Edge Erase
The Edge Erase feature (Figure 27) enables you 
to eliminate unwanted marks near the edges of 
the original from the output copy.
This feature offers two options:
•No Erase
•Variable Erase
When you are making 2-sided copies, edge erase 
is applied to both sides of the output.
KEY POINT:Edge Erase varies according to the 
reduction/enlargement ratio that you set. For 
example, when a reduction of 50% combined with 
an edge erase width of 30 mm results in a 15 mm 
edge erase.
In order for the Edge Erase feature to function 
correctly, the original must be registered on the 
Document Glass against the registration arrow.
After you select an Edge Erase option, the Added 
Features screen displays a check in the feature 
check box beside the set values.
NOTE:The System Administrator sets a default 
Edge Erase. The output reflects the greater of the 
two values. For example, if the default Edge Erase 
value is 3 mm and you request an edge erase of 2 
mm, the output copy reflects the default value. If 
you request an edge erase of 5 mm, the output 
copy uses a  5 mm edge erase.

7 Variable Erase for edges
The Variable Erase option, illustrated in Figure 29, 
enables the copier/printer to vary the amount of 
erasure from 0 to 50 mm in 1 mm increments. The 
same amount of erasure is applied to both top and 
bottom edges or right and left edges of the 
document.
The Centre Area Erase option allows you to 
remove the shadow caused by the centre binding 
of bound documents when they are copied. The 
factory default setting for Centre Erase is 0 (zero).
Select the up arrow to increase the amount of 
erasure or the down arrow to decrease the 
amount of erasure.
KEY POINT:If your document contains an image 
area that extends to the edges of the document, 
and you do not want any of it to be deleted, use 
the Variable Erase arrow buttons to set the erase 
value to zero. Select the Margin Shift feature, Auto 
Shift option, from the Added Features tab. Ensure 
that 100% is selected for Reduce/Enlarge feature 
on the Basic Copying tab.
NOTE: Keep the following notes in mind when 
using Centre Area Erase:
•Do not use Centre Area Erase with the 
following features:
– Multiple-Up
– Repeat Image
•The Centre Area Erase setting in the Variable 
Erase feature is the same as the centre erase 
setting of Bound Originals.
•For some original image sizes, Centre Area 
Erase does not occur exactly in the centre of 
the output image.

Original Size
Use the Original Size feature (Figure 31) to 
specify the original document size as one of a 
number of standard international or US sizes. You 
can also manually specify the dimensions of non-
standard input or you can select the Auto Detect 
option to enable size identification by the copier/
printer.
KEY POINT:Avoid putting items (pens, pieces of 
paper, etc.) that you do not wish copied onto the 
Document Glass. Undesirable copy output may 
occur.
•If you select Auto Detect, the DocuColor 12 
performs a prescan and assumes the original 
document and anything that is on the 
Document Glass (pens, pieces of paper, etc.) 
are to be copied. 
•If Reduce/Enlarge Auto% is also selected, the 
image is reduced to include the undesired 
object.
•If Paper Supply Auto Paper is selected, 
oversized paper may be selected for copying 
to include the object in the output image.

6. Image Quality
Overview
Figure 1: Image Quality Tab
The Image Quality features, listed on the 
Image Quality tab (Figure 1), allow you to 
optimize the output copy quality. You begin 
your adjustment by indicating the type of 
original document you have. Then you change 
settings for specific image quality factors such 
as lightness and darkness, sharpness, or 
colour.
Examples of the images printed with default 
settings are provided on the following pages. 
More detailed information is also provided 
about the following Image Quality features:
Original Type
The selection of the correct Original Type (for 
example, Photo & Text, Text, Photo, Graphics 
& Maps) ensures that the DocuColor 12 uses 
its fullest scanning capability for that 
document type.

The Preset Colour Balance option automatically 
adjusts Image Quality settings to produce output 
with balanced image tones.
Lighten/Darken
The adjustment of lightness or darkness will 
sometimes improve the output quality.
Colour Shift/Saturation
This feature allows you to shift all of the copy 
colours toward the adjacent hue, as well as adjust 
the overall richness of colour on the output copy.
Sharpness
The Sharpness feature allows you to adjust the 
amount of edge definition on the output.
Variable Colour Balance
The Variable Colour Balance feature enables you 
to set the balance of Yellow, Magenta, Cyan, and 
Black by the varying degrees of density for each 
colour.
When you make changes to the Image Quality 
features, remember that outside factors, such as 
the quality of the original document, also affect 
output quality.

are applied to the entire output copy.
KEY POINT:When you select an option other 
than the default for a feature and then save your 
selection and return to the tab, a check mark 
displays near the feature name and the selected 
value or option displays under the feature name.
