● ATVC Control
Transfer failure due to environmental change or deterioration of the Primary Transfer Roller or
the Secondary Transfer Roller can be prevented.
Primary Transfer ATVC
Control timing
1) At power-on
2) When replacing the Drum Unit
3) At recovery from sleep mode
4) At paper interval on a specified print basis or at last rotation
5) At environmental change
Control description
1) Monitor current value of the primary transfer DC bias is detected.
2) Optimal target current value is determined based on temperature/humidity data of the
Environment Sensor.
3) The primary transfer DC bias is determined that is to be applied to the Primary
Transfer Roller.
Secondary Transfer ATVC
Control timing
1) At power-on
2) At every print job
Control description
1) Monitor current value of the secondary transfer DC bias is detected.
2) Optimal target current value is determined based on temperature/humidity data of the
Environment Sensor and paper type.
3) The secondary transfer DC bias is determined that is to be applied to the Secondary
Transfer Roller.
