A temperature sensor riding on the fuser roller changes resistance affecting current flow from engine control board, through sensor, back to engine control board. Debre buildup under sensor and degredation of sensor will affect normal operation. Thermal fuse only protects from possible fire starting; heating lamp/ceramic strip most always blows first. Over heating usually due to engine control board but in LJ III was due to AC power module stuck, supplying continuous 24 Volts DC to turn on lamp; this lamp always has 120VAC incase you don't unplug printer first.... If fuser heats without blowing... clean sensor within fuser assy with que tip and alcohol or replace fuser if paper being overheated first; then engine control board second.

What is the electrophotographic drum?

Its the central part of the laser printer. The drum is a metal cylinder that is coated with a light-sensitive insulating material. When a beam of laser light strikes the drum, it becomes a conductor at the point where the light hits it. As the drum rotates, the laser beam draws an electrostatic image upon the drum, called the image. The undeveloped or latent image is passed by a supply of dry ink or toner that is attracted to it. The drum turns and brings this image in contact with the paper, which attracts the toner from the drum. The paper is passed through a fuser that is made up of hot rollers, which melts the toner into the paper.
