Laser emission area

A. Main scanning direction
• The print start position in the main scanning direction is determined by the main scan-
ning print start signal (/HSYNC) that is output from the printer control board and the
width of the paper.
• The laser emission area is determined by the paper size. The area of 3 mm/0.118 inch
on both edges of the paper is, however, the void image area. (With the long size paper,
the area of 4.2 mm/0.165 inches on both edges of paper is the void image area.)
B. Sub scanning direction
• The print start position in the sub scanning direction is determined by the image write
start signal (/TOD) that is output from the printer control board and the length of the
paper.
• The laser emission area is determined by the paper size. However, there are void areas
that are 4.2 mm/0.165 inch from the leading edge and 3 mm/0.118 inch from the trailing
edge of paper. (With the long size paper, the area of 4.2 mm/0.165 inches on both the
leading and trailing edges of paper is the void image area.)
