2-1-2 Process section

The process section consists of the developing section, the process units that integrate the drum and cleaning sections,
the main charger unit on each process unit that can be detached and refitted, and the LED print head mounted to the
printer frame.

(1) Developers and drum unit

The process units have the same shape for four colors: magenta, cyan, yellow, and black. In the process unit, the drum
surface is charged with discharge of the main charger wire in the main charger unit and an electrostatic latent image is
formed on the drum surface by irradiating LED light (dots) from the LED print head. The electrostatic latent image is pro-
cessed into a toner image through toner transfer from the developing magnet A roller and then the toner image is trans-
ferred to the transfer belt of the transfer unit. For a color image, four color toner images are superposed and transferred.
After transfer is complete, toner remaining on the drum surface is chipped off with the drum cleaning blade of the cleaning
section and is ejected out of the process unit with the cleaning screw. Also electric charge remaining on the drum surface
is eliminated by irradiating the eraser lamp for preparing for next discharge of the main charger wire.
