7.8.2 Transfer Charging Mechanism

7.8.2.1 Outline

The following items are associated with the machine's transfer charging control system:
[1] DC bias constant current control
[2] output control to suit the environment (fuzzy control)
[3] output control at the trail edge of paper
The following shows the components associated with the transfer charging control system:
When '1', high-voltage
output is ready.
