4-Step Copy Process

In this equipment, 4 color process units (EPU), which include a drum, a developer unit and a main
charger, for yellow, magenta, cyan and black are placed in parallel. Colors are developed in the order of
Yellow (Y) → Magenta (M) → Cyan (C) → Black (K). An image with the 4 developed colors is transferred
on the transfer belt by layering the colors one by one (1st transfer). Then the image is formed on a
sheet by being transferred from the transfer belt by the 2nd transfer roller (2nd transfer).
