Setting the other high voltages
Description
Sets the developing bias control voltage, the transfer control voltage, and the separation control voltage or
checks the output of these voltages.
Purpose
To check the developing bias, the transfer voltage and the separation voltage or to take measures against
drop of image density or background fog.
Setting
1. Press the start key.
2. Select the item to be set.
3. Change the setting using the +/- or numeric keys.
Increasing the DEV BIAS setting makes the image darker; decreasing it makes the image lighter.
Increasing the DEV SBIAS setting makes the image darker.
Increasing the DEV DUTY setting makes the image lighter; decreasing it makes the image darker.
Increasing the TC DATA/TC DATA2 setting makes the transfer voltage higher, and decreasing it makes
the voltage lower.
Increasing the SC DATA setting makes the separation voltage higher, and decreasing it makes the volt-
age lower.
4. Press the start key. The value is set.
Completion
Press the stop key. The screen for selecting a maintenance item No. is displayed.
