* Output is controlled as follows to realizes the desirable separability and transferability.
Paper may not be separated from the drum sur-
face because of moisture or malfunction of the
transfer/separation charger during printing. As
the result, the paper enters into the cleaner and
causes jamming. To prevent this, a separation
finger is used to forcibly separate the paper
which was left around the drum.
(8) Fusing
Fusing is the process of melting the toner on
the paper and fixing it firmly on the paper.
Method : The melting point of the toner (main
ingredient : resin) is 100-110°C.
(Heat) Toner is melted by the heat of the
surface of the fuser roller.
+
(Pressure) The pressure roller is pressed
against the fuser roller by the
springs to increase the adherence
of the melted toner onto the paper.
Heat and pressure are applied to
the paper when it passes between
the fuser roller and pressure roller.
||
(Fusing) The toner is fused on the paper.
