8.2.4 Laser emission area
A. Main scanning direction
• The print start position in the CD direction is determined by the CD 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.
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 paper size. However, there are void areas that
are 4.2 mm/0.165" from the leading edge and 3 mm/0.118" from the trailing edge of
paper.
