Fusing process

[A]: Paper
[B]: IH coil (induction heater)
[C]: Heat roller
[D]: Fusing belt
[E]: Transfer belt
[F]: Transfer roller
[G]: Pressure roller
[H]: Fusing jam detection sensor
After the toner image has been applied to the paper [A], it passes through the
fusing unit. The fusing unit contains the heat roller [C]. The IH coil [B] heats the
heat roller. The heat roller heats the fusing belt [D] which is responsible for melting
the toner on the paper. Additionally, the paper is pressed between the fusing belt
and the pressure roller [G], and the melted toner is bonded to the paper.
When the paper exits the fusing unit, it advances to the exit tray. The fusing jam
detection sensor [H] detects the paper. A heat roller rotation sensor is used to
ensure that the heat roller is rotating.
