[LD Pulse] LD Pulse Area Correction (Color, Area) FA
2150
Adjusts the area correction value for color shift comparing with black. The main scan
(320 mm) is divided into 12 areas. The area 1 is at front side of the machine (left
side of an image) and area 12 is at rear side of the machine (right side of an image).
When you decrease this value, an image shifts to the left side on a print.
When you increase this value, an image shifts to the right side on a print.
