Samsung JC96-04653A fuser assembly is the fuser housing part listed in the ML-1630W service manual. It is identified for the AC220V version, so the exact part number matters when matching this assembly to equipment.
The manual lists the fuser’s working components, including a thermistor assembly, halogen lamp, heat roller and pressure roller. Together, these parts form the printer’s paper fusing unit, which applies heat and pressure as a page passes through. This description refers to Samsung part JC96-04653A, rather than the separately listed AC110V fuser assembly.
