2. Operational descriptions
A. Outline
The paper transport section serves the function of transferring
paper from each paper feed port to the registration roller section.
Paper from manual feed, paper feed tray units 1 and 2 (optional),
and the right paper feed tray of the paper feed tray units 1 and 2 is
transported horizontally, whereas paper from the left paper feed
tray of the paper feed tray units 1 and 2, paper feed tray 3 and
paper feed tray 4 is transported vertically to the registration roller
section.
After the leading edge of the paper is synchronized with the leading
edge of the drum image in the registration roller section, the paper
that is transfer printed with the image in the transfer section passes
through the fusing section and is discharged either face-down or
face-up.
