摘要:
A physical unclonable function (PUF) apparatus having magnetic particles is disclosed. The magnetic field data and the image view of the magnetic particles in the PUF apparatus are difficult to counterfeit. A PUF apparatus may be incorporated into a user-replaceable supply item for an imaging device. Further, a PUF reader may be incorporated into an imaging device to read the PUF. Other systems are disclosed.

摘要:
The present disclosure relates to the use of radiation cured coatings that may be used in a device within an image forming apparatus. The coating composition may include a reactive oligomer capable of radiation curing having a number average molecular weight (Mn) of greater than 1500. A reactive diluent may then be combined with the reactive oligomer, which diluent is also capable of radiation curing and which has a Mn of less than or equal to 1500. The reactive diluent may be present at a level of less than fifty percent by weight of the coating composition. The coating composition may be present at a solids level of 90-100%.
摘要:
A nozzle plate for a micro-fluid ejection head, a method of making a hydrophobic nozzle plate, and a method for improving the resiliency of a nozzle plate. The nozzle has a photoimageable hydrophobic polycyclic polyolefin layer derived from an epoxy functionalized polynorbornene.

The present disclosure relates to an image forming component. The component may include a urethane body, comprising polydiene containing a residual double bond available for oxidation, and including a surface, wherein said double bond is oxidized. The component may also include a first conductive additive including an alkali metal salt, wherein the first conductive additive catalyzes the oxidation of the polydiene and a second conductive additive including an inert conductive additive that does not catalyze the polydiene oxidation, wherein the image forming component exhibits a surface resistivity in the range of 1.0×109 to 1.0×1012 ohm-cm, when characterized at 15.6° C. and 20% RH.
摘要:
An endless electrophotographic member, such as a developer roller, which indicates an improved resistance to nip banding. The improvement to nip banding may be provided by the use of an organic salt within a roller surface region. The roller may provide, at a nip location, a resistive surface layer having an electrical resistance that avoids the development of nip banding and relatively dark regions on printed media.
摘要:
Developer roll having a conductive or semi-conductive soft rubber core and a coating deposited in the soft rubber core wherein the coating has a conductive agent. The outer surface of the soft rubber core is modified before the coating is deposited onto the outer surface of the soft rubber core. Methods for making the same.
