Write section 7.2.3 Laser emission timing • When a ready signal is detected after the lapse of a given period of time after the print cycle has been started, a laser ON signal is output from the MFP board. • The laser ON signal triggers the firing of each laser light, which illuminates the index board via the polygon mirror, G1 lens, separation mirror (K), and SOS lens. This generates an SOS signal. • This SOS (Start of Scan) signal unifies the timing at which the laser lights are irradiated for each main scan line. • The SOS signal is generated only from the K laser light. For the other colors, the emission timing is determined with reference to K. 7.2.4 Laser emission area A. Main scan direction (FD) • The print start position in the FD direction is determined by the FD print start signal (HSYNC) that is output from the MFP board and the width of the media. • The laser emission area is determined by the media size. However, there is a 4 mm/ 0.157 inch wide void area on both the both edges of the media. B. Sub scan direction (CD) • The print start position in the CD direction is determined by the CD print start signal (TOD) that is output from the MFP board and the length of the media. However, there is a 4 mm/0.157 inch wide void area on both edges of the media. • The laser emission area is determined by the media size. However, there is a 4 mm/ 0.157 inch wide void area on both the leading and trailing edges of the media. Void width: 4 mm/0.157 inch Void width: 4 mm/0.157 inch Void width: 4 mm/0.157 inch Composition/Operation Void width: 4 mm/0.157 inch 4138to2595c0 13

7.2.3
Laser emission timing
•
When a ready signal is detected after the lapse of a given period of time after the print
cycle has been started, a laser ON signal is output from the MFP board.
•
The laser ON signal triggers the firing of each laser light, which illuminates the index
board via the polygon mirror, G1 lens, separation mirror (K), and SOS lens. This gener-
ates an SOS signal.
•
This SOS (Start of Scan) signal unifies the timing at which the laser lights are irradiated
for each main scan line.
•
The SOS signal is generated only from the K laser light. For the other colors, the emis-
sion timing is determined with reference to K.
7.2.4
Laser emission area
A.
Main scan direction (FD)
•
The print start position in the FD direction is determined by the FD print start signal
(HSYNC) that is output from the MFP board and the width of the media.
•
The laser emission area is determined by the media size. However, there is a 4 mm/
0.157 inch wide void area on both the both edges of the media.
B.
Sub scan direction (CD)
•
The print start position in the CD direction is determined by the CD print start signal
(TOD) that is output from the MFP board and the length of the media. However, there is a
4 mm/0.157 inch wide void area on both edges of the media.
•
The laser emission area is determined by the media size. However, there is a 4 mm/
0.157 inch wide void area on both the leading and trailing edges of the media.
