Fusing process

1.When the paper reaches the fuser, the toner image is transferred on the paper, but not yet fused to the paper.

2.The transported paper passes between the heated roller and the back-up roller. The heated roller’s temperature is approximately 338°F (170°C).

3.When the paper with toner image passes between the heated roller and the backup roller, the heat from the heated roller in combination with the pressure between the two rollers, melts the toner, fusing it to the paper.

4.The fused paper then separates from the rollers and is transported out of the printer into the output bin or is routed back into the printer for printing on the other side of the duplex print.
