By applying a minus charge to the belt unit, the toner adhered to the exposure drum is
transferred to paper.

Memo:
The four colors of toner are coated in turn on the paper to form a color: First comes black (K),
then yellow (Y), then magenta (M), and then cyan (C).

<Function of EL PCBs>
After toner is transferred, a surface potential difference occurs between the exposed areas
and non-exposed areas on the exposure drum. The lamp (LED) of each EL PCB evenly
irradiates the surface of the exposure drum to keep the surface potential constant, preventing
an image failure caused by a potential difference (appearance of a ghost image).
