Check this procedure and tell me the results:

[F070] Communication error between System-CPU and Engine-CPU
(1) Check the version of the system ROM on the SYS board.
(2) Check the version of the engine ROM on the LGC board.
(3) Check if the connector CN423 on the IMG board and the connector CN354 on the LGC board
are completely inserted.
(4) Check if the connector pin between the IMG board (connector CN423) and the LGC board (connector
CN354) is disconnected.
(5) Check if the connector CN422 on the IMG board and the connector CN127 on the SYS board are
completely inserted.
(6) Check if the connector pin between the IMG board (connector CN422) and the SYS board (connector
CN127) is disconnected.
(7) Check if the conductor patterns on the IMG board, LGC board and SYS board are short circuited
or open circuited.
(8) Replace the LGC board if no problem is found in steps from (1) to (7) above.
(9) If the problem is not corrected with the replacement of the LGC board, reinstall the removed LGC
board and replace the SYS board.
(10) If the problem is still not corrected with the replacement of the SYS board, reinstall the removed
SYS board and replace the IMG board.

well the boards are fine and all connectors i had unpluged and then pluged back in. i strongly belive that its the firmware because our it guy tried to get it to print because before it wasent set up to print only copy. i have tried a few things in [0][8] mode.. i read a thread that some one had the same problem and he just upgraded to the right firmware and it solved his problem.
