A secure document printing and delivery management system includes one or more print delivery vehicles, each of which includes an onboard print device. When the system receives a print job from a requesting device, it will select a print delivery vehicle instruct the print delivery vehicle to navigate to a delivery location. Upon arrival at the delivery location, the system will detect and verify a security token presented by a recipient. In response to detecting and verifying the token, the system may print the document (if not already printed) and it will present the document to the recipient.

A process is disclosed for the preparation of developer compositions comprising: providing a first developer including carrier and a first toner comprised of resin, pigment, polyolefin, a first compatibilizer, a first charge control agent, and a first metal oxide surface additive; and, adding thereto a second developer including carrier, and a second toner, second compatibilizer, a second charge control agent, and a second metal oxide surface additive.

Dispensing toner additives via carrier dispense and clear toner

The present disclosure provides a process for the preparation of developer compositions comprising: a first developer comprised of carrier and toner comprised of resin, pigment, polyolefin, compatibilizer, charge control agent, and metal oxide surface additive, and adding thereto a second developer comprised of carrier, and second compatibilizer, charge control agent, and metal oxide surface additive. The second developer can be directly dispensed into a developer housing.

A method and apparatus for indicating a part number for a consumable to be used in an image production device is disclosed. The method may include generating a pre-printed label that includes one or more potential part numbers for the consumable with an indication area proximate to the one or more potential part numbers, the indication area including reactive material, attaching the preprinted label on packaging for the consumable, determining a desired part number from the one or more potential part numbers for the consumable, and indicating the desired part number for the consumable by activating the reactive material proximate to the desired part number.

The present disclosure relates to a process for preparing a polyester based magnetic toner composition. The toner composition includes one or more polyester amorphous binder resins, optionally a cystalline polyester resin, and spherical ferromagnetic particles. In embodiments, the toner is prepared from ferromagentic particles that have been previously encapsulated in an amorphous resin, a crystalline resin or a wax. In yet other embodiments, the process may be conducted under an inert gas such as argon to avoid oxidation of the ferromagnetic particles during toner preparation.

Magnetic toner compositions

According to embodiments illustrated herein, there is provided a black toner having a resin, an optional additive, and at least two or more colored pigments, and the at least two or more colored pigments are selected from the group consisting of a blue pigment, a green pigment, a red pigment, a magenta pigment, a cyan pigment, a yellow pigment, a white pigment, and mixtures thereof, and the black toner has a colorimetric value L* of about less than 30.

Methods for making customized black toners

A process for forming curable powder comprises providing an aqueous dispersion of particles of curable resin and optionally particles comprising at least one curing agent; aggregating the particles optionally with the curing agent to form aggregated particles; coalescing the aggregated particles to form fused particles; and removing the fused particles from the aqueous dispersion. By this process, a curable powder is formed. The curable powder may be used in powder coating.

A method of changing a color developer in a developer housing of xerographic marking system are disclosed, and may include supplying a chart divided into a plurality of color family sections or quadrants, selecting a new color to be installed in a developer housing corresponding to the color family section, purging old toner from the developer housing until a concentration of old toner is reduced to about 0.1% to 6.0% from its nominal concentration, installing a container of a new color developer in the developer housing, and running the marking system until the required concentration of the new color developer is attained.

Method by which an infinite number of colors may be used with a finite number of CCUs

According to embodiments illustrated herein, there is provided a black toner having a resin, an optional additive, and at least two or more colored pigments, and the at least two or more colored pigments are selected from the group consisting of a blue pigment, a green pigment, a red pigment, a magenta pigment, a cyan pigment, a yellow pigment, a white pigment, and mixtures thereof, and the black toner has a calorimetric value L* of about less than 30.

An improved 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 a composition coating comprising a water-emulsified polymer, lubricant and inorganic material on at least a portion of the electrode member.

Coating compositions for development electrodes

At least three differently colored toners, designed for use together in forming a color image in an image developing device, have substantially the same melt flow index value. By substantially matching the melt flow index values of at least three toners of a set of toners, it has been found that the resultant color image has an overall excellent image quality, i.e., an excellent overall gloss level without any gloss banding. The toners may be made to have substantially the same melt flow index value in a carefully controlled process that includes forming a single toner by feeding at least one binder and at least one colorant into a mixing device to form a mixture, upon exit of the mixture from the mixing device, measuring a rheology property of the mixture with at least one monitoring device, and comparing the measured rheology property to a target property range that the measured rheology property must be within in order for the single toner to achieve the desired melt flow index value, wherein if the measuring indicates that the rheology property is outside of the target property range, feed amounts of the at least one binder or of the at least one colorant into the mixing device are adjusted, grinding the mixture, optionally together with a portion of one or more external additives to be added to the mixture, classifying the ground mixture, mixing the classified mixture with one or more external surface additives to obtain the single toner having the desired melt flow index value, and repeating the steps for each additional differently colored toner.

Color-blind melt flow index properties for toners

A developer unit for developing a latent image recorded on an image receiving member to form a developed image is provided. The developer unit includes a housing defining a chamber for storing at least a supply of toner therein and a moving donor member spaced from the image receiving member. The donor member is adapted to transport toner from the chamber of the housing to the image receiving member in a development zone. The donor member receives toner from a reloading zone. The developer unit also includes an electrode structure and an electrical field establisher for establishing an electrical field between the donor member and the electrode structure. The electrical field establisher is spaced from the development zone and the reloading zone, to assist in cleaning toner from the donor member.

Developer units with residual toner removal to assist reloading

A cleaning apparatus that comprises a brush cleaner to remove particles from the imaging surface. The particles are removed from the brush cleaner using a detoning roll. The particles are loosened and separated from the detoning roll using a scraper blade. These loosened and separated particles, from the detoning device, are carried to a waste container by an air stream alone rather than using an augering system.

Brush cleaner with roll detoning and air waste removal

A cleaning method and apparatus that provides continuous lubrication to the cleaning blade preventing blade failure. The continuous lubrication is provided by a foam lubricating roll located downstream from the cleaning blade, in the direction of motion of the imaging surface. The foam roll utilizes the waste toner cleaned from the imaging surface to lubricate the cleaning blade.
