    c5850 with Error Code : E000720-0001

    Good evening (In the UK),
    Has anyone here had the error E000720-0001 after fitting one of the new A1 finishers to a c58** series.
    I've now had this after fitting the new A1 booklet or staple finisher to 6 of 7 machines over the last 2 weeks.
    I know the code means that the "Finisher is incompatible with the machine it has been fitted to" but Canon UK say that the new A1 replaces the AB1 as the only finishers for the c58** series and advised that the firmware requires updating in download mode using the option to overwrite the previous firmware : I spent 5 hours at a customers today to get 2 machines working that had been delivered to them yesterday. One machine took 3 full "Download" overwrite updates and the other took 3 "Download" overwrite + 2 service mode updates using applicable firmware before they worked. So when the last one was working fully and recognised the finisher I decided to enter service mode and note which firmware had worked : It said that the last firmware download had failed!! So the way to get these working is to get a firmware installation to fail???
    Late this afternoon 3 more c58** were being made ready to deliver tomorrow but all have the same error code.
    Remove the finisher (not the buffer unit) and the machines boot normally except for a window that says "The versions of some optional devices are inappropriate for the current version of the main unit.The version of the main unit needs to be updated." Update to the latest firmware and the machine will not work with the finisher until you keep repeating the updates, using exactly the same method and firmware, until the machine gives up and concedes!!

    Regards ..... G

    Well another 4 58** to unbox and get ready for delivery today, all 5850's.
    3 were having finishers, 2 with AB2 staple finishers and 1 AB2 Booklet finisher.
    The first machine fitted with AB2 staple finisher worked with no problems at all but both the others booted up with error E000720-0001.
    Took 3x firmware updates using download mode and the same firmware on the same memory stick before error messages stopped.
    Will carry on with the last one tomorrow.
    Shame we can't get hold of Bizhubs at the moment, never had any trouble with them.

    Regards ..... Gary.
