It's hard to say. You could have a defective board. One of the following:

Printer control board (PRCB)
Image processing board (IPB)
Program of overall control board (OACB)

Try to recheck all of the connectors.

You could start by re-seating or replacing the memory sticks

Does the error come up immediately does the machine predrive
what I am trying to determine what stage of the boot proccess the machine give this code .If it is early while the sub power switch is turn on then it could most likely be the ORCB board if it 's a couple of seconds later it could be the PRCB
The service manual lays mentions these board pertianing to this error code
