The toner on the photosensitive drum surface is transferred onto the paper according to the positive
charge from the back side of the paper. Each color’s toner image is transferred in order of M, C, Y,
and K, and forms one toner image overlaying one color’s image on another.
Separation stage

  Separation stage
The paper is separated from the drum by its elasticity (Curvature Separation). The static charge on
the back side of the paper is decreased with the electrostatic eliminator in order to stablize the
feeding operation and prevent the crescent spots of printing image under the low temperature and
low humidity environment.
Fusing stage
The toner image is fused onto the paper in this stage. The toner image transferred onto the paper
through the transfer stage can be smeared easily by hands since it is only attracted to the paper by
the static electricity. The paper and the toner on it are fused by pressure, fused and secondary
colored by heat to be a permanent image.

  Fusing stage
The toner image on the paper is fused onto the paper by using the on-demand fuser method in this
step. This printer utilizes the ceramic heater with lower heat capacity, which warms up quickly, does
