Selects the strength of the MTF coefficient filter
setting selected with SP4903 039 to adjust the
clarity of edges of images copied in the
Text/Photo mode and enlarged in the range 25%
to 64%.
A higher setting increases the strength of the
effect, and a lower setting decreases the effect.
While a higher setting can improve the clarity of
text and thin lines, a very high setting can
increase the incidence of moiré.

Filter Adj.: Text/Photo
(Edge Det.) 25-64%
Selects the MTF filter coefficient of the edge
detection level of the filter setting selected with
SP4903 039 to adjust the clarity of edges in
images copied in the Text/Photo mode and
enlarged in the range 25% to 64%. A lower
setting increases the number of edges detected,
and a higher setting decreases the number of
edges detected.
•
A higher setting affects the density of lines
with a steep slope and to a lesser degree
affects the density of gently sloping lines.
•
Areas other than sloping lines are not
affected by this adjustment.
•
If edge detection is set high, then the range
of edge detection is expanded to include any
background.
