Symptom Cause Action
Operator panel shows
only diamonds or is
blank. The printer self test failed. Turn the printer off, wait about 10 seconds, and turn the printer
on.
The clock appears on the operator panel. When the test is
completed,
Ready appears.
If the messages do not appear, turn the printer off. For technical
support, contact the Lexmark Customer Support Center at
http://support.lexmark.com.
Menu settings changed
from the operator panel
have no effect. Settings in the software
application, the printer
driver, or the printer
utilities are overriding the
settings made from the
operator panel. Change the menu settings from the printer driver, the printer
utilities, or the software application instead of the operator panel.
Disable the settings in the printer driver, the printer utilities, or the
software application so the settings from the operator panel can
be changed.
LCD is too light or too
dark. The LCD Contrast setting
is not adjusted. Adjust the LCD Contrast setting. See Adjusting operator
panel contrast.
