(Setting the reproduction (text recognition level) of text on
dots of a document printed by the printer)
This function is effective especially when copying a document that
is printed by an inkjet printer or a laser printer in the automatic
color copy mode.
Some inkjet printers and laser printers express gradations with the
thickness of lines. In that case, line images may be erroneously
recognized as text images.
When recognized as text images, the area is printed with sharp
edges and high contrast, losing gradations. In addition, dirt may
appear on the print.
To cope with this problem, the text (edge) recognition level can be
adjusted.
1) Select the SEG mode.
2) Select the setting mode B with the scroll key.
3) Enter the set value with the 10-key and press the [OK] key to
set the entered value.
(Filter setting for high lpi (line per inch) images in the Text
mode and the Printed Photo mode)
A suitable filer can be selected in the color auto (Text, Printed
Photo) mode and when the document includes high lpi images.
If moire is found, adjust the set value to 2 in order to reduce sharp-
ness and reduce moire.
1) Select the SEG mode.
2) Select Mode C with the scroll key.
3) Enter a set value with the 10-key and press the [OK] key to set
the entered value.
(Filter setting for low lpi (line per inch) images in the Text
mode and the Printed Photo mode)
A suitable filer can be selected in the color auto (Text, Printed
Photo) mode and when the document includes low lpi images.
If moire is found, adjust the set value to 2 in order to reduce sharp-
ness and reduce moire.
