(7) Fusing
Fusing is a process of melting and fixing the toner
on the paper.
Method : The melting point of the toner (main
ingredient: resin) is 100~110°C.
(Heat) The 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
adherence of the melted toner to the
paper.
Heat and pressure are applied to the
paper when it passes between the fuser
roller and pressure roller.
(Fusing) The toner is fixed on the paper.
(8) Cleaning
Cleaning is a process of recovering the residual toner
on the photoconductive drum.
1. The cleaning brush scrapes off the excessive
toner and paper wastes. The flicker scrapes off
the toner on the brush.
Also, too pervent the cleaning blade from
scratching the surface of the drum to make a
circumferential streak, the varistor is attached
between the brush and earth.
2. Cleaning blade scrapes off the residual toner on
the drum.
3. The recovery blade picks up the scraped toner.
