7 Troubleshooting
7-4 bizhub C200 (Phase2)
Why does no screen appear in the touch panel?
If no operation is performed for a specified length of time, the touch panel goes off and the machine
automatically enters a mode where it conserves energy.
Answer
Check for the following.
- Use the [Contrast] dial in the control panel to adjust the brightness of the screen in the touch panel.
- Touch the touch panel. There is no problem if the touch panel lights up. When the machine is in Power
Save mode, touching the touch panel or pressing a key in the control panel cancels Power Save mode.
Opening the ADF or original cover also cancels Power Save mode.
- Check that the machine has been turned on by using both the sub power switch and the main power
switch.
