* 25 Selection of area to be erased in non-original area
automatic erasure
This bit is used to make a setting associated with
the non-original automatic erasure mode (appli-
cation function).
1.
Selection of the area to erase
There are two methods for selecting the area to
be erased, "rectangular erasure" and " tilted eras-
ure." Select the desired method.
· Tilted erasure: The original is not rectangular
(e.g., circular original).
· Rectangular erasure: The original is rectangular
(e.g., original of a standard size).
If a rectangular original is placed in a tilted posi-
tion, black stripes may appear in the "rectangu-
lar erasure" mode. If there is a black area on the
periphery of the original, this area may be judged
as being outside the original, resulting in improper
erasure of the area outside the original. In such
a case, the "rectangular erasure" mode is se-
lected automatically.
2.
Selection of identification level
When the original is dark or external light (from
the fluorescent lamp or sun) enters the machine,
it becomes sometimes difficult to discriminate
between the area inside the original and the area
outside it. In such a case, the original area iden-
tification level can be changed.
Remarks:
In the key operator mode, you can use the
memory switch that has a non-original area au-
tomatic erasure function. This memory switch
allows you to select the area to be copied when
copy paper is selected manually.

• To copy only image size area determined by
the APS sensor, select "Erase the area out-
side the original."
• To copy the entire area of the original to the
selected paper, select "Do not erase the area
outside the original."
Note:
The APS sensor is effective if copy paper is se-
lected manually.

* For rectangular original density (dark original /
darker original)
Use this mode to set the density level
threshhold value to the dark when copying a
news article on a newspaper.
(This mode is for copying a newspaper whose
texture color is dark. Margin for interference light
decreases.)
* ADF shadow: Use this mode to set the density
level threshold to the light side in order to
prevent the ADF from being detected as an
original when it is closed sightly. However, the
inner area of an original may be mis-judged as
the outer area and lineal image failure tends to
occure.
* Threshold for coping with interference light
Use this mode to increase the probability of
copier to operate normal, when it is hard to
prevent interference light penetrating to scan
area, and when copying comparatively low
density (bright texture color) original.
