System Error Codes Self-Diagnostic Errors at Power On 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 component has failed to initialize, an error code will appear on the Front Panel. INITIALIZING E Ennnn The Boot-Up error codes are hexa-decimal based numbers and correspond to bits which are explained in the following table: When multiple errors occur during the Boot-Up sequence, the error codes are added together and only one hexa-decimal figure is displayed on the Front Panel.
For example, if the NVRAM and the Power Supply fail during the Boot-Up sequence, the error code E0810 will be displayed. NVRAM (0010) + Power Supply (0800) = 0810 Each error code and it’s appropriate corrective actions are explained on the following pages.
