14. TRANSFER UNIT
14.1 General Descriptions
Transfer is a process of decaling a toner image from the photoconductive drum onto paper.
A toner image formed on the photoconductive drum is temporarily transferred onto the transfer belt,
and the toner image is then transferred from the transfer belt onto paper. The first transfer from the
drum to the transfer belt is called the 1st transfer, and the second transfer from the transfer belt to paper
is called the 2nd transfer. To form a color image, the images of yellow (Y), magenta (M), cyan (C) and
black (K) are transferred and overlaid on the transfer belt in order, and then the overlaid images are
transferred onto paper.
After the completion of the 2nd transfer, the residual toner on the transfer belt is scraped off by the
transfer belt cleaning blade and then transported to the waste toner box.
