(5) Fusing

The toner on the paper is molten and pressed into the paper as it passes between the heat roller A

and the press roller B in the fuser unit.

Figure 4-1-10 Fusing

The heat roller has a halogen lamp inside which continuously turns on and off by the thermistor to

maintain the constant temperature onto the heat roller surface. The temperature is approximately

160 °C while the printer is idle; approximately 175 °C (Normal paper) and 185 °C (Thick paper)

while printing.

The heat roller is resin coated by florin to prevent toner from accumulating on the roller after a long

run. Care must be taken while handling the heat roller not to scratch the roller surface as doing so

may result in print problems.

The heat roller has four claws which are continuously in contact with its surface. These claws

prevent the paper on which toner has been fused from being wound around the heat roller causing

paper jam.

The pressure roller is made of the heat-resistant silicon rubber. This roller is used to strongly press

the paper towards the heat roller by means of coil springs.

The temperature of the heat roller is constantly monitored by the engine board using the thermistor

and triac. Should the temperature of the heat roller exceed the predetermined value, the thermal

cutout is activated to effectively disconnect the heater (halogen) lamp from power.
