The toner on the paper is molten and pressed into the paper as it passes between the heat roller (A) and the press roller<br />
(B) in the fuser unit.<br />

The heat roller has a halogen lamp inside which continuously turns on and off by the thermistor to maintain the constant<br />
temperature onto the heat roller surface.<br />
The heat roller is resin coated by florin to prevent toner from accumulating on the roller after a long run. Care must be<br />
taken while handling the heat roller not to scratch the roller surface as doing so may result in print problems.<br />
The heat roller has four claws which are continuously in contact with its surface. These claws prevent the paper on<br />
which toner has been fused from being wound around the heat roller causing paper jam.<br />
The pressure roller is made of the heat-resistant silicon rubber. This roller is used to strongly press the paper towards<br />
the heat roller by means of coil springs.<br />
The temperature of the heat roller is constantly monitored by the engine board using the thermistor and triac. Should the<br />
temperature of the heat roller exceed the predetermined value, the thermal cutout is activated to effectively disconnect<br />
the heater (halogen) lamp from power.<br />
