4100 firmware dimm update

[stumpy25]

HP 4100n, receiving 49.FF04 error code. Have removed all DIMMs and EIOs. Removed and replaced a current Firmware DIMM, and replaced the Formatter card. What next? Any ideas?

This shouldn't happen, 49.xx is an error that is usually cured by replacing the Formatter board and DIMM's, if you have swapped both therre might be a problem with the board connection in the printer.
