ATVC control
This control prevents transfer failure due to environmental change or deterioration of the
primary transfer roller or the secondary transfer roller
Primary transfer ATVC
Execution timing
1) When the power is turned ON
2) When replacing with a new drum unit
3) At recovery from sleep mode
4) At paper interval on a specified print basis or at initial rotation
5) When the environment is changed
Catuion:
The total print is counted separately between the color mode and the Bk mode. This
control is executed when the counter of either mode reaches the specified number.
Control description
1) Monitoring current value of the primary transfer DC bias is detected
2) Optimal primary charging current value is determined based on the temperature/
humidity data of Environment sensor 1.
3) The primary transfer DC bias is determined to apply to the primary transfer roller
Secondary transfer ATVC
Execution timing
At every print job
Control description
1) Monitoring current value of the secondary transfer DC bias is detected
2) Optimal primary charging current value is determined based on the temperature/
humidity data of environment sensor 2.
3) The secondary transfer DC bias is determined to apply to the secondary transfer roller
