摘要:
A fuser assembly including a heater assembly that includes a heater body, the heater body includes a substrate that extends across the fuser nip. A plurality of retention features are defined on a protective layer covering the surface of the substrate. The protective layer includes a first layer and a second layer, the second layer including a plurality of passages extending from an outer surface of the second layer to the first layer and dimensioned and positioned to allow a lubricant to pass through the second layer between the retention features and the outer surface of the second layer.

An image-forming device includes a belt based fuser for fixing an image to a media substrate. The fuser includes a heater having a base component with at least one heating element disposed thereon. The heater further includes a covering layer covering the at least one heating element providing a substantially even surface to abut a belt. Unevenness, which may be present on the substantially even surface, has a height, defined by a base and a peak, of less than about 10 μm. A process for producing the heater is also disclosed. The process includes disposing one or more heating elements on a base component of the heater, covering the heating elements of the fuser heater with a covering layer and providing a substantially even outer surface to abut a fuser belt.
摘要:
A fuser has a protuberance extruding lengthwise from the surface of a heater opposite the interior surface of an endless belt and is positioned in transverse relationship to the interior surface of the endless belt. A pressure roller defines a nip with the endless belt wherein the nip has an entrance side and an exit side and wherein the position of the protuberance adjacent to the nip creates pressure upon the endless belt. The print media sheet is driven through the nip in reaction to the pressure applied by the pressure roller to the belt. The position of the protuberance and the pressure created upon the endless belt directs the lubricant from the endless belt surface to the nip.

A heater assembly includes a heater housing with strain relief features for wires associated with electronic components, such as a thermistor and/or thermal cut-off (TCO) device, coupled to a heating element. The heater assembly may be used in a fixing device or fuser in an image forming apparatus including, but not limited to, printers, copiers, faxes, multifunctional devices or all-in-one devices.

摘要:
A fuser has a heater housing extending through an endless belt with end caps on the housing adjacent to opposite lateral sides of the belt. The end caps have inner flanges spaced radially outward from a center portion and radially inward from the opposite marginal side edge portions of the belt so as to define clearance therebetween. Protuberances on the inner flanges of the end caps project toward opposite marginal edge portions of the belt and are circumferentially spaced apart to reduce belt skew relative to the end caps by either decreasing the surface area of contact of the inner flanges with the opposite marginal side edge portions of the belt to reduced surface areas of contact of protuberances therewith or decreasing the radial height of the clearance between the inner flanges and opposite side edge portions of the belt to the reduced radial height between the latter and the protuberances.
