6.3.2.3 Not Recoverable Errors
When an error of this kind occurs, the printer is halted and enters in error state.
All these errors cannot be resetted through specific actions and required the powering-off
of the printer.
Typically all these problems appears if an internal error in the BOOSTRAP or normal
operation phases is detected.
If after powering-on the printer the problem appears again, contact your nearest Digital
Customer Service Center.
In the BOOSTRAP phase the following messages can be displayed.
If one of these messages appears, the BOOSTRAP phase is not positively ended and,
consequently, the hardware resources of the printer are not initialized.
