Original Type
The Original Type feature (Figure 2) enables you 
to define the kind of original document you wish to 
copy. After you have, the copier/printer 
automatically  makes fine adjustments to optimize 
the copy sharpness based on document type.
There are a number of document type choices 
available, as illustrated in Figure 3:
•Photo & Text
•Te x t
•Photo
•Graphics & Maps
After you have selected an Image Quality option, 
the Image Quality tab will display a check mark in 
the feature check box with the set values.
For the best copy quality, always select the 
Original Type that best describes your document.
NOTE:The System Administrator selects the 
default Original Type. The Original Type icon on 
the Feature Folder displays the currently selected 
Original Type as the default.

7 Photo & Text
Photo & Text is the best document type selection 
for original documents that contain pictures and 
printed text (Figure 4), as you often see in 
magazines or professional journals.
In the Photo & Text mode,
 the copier/printer scans 
the document and copies the text areas with the 
Text option and the photo areas with the Photo 
option. Output copies will be made using the best 
sharpness and density levels for pictures and 
charts combined with the best levels for text.
Documents to be copied using the Photo & Text 
option do not have to contain photographs and 
text. You can use the option simply to apply the 
best sharpness and density levels automatically 
for optimum colour quality on all your colour 
copies.
You can adjust the automatic recognition levels of 
text and photos. For details, refer to the 
System 
Administration Guide, 
or ask your System 
Administrator for assistance.Figure 4: Example of Photo & Text

7 Photo
The Photo option is the best selection for 
photographs or lithographs. Examples include 
photographs or lithographs (Figure 8) that portray 
people, or paintings that contain a variety of pastel 
colours.
The Photo option provides the most accurate 
colour and density copy for continuous tone 
documents that contain a wide range of densities 
from very dark to very light images.
The Photo option is also the best selection when 
true reproduction of light skin colours, light 
colours, or grey areas is important. The Photo 
option is appropriate for very high quality halftone 
documents.
1Touch the Original Type icon on the Image 
Quality tab to display the Original Type screen.
2Touch the Photo icon to display the Photo detail 
screen, illustrated in Figure 9.
3Touch the selection in the Photo Type column 
which best describes the original document:
•Halftone
Use this option for images created using a fine 
screen that varies the darkness and density of 
dots that make up the image. Examples of 
halftone images can be found in magazines 
and newspapers. 
•Photograph
Use this option when copying photographs or 
extremely fine halftones.
•Xerographic Copy
Use this option when using a Xerographic 
reproduction (copy) as the original document.

7 Graphics & Maps
Use the Graphics & Maps option to optimize the 
reproduction of detailed graphics, maps, or map-
like originals. Examples include highly technical 
drawings, histograms, pie charts, or roadmaps 
(Figure 10).
With this option, text on a light-coloured 
background is enhanced more than if the Photo 
option or the Text option were used.
Fine detail and light colours are copied very well in 
this mode. Black and white documents with fine 
details and a wide range of densities also copy 
well in this mode, although the fidelity of the 
reproduction would be better if the Photo option 
were used.
KEY POINT:When the Graphics & Maps icon is 
selected, you should specify the original size of 
any document that has dark borders using the 
Added Features tab.
1Touch the Original Type icon on the Image 
Quality tab to display the Original Type screen.
2Touch the Graphics & Maps icon, as illustrated in 
Figure 11.
