Check and Adjust the LCD Brightness setting
If the display is readable, but very dim, it is possible that the screen brightness has been set too low. To check this setting, perform the following:
At the 'Ready' screen, press the Menus button in the lower right-hand corner of the touch screen. A series of menu choices should display.
Press the blue arrow next to Settings. A new set of menu choices should appear.
Press the blue arrow next to General Settings. Another set of menu choices should appear.
Look for Screen Brightness. If Screen Brightness is not showing, press the blue arrow down icon until you see the Screen Brightness setting.
The current value for Screen Brightness will be displayed. The number should be somewhere between 20 and 100.
- If the number is less than 100, press the blue arrow right icon and increase this number to 100. Press the Submit button in the lower left-hand corner to save the new value. If this corrects the issue, press the home icon button to return to the 'Ready' screen and continue using the printer as normal.
- If the Screen Brightness setting is already at 100, or if increasing the Screen Brightness setting has no effect, the printer may require a service action to correct the issue. For additional assistance, please contact Lexmark Technical Support or a local authorized service center.
Note: As a last resort before service, you can try resetting the printer back to its factory defaults. This will reset all user settings on the printer. To do this:
At the 'Ready' screen, press the Menus button.
Press the blue arrow next to Settings.
Press the blue arrow next to General Settings.
Look for Factory Defaults. If Factory Defaults is not showing, press the blue arrow down icon until you see Factory Defaults.
'Do not Restore' should now display. Press the blue arrow right icon once and change this to 'Restore Now'. Press the Submit button in the lower left-hand corner. The printer will reset all user settings back to their factory default values.
If the display panel remains dark after this, please contact Lexmark Technical Support for further assistance.
