■ Primary Transfer Control
Primary Transfer ATVC
Purpose
The transfer voltage required to obtain the target transfer current value is set in order to prevent transfer failure due to
environmental changes.
Control description
1. The current value of the primary transfer DC bias is detected.
2. Optimal target current value is determined based on the temperature/humidity data of the Environment Sensor (UN27).
3. The primary transfer DC bias to be applied to the Primary Transfer Roller is determined.
Execution timing
The execution timing for this control depends on the control timing, adjustment timing, and the combination of conditions.
Control timing Adjustment timing Condition
Automatic adjust-
ment by the output
of a specific number
of prints When a job starts Every 100 accumulated images
When sudden environmental changes are detected by the Environment Sensor
At paper interval Every 100 accumulated images
Control at job comple-
tion Every 500 accumulated images (only in high temperature and high humidity envi-
ronments)
Every 1000 accumulated images
At startup At power-on At normal startup
If 8 hours or more have elapsed in high-speed startup mode
At recovery from sleep
mode If 8 hours or more have elapsed in sleep mode
Automatic adjust-

Primary Transfer Bias Control
Purpose
To apply current to the Primary Transfer Roller
Control description
The primary transfer bias for each color (Y/M/C/Bk) is generated by the Primary Transfer High Voltage PCB (UN02) and
applied to the Primary Transfer Roller.
The primary transfer bias value is determined by the primary transfer ATVC control.
