Hello and thank you for choosing JA for your support needs. Sorry for the issue, please try this work around and let me know of your results.

Please do this. Unplug the printer...wait 90 seconds... Then push and hold the power button in and plug the machine back in... Do not let go of the power button until you see the screen flash the OX code.... Please wait 15 more seconds and release.... The system should go into normal start up mode.
