Laser emission area
A. Main scan direction (CD)
• The print start position in the CD direction is determined by the CD print start signal
(HSY
N
C) that is output from the printer control board and the width of the media.
• The laser emission area is determined by the media size. However, there is
a 4.0 mm
wide void area on both the both edges of the media.
B. Sub scan direction (FD)
• The print start position in the FD direction is determined by the FD print start signal
(TOD) that is output from the printer control board and the length of the media.
• The laser emission area is determined by the media size. However, there is
a 4.0 mm
wide void area on both the leading and trailing edges of the media.
