What to do if the Lexmark C920 operator panel display is blank?
- AAnna DeanAug 28, 2025
If the operator panel display is blank or shows only diamonds, it could indicate a failed self-test. Turn the printer off, wait 10 seconds, and turn it back on. If the 'Performing Self Test' and 'Ready' messages do not appear, turn the printer off and call for service.
