That specific error message is not posted in the Service Manual, however there are a few others that may be helpful.


99.00.07 Upgrade not performed error reading upgrade


A remote firmware upgrade (RFU) was not performed.

Unexpected read error when reading rest of header.

Recommended action

1. Download the RFU file and attempt the upgrade again.

2. If the error persists, replace the hard disk.




Firmware installation error

Recommended action

Reload the firmware.



Basically you should try to reflash the firmware.  If that doesnt work then you may have bricked your printer and shoudl consider warranty support or replacement.  Good luck!
