White Line Erase - Ricoh B245-62 Service Training

Setting SP4941-1 to a value other than "0" turns on white
line erase. This feature works as follows:
1. The copier scans the original.
2. The density level of each pixel is compared with its
adjacent pixels.
3. If the density level of a pixel is extremely lower then
adjacent pixels, the level is corrected. The density levels of
the adjacent pixels are considered.
When you activate the white line erase feature, the feature
works for all originals. This feature erases the white lines
of 1- through 6-pixel width (approximately, up to 0.25 mm).
The white lines that exceed this width are not erased.
When you specify "2," instead of "1," in SP 4941 1, the
feature becomes stronger and erases darker white lines
(less white lines). Note that this SP does not affect the
width of white lines to be erased.
