Maintenance
Description
item No.
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 or change the developing bias, the transfer voltage, and the separation voltage.
Method
Press the start key. The screen for selecting an item is displayed.
Display Description
DEV BIAS SET Setting of developing bias control voltage
TC SET Setting and output check of transfer control voltage
AC SET Setting of separation control voltage
Setting: developing bias control voltage
1. Press the DEV BIAS SET on the touch panel of the screen for selecting an item.
2. Select an item to be set.
Display Description Setting range Initial setting
DB DATA Developing bias step control final voltage 0 to 255 207
DB DATA2 Developing bias step control initial voltage 0 to 255 52
3. Change the setting using the cursor up/down keys.
Increasing the setting makes the image darker; decreasing it makes the image lighter.
4. Press the start key. The value is set.
Setting: transfer bias control voltage
1. Press the TC SET on the touch panel of the screen for selecting an item.
2. Select an item to be set.
Display Description Setting range Initial setting
TC DATA Transfer control voltage for simplex copying 0 to 255 210
TC DATA (DUP) Transfer control voltage for duplex copying 0 to 255 210
TC ON Transfer voltage output ON – –
3. Change the setting using the cursor up/down keys.
Increasing the setting makes the transfer voltage higher, and decreasing it makes the voltage lower.
Press the TC ON on the touch panel. The currently set transfer voltage is output. To stop the transfer
voltage output, press the stop/clear key.
4. Press the start key. The value is set.
Setting: separation bias control voltage
1. Press the AC SET on the touch panel of the screen for selecting an item.
2. Select an item to be set.
Display Description Setting range Initial setting
AC DATA separation control voltage for simplex copying 0 to 255 200
AC DATA (DUP) separation control voltage for duplex copying 0 to 255 230
3. Change the setting using the cursor up/down keys.
Increasing the setting makes the separation voltage higher, and decreasing it makes the voltage lower.
4. Press the start key. The value is set.
Interrupt copy mode
While this maintenance item is being performed, copying from an original can be made in interrupt copy mode.
Completion
Press the stop/clear key at the screen for selecting an item. The screen for maintenance item No. is displayed.
