*1 Second paper feed paper mis-centering correc-
tion
PS1 (paper mis-centering) is mounted at the exit
of the registration roller to detect mis-centering
or inclination of paper fed from the second paper
feed unit. The image processor uses the mis-
centering information detected by PS1 to correct
the image write position, thus shifting or rotating
the image write position on the mis-centered or
inclined copy paper in order to match the docu-
ment (scanned image) position with the copy
paper position.

The distance between the registration roller and
the transfer and separation corona unit of this
machine is made long to ensure image position
correction operation. To assist paper convey-
ance between the registration roller and the
image transfer and separation corona unit, a pre-
transfer roller is provided just before the transfer
and separation corona unit.
