Using the Power-up Sequence to Troubleshoot
When the Printer is powered up, it performs the Boot-UP sequence which initializes the major components
of the Printer. If for some reason the Boot-Up sequence fails because a components has failed to initialize,
the following explanations will help you to locate the failing component.
4Front Panel

rectly connected between the Front Panel and the Interconnect
PCA.
• Perform the Front Panel service test

Hard Disk Drive damaged
or missing
• Remove the Main PCA Cover and (with the Printer switched On)
check that the HDD is spinning (you should feel it spinning when
you touch it or at least hear it spinning). If the HDD is not spin-

⇒ See page 452.
• Make sure that ALL cables connected to the HDD are not dam-
aged and are connected correctly.
• Replace the HDD
