Troubleshooting
Answer
Check for the following.
- Use the [Brightness] 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.
- Try pressing the [Power Save] key in the control panel. If the weekly timer has set the machine in Sleep mode,
a screen appears in the touch panel when the [Power Save] key is pressed. Enter the information indicated
in the screen to be able to use the machine during non-business hours.
- Check that the machine has been turned on by using both the [Power] (auxiliary power) key and the main
power switch.
Reminder
If no screen appears in the touch panel after the indicated items have been checked, contact your service
representative.
