I would suggest following the steps in the knowledgebase solution in the online support for power cycling both the machine and the Fiery. http://www.support.xerox.com/support/DC242_DC252_DC260/support/en_US.html?objGUID=32657
I hope this helps.
Thanks for using the Forum
MY DC 242 WILL NOT START
THE SCREEN WILL START THEN CUT OFF BUT FIERY WILL BE ON.
