Vertical Black Line Correction

This section describes how to select a setting to correct vertical black lines.
SP4904 5 (Special Text Density) adjusts the overall intensity of the image to
eliminate vertical black lines in originals caused by documents scanned on a copy
machine with dirty optics.
SP Mode
SP4904 5 Special Text Density
Normally, the default setting (0) leaves this feature switched off.
Select a higher setting to increase the effect or a lower setting to decrease the
effect. High density vertical black lines may require a higher setting, but a higher
setting could cause the overall density of the copy to lower, or could cause low
density areas to drop out completely.
NOTE: Generally, this SP code corrects most low density vertical black lines but
may not be able to correct extremely dark or wide black lines.
