Original Type selection and output
When you use the Original Type options of Photo
& Text or Text, the copier/printer attempts to
discriminate between text and photo or picture
areas within the original. The copier/printer then
applies the appropriate image processing to each
area. Text is reproduced at 600 lines per inch
while photos are reproduced at 200 lines or dots
per inch. Occasionally, a defect may occur where
an area is classified incorrectly and text is treated
as photo or vice versa.
To avoid this type of image quality defect for a
given original, select the Original Type options of
either Photo or Graphics and Maps. In these
modes, uniform image processing is applied to the
entire page.
NOTE: The resulting output may have a different
appearance in these modes. Some color
adjustments may be required.
If your original documents consist mostly of text or
mostly of photos, the System Administrator can
adjust the System Image Quality Image
Recognition settings. New default levels can be
set for Text & Photo Recognition and/or Text &
Photo Balance functions. The System
Administrator can select Text or Photo for Photo &
Text and Text modes.
For more information, refer to the System
Administration Guide, chapter 3, “Tools Mode.”
