H. Step 6 (separation)
Figure 2-113
The copier uses a curvature separation method,
which separates copy paper from the photosensi-
tive drum by the rigidity of the paper. However, thin
paper could at times fail to separate from the drum
because of its low rigidity. To prevent such a prob-
lem, a positive charge is applied to the separation
static eliminator, thereby weakening the static
attraction for better separation.
Reference:
If the image on the photosensitive drum fails to
transfer to copy paper because of a jam or the
like, the transfer charging roller could become
soiled with toner.
To prevent such a problem, the copier uses a
positive transfer voltage when the scanner is
moving in reverse or during post rotation, thereby
returning the positively charged toner on the
transfer roller to the photosensitive drum.
