by a transportation system.

International Classification:

G03G 9/125

US Classification:

430115, 430116, 43013722

Abstract:

Electrophotographic ink compositions display reduced malodor effects when at least one antagonistic odor vector compound for C, Cand Chydrocarbons is present in the ink composition. The use of appropriate amounts of the antagonistic odor vector compounds for C, Cand Chydrocarbons does not adversely affect the functional imaging properties of the ink.

James A. Baker - Hudson WI, US

Assignee:

Samsung Electronics Company - Suwon

International Classification:

G03G 9/13

US Classification:

430115, 430114

Abstract:

The invention provides liquid electrographic toner compositions comprising a liquid carrier having toner particles and at least one soluble polymer dispersed in the liquid carrier. The liquid carrier has a Kauri-Butanol number less than about 30 mL. The toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions. The soluble polymer is present in an amount of from about 1% to about 10% by weight based on toner particle weight. The absolute difference in Hildebrand solubility parameters between the soluble polymer and the liquid carrier is less than about 3. 0 MPa. In one aspect of the invention, the soluble polymer that is incorporated in the toner composition has no more than about 30% weight ratio chemical constitution variance from the chemical constitution of the S material portion of the amphipathic copolymer.

International Classification:

G03G 9/08

US Classification:

430108100, 430111400, 430109100, 430137100

Abstract:

A low temperature fusing dry electrographic toner composition has a plurality of dry toner particles, wherein the toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions. The dry electrographic toner composition comprises a non-volatile plasticizer in an amount effective to reduce the First Heat Exposure Tby at least about 10 C. as compared to a like electrographic toner composition that does not comprise non-volatile plasticizer. The plasticizer plasticizer is sufficiently non-volatile that the Second Heat Exposure Twill not increase by an amount greater than about 5 C above the First Heat Exposure T. Methods of making and of using these compositions are also provided.
