Abstract
A drum heater consisting of a plurality of vanes made preferably from mica material and having multiple separate heater wire channels controlled from an electrical cable is provided for heating the interior of a printer drum or fuser. The drum heater has element wires, which can be operated in two different modes, and which are wound around eight mica vanes. The mica vanes are held together on both ends with mica end caps for assembly, electrical isolation and thermal isolation. The mica vanes additionally define protruding tabs for attachment of wire restraining and protecting mica panels.
