U101
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.
Method
1. Enter the maintenance mode and press the cursor up/down keys to display [U101].
2. Press the cursor right key to display the submenu screen.
3. Press the cursor up/down keys to select an item for which the preset value is to be changed.
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 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 OK key. [ _ ] will blink.
5. Press the cursor left/right keys to move [ _ ] to the digit position at which the value is to be changed and
press the cursor up/down keys to change the preset value.
6. Press the OK key. The value is set.
To keep the preset value, press the CANCEL key.
Maintenance
item No.
