I am looking for the firmware or system software for Canon irc5800. I need this as I am trying to upgrade the machine with fax function. I bought a second hand 3G fax board , fitted in the machine and get the machine turned on it returned error code E000674-0001. i turn the machine off and disconnected the wiring between the machine and the fax board . The machine powered well. I did try Canon but it seemed they did not want to give it to me though they did not actually said so and I think they would ask for $$$$$$..... I looked at the service manual and realized I needed SST v1.8 + and the system software loaded in the SST to do the upgrade. I have managed to find SST v 4.11 and 2.01 on the net but so far my search for the firmware seems to be fruitless. Would someone kindly help with the files ? This would be much appreciated.
