Bought this low meter off lease machine and have a buyer for it. When getting ready for delivery I noticed it had really old F/W in it so I tried to update by doing in steps until latest F/W, but never got past the 1st new F/W because MFP came up N.G. All other items, ADF, Printer, etc loaded F/W and completed with no problems. I tried 5 different USB sticks that have worked in other 4 series.
Now when booting up I get message "invalid firmware" etc, WITHOUT USB stick inserted.
Only way I could get machine to work is buy leaving USB service port open so it don't block the sensor. After checking in serv mode F/W is still the same and all counts, serial #, etc have not changed. Machine works fine as long as USB service port cover is open without USB inserted when booting up.
Does have blue dot by serial #.
So at this point I will have to deliver with the old original C8 F/W and USB service port cover removed.
Anyone ever see one of these 4 series where you had to leave USB port cover open for it to work?
Any help appreciated
Thanks in advance
