Setting the other high voltages
Description
Changes the developing bias voltage and transfer/separation voltage.
Purpose
To check the developing bias and the transfer/separation voltage or to take measures against drop of image
density or background fog.
Method
1. Press the start key. The screen for selecting an item is displayed.
2. Select the item to be set using the up/down cursor keys.
3. Press the start key. The screen for executing each item is displayed.
Setting the developing bias
1. Select the item to be set using the up/down cursor keys.
2. Change the setting using the left/right cursor keys.
Increasing the BIAS C/P setting makes the image lighter; decreasing it makes the image darker.
Increasing the DUTY C/P setting makes the image lighter; decreasing it makes the image darker.
3. Press the start key. The value is set.
Setting the transfer voltage
1. Select the item to be set using the up/down cursor keys.
2. Change the setting using the left/right cursor keys.
3. Press the start key. The value is set.
Setting the separation voltage
1. Select the item to be set using the up/down cursor keys.
2. Change the setting using the left/right cursor keys.
3. 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.
1. Press the interrupt key. The machine enters the interrupt copy mode.
2. Set the original and press the strat key.
To return to the screen for setting, press the interrupt key.
Completion
Press the stop/clear key at the screen for selecting an item. The screen for maintenance item No. is dis-
played.
Maintenance
item No.
