The Operator Panel display does not power on (light up) and goes blank and unresponsive.




Steps Actions
1 The touch screen display may be in 'sleep' mode. Lightly touch the display and see whether the display panel lights up.
2 If the display does not respond, press OK or the Copy button and see whether the printer attempts to lights up the display.
3 If the printer comes to the 'Ready' state after powering it back on, use the operator panel on the printer to print one of the internal pages; i.e., a settings page or a demo page.

Note: If the issue occurs again, proceed with the steps below.

4 If the printer does not respond, power off the printer. Allow the printer to sit powered off for ten to 20 seconds.
5 After ten seconds or more, power the printer on again. See whether the display panel powers on correctly.

Note: Do not power the printer off and on too quickly. Doing so can cause a power issue with the display panel and create this type of issue.

6 Should powering the printer off and on not correct the issue, see if the display is readable at all.

Note: If the Main Fan is not running during power-up sequence and the Green LED is OFF, see No Power Issue.

7 If the display is blank or completely unreadable, this issue requires a service call. Please contact Lexmark Technical Support for other troubleshooting suggestions.
