Line Width Correction - Ricoh SP5 Series Service Manual

2.3.13 LINE WIDTH CORRECTION

This function is effective only in generation copy mode.
Usually, lines will bulge in the main scan direction as a result of the
negative/positive development system that is used in this model. So, pixels on
edges between black and white areas are compared with adjacent pixels, and if the
pixel is on a line, the line thickness will be reduced.
The line width correction is done in the IPU chip.
The line width correction type can be selected with SP4904-6.
