C0630 = DMA problem
?DMA transmission of compressed,
decompressed, rotated, relocated or
blanked-out image data does not
complete within the specified period
of time.
Solution: Replace the main PCB and check for correct operation.
I would suggest to go to maintenance mode and do U906 reset. It should clear if not than , check also Memory module, if you can swap it from another machine.
