摘要： A toner sealing system is described including a seal having first and second alignment features. The seal is selectably installable on one of a first toner container of a first type and a second toner container of a second type. The first alignment feature is matable with a first corresponding alignment feature on the first toner container when the seal is installed on the first toner container for aligning the seal to the first toner container. The second alignment feature is matable with a second corresponding alignment feature on the second toner container when the seal is installed on the second toner container for aligning the seal to the second toner container. Embodiments include those wherein the first alignment feature does not align the seal to the second toner container, and the second alignment feature does not align the seal to the first toner container.

摘要： Provided is a toner blend composition comprising a first pigmented toner and a second toner that is devoid of any pigment additive, i.e., a ‘non-pigmented or clear toner’. The non-pigmented or clear toner is about 1% to about 15% by weight of the toner blend composition. The resulting inventive toner blend composition surprisingly exhibits similar print density on a page compared to a fully pigmented toner. Moreover, this toner blend composition exhibits improvement in toner usage per page, thus lowering toner cost compared to a fully pigmented toner. The non-pigmented or clear toner may be used in combination with either a monochrome or conventional toner using a carbon black pigment, or a chemically processed toners (‘CPT′’) toners using a black pigment, magenta pigment, yellow pigment or a cyan pigment.

摘要： A magnetic sensor array device is described that is constructed with multiple single sensor die, diced out of a wafer individually and packaged in a multi-chip module (MCM). The device comprises an array of multi-axis magnetic sensors that can measure the multi-dimensional magnetic field of an arbitrary sized two-dimensional region with high spatial resolution, reduced sensing distance, higher measurement throughput, tolerance to motion, improved temperature measurement, and improved yield when placed on a circuit card comprises part of an authentication system including a physical unclonable function (“PUF”), a substrate, a plurality of magnetized particles randomly dispersed in the substrate, and a PUF reader constructed using one or more of the magnetic sensor array devices wherein the PUF reader measures the magnetic field at multiple locations in close proximity to the magnetized particles. The measured magnetic field data may be compared to previously enrolled data to assess authenticity.

摘要： Magnetic PUFs (Physical Unclonable Function) may utilizes a single 3-axis Hall-effect sensor for enrollment. When a PUF is manufactured, a Hall-effect sensor is used to model the PUF disk and store that data where it may be accessed. This process is called “enrollment.” This invention improves upon the PUF implementation by introducing controlled variability into the enrollment, the reading of the PUF data from the Hall-effect sensors (the number and position of read sensors), the sampling method of the read sensor(s), and the processing of the PUF data.

摘要： A toner cartridge according to one example includes first and second alignment guides that extend outward from a first side and a second side of the toner cartridge, respectively, for positioning the toner cartridge. The first and second alignment guides define a pivot axis about which the toner cartridge is pivotable relative to an imaging unit when the toner cartridge is installed on the imaging unit. An engagement member is positioned on a rear of the toner cartridge for receiving a bias force for biasing the toner cartridge about the pivot axis when the toner cartridge is installed on the imaging unit. The engagement member is positioned next to the bottom of the housing. The engagement member includes an angled contact surface that faces upward and rearward for contacting a corresponding hold-down on the imaging unit when the toner cartridge is installed on the imaging unit.

摘要： An assembly for use in an electrophotographic image forming device includes a housing having a reservoir for holding toner. The housing includes a wall having an inner surface forming a boundary of the reservoir and an outer surface opposite the inner surface. A toner agitator is positioned in the reservoir and has a rotatable shaft. The shaft includes an end portion that passes through an opening in the wall. A gear is mounted on the end portion of the shaft outside of the reservoir and is rotatably coupled to the shaft. An annular seal encircles and is in contact with an outer circumferential surface of the shaft. The annular seal is positioned between an inner axial face of the gear and the outer surface of the wall. The inner axial face of the gear contacts the annular seal and presses the annular seal against the outer surface of the wall.

摘要： A toner composition having improved toner usage efficiency, wherein toner particles having an average size range of 1-25 μm may be mixed with an extra particulate additive package including a first small silica surface treated with both a silane and an aminosilane having a primary particle size of about 5 nm-20 nm, a second fumed silica having a primary particle size of 30 nm-60 nm, a third silica having a primary particle size of about 70 nm-120 nm, an electro-conductive titania having a primary particle size of 30 nm-60 nm and an acicular titania having a size of about 1.6 μm to 1.7 μm in length and about 130 nm in diameter. An alternative embodiment of the extra particulate additive package does not include a third silica having a primary particle size of about 70 nm-120 nm.
