Hard-disk initialization
CAUTION A hard-disk initialization erases and reformats the printer hard disk. Perform a
hard-disk initialization only if an error code on the control panel indicates an EIO disk error.
Always try initializing the hard disk before replacing it.
NOTE Before performing a hard-disk initialization, print a menu map and a configuration
page (see
Menu map and Configuration page). Use the information on the configuration page
to reset any customer-set printer configuration values that the hard-disk initialization
procedure changes.
