Printing Process

6
This machine uses four PCUs, four development units, and four laser beams for color printing. Each PCU
contains a drum, charge roller, cleaning brush, and blade.
The toner image on each drum is moved to the transfer belt. The four colors are put on the belt. All four
toners are put on the belt at the same time. Then the completed four-color image is moved to the paper.
1. Drum charge:
The charge roller gives the drum a negative charge
2. Laser exposure:
The laser beam from the laser diode (LD) goes through the lens and mirrors and to the drum. To make
a latent image on the drum, the machine turns the laser beam on and off.
3. Development:
The development roller moves negatively-charged toner to the latent image on the drum surface. This
machine uses four development units (one for each color).
