DP-MB545/537/536 series

1. Function

There are 16 LEDs as below circuit for cleaning the OPC surface after printing.
This purpose is to prevent occurrence of the ghost.
These LEDs turn on under printing only.

2. Circuit diagram

3. Circuit explanation

SoC(IC300) control these LEDs by ERLED_CTL port(K1). When the ERLED_CTL port becomes high, LEDs turn ON.
Q500_Ic current is about 29mA.(Current of each LED is about 14.5mA)
R520, R521, R529 and Q500 are for fix the current.
