An article including a container with an opening adapted to accommodate and dispense the contents therefrom; a closure in contact with the container; a signal module in communication with the closure; and a transmitter module adapted to send a signal or signals from the signal module to a receiver module resident in a target printing machine.

Communicating dispensing article

An article including: a container with an opening which container is adapted to accommodate and dispense the contents therefrom; a closure seal in contact with the container; and a signal module in communication with the closure. When the closure is infringed by an operator, the signal module will be activated causing, for example, the container to vibrate for a set period of time. This container may be sealed by first and second seals.

Communications cartridge

Cross-linked toner resin having linear portions and cross-linked portions of high density microgel particles, where the toner resin is an unsaturated polyester resin, is prepared using a liquid chemical initiator such as 1,1-bis(t-butyl peroxy)-3,3,5-trimethylcyclohexane so that the cross-linked resin achieved contains less than 0.20 percent by weight of acids. In particular, the cross-linked toner resin is free of benzoic acid. The method of making the cross-linked toner resin includes (a) spraying the liquid chemical initiator onto the unsaturated polyester resin prior to, during or subsequent to melting of the unsaturated polyester resin to form a polymer melt; and (b) subsequently cross-linking the polymer melt under high shear to form the cross-linked toner resin.

Cross-linked polyester toners and process of making such toners

A process for the preparation of an unsaturated polyester which comprises (i) reacting an organic diol with a cyclic akylene carbonate in the presence of a first catalyst to thereby form a polyalkoxy diol, and (ii) optionally adding thereto a further amount of cyclic alkylene carbonate in the presence of a second catalyst, and (iii) subsequently polycondensing the resulting mixture with a dicarboxylic acid.

Polyester process

A toner composition comprised of a polyester resin with hydrophobic end groups, colorant, optional wax, optional charge additive, and optional surface additives.

Toner and developer compositions

A die for the preparation of a toner resin in an extruder having a housing defining a housing aperture therein and a conveyor for conveying the resin through the housing aperture to form a stream of resin is provided. The die includes a member connected to a first end of the housing. The member defines an opening therethrough. The cross sectional area of the opening is progressively reduced in the direction of the stream of resin for at least a substantial portion of the opening.

Extruder die insert plate system

An apparatus and process for reducing accumulation of toner from the surface of an electrode member in a development unit of an electrostatographic printing apparatus by providing an inorganic coating on at least a portion of the electrode member.

Inorganic coated development electrodes and methods thereof

An apparatus and process for reducing accumulation of toner from the surface of an electrode member in a development unit of an electrostatographic printing apparatus by providing an organic coating on at least a portion of the electrode member.

Organic coated development electrodes and methods thereof

An apparatus for reducing accumulation of toner from the surface of an electrode member in a development unit of an electrostatographic printing apparatus which includes providing a low surface energy coating on at least a portion of the electrode member.

Coated development electrodes and methods thereof

An apparatus for the preparation of a mixture of toner resin and initiator, to form a toner resin or toner mixture including cross-linked microgel particles is provided. The apparatus includes a toner extruder having the resin being conveyed therethrough and an adder for adding the initiator to the toner resin in the toner extruder to form the toner resin or mixture. The apparatus also includes a measurer for measuring the cross-linked microgel particles in the toner mixture substantially immediately after mixing in the toner extruder and transmitting a signal indicative of the quantity of cross-linked microgel particles in the toner resin or mixture. The apparatus also includes a controller for controlling the addition rate of initiator in response to the signals from the measurer.

Feedback control system for polymer modification of toner resins and

A method and apparatus for determining the level of roughness in a paper or other substrate to be processed in a machine, and for correspondingly adjusting the machine parameters that are affected by the different levels of substrate roughness, before the substrate is processed through the machine.

Method and apparatus for detecting substrate roughness and controlling

A process for removing a xerographic image from a substrate which comprises contacting the image with an aqueous solution comprised of water, a surfactant, ionic salts and caustic reagent.

Deinking processes

Processes for low melt crosslinked toner resins and toner
