5.1 Twin Beam Method (Laser/Scanner System)
Figure 2-7 Laser/Scanner Unit
The Laser/Scanner unit is structured with the laser driver, the scanner motor and etc. It is
controlled by the signals input from the ECU board and the SCNT board.
This machine employs the “Twin beam method” which scans two lines simultaneously with two
laser diodes in the Laser/Scanner unit.
These two diodes (LD1, LD2) emit for a single scanning so that two lines are written
simultaneously. Thus, this method enables high-resolution printing without decreasing the print
speed.
