Laser Shutter Mechanism

should it be inadvertently emitted, from leaking when the IU is removed from the
machine.

Laser emission area

A. Main scan direction
• The print start position in the FD direction is determined by the FD Print Start signal
(HSYNC) that is output from the MFBS Board (MFBS) and the width of the paper.
• The laser emission area is determined by the paper size. The area of 4 mm on both
edges of the paper is, however, the void image area.
