B. Sequence of Operations (laser exposure system)
Figure 3-404 shows the sequence of operations for the laser exposure system.
The laser scanner motor starts to rotate as soon as the power switch is turned on and continues to
rotate at a specific speed until the power switch is turned off.
Each semiconductor laser is 00-activated as soon as the Copy Start key is pressed and is
tion period is given a delay for each color to make up for the distance between drums.
When the PWM activation for a single scan ends, the laser turns fully for BD signal detection; the next
scanning operation starts when the BD signal is generated.
