Here are steps to troubleshoot when the touch screen display does not respond or light up after entering 'Sleep' mode on a Lexmark X651, X652, X654, X656, or X658 printer.

Issue description

Solution

The touch screen display may be in 'sleep' mode. Lightly touch the display and see if the display panel lights up.

If the display does not respond, press the Copy
button and see if the printer attempts to make a copy.

If the printer attempts to make a copy, updating the Universal Integrated Circuit Card (UICC
) code may correct the issue. the-touch-screen-display-does-not-respond-or-light.html#the-touch-screen-display-does-not-respond-or-light-up-after-sleep-mode_SO4762 for instructions.

If the printer does not respond, power off the printer. Allow the printer to sit powered off for 30 seconds or longer.

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.

After 30 seconds or more, power the printer on again. See if the display panel powers on correctly. If the display panel powers on correctly.

IMPORTANT!
Do not power the printer off and on too quickly. Doing so can cause a power issue with the display panel and create this issue.

If the display panel powers on correctly, the Universal Integrated Circuit Card (UICC) code
on the device may need to be updated. See the instructions below.

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.
