What to do if Lexmark T630 operator panel is blank?
- GGary TuckerSep 5, 2025
If the operator panel of your Lexmark printer displays only diamonds or is blank, turn the printer off, wait about 10 seconds, and turn the printer on. After turning the printer on, 'Performing Self Test' should appear on the operator panel, and when the test is completed, 'Ready' should be displayed.
