Try removing the fax option. If the problem goes away, reseat or replace the MBU board on the FCU.

Longshot, but if it's every time, try disconnecting the ADF. The data cable used to cause problems on some older machines (AF1035 etc)

Also, I assume the all firmware is up to date?

Got the copier in the workshop we changed over the opps panel over with another machine and it worked.
I have taken the opps panel apart but cant see any damage etc there are a lot of boards in these units these days
but we don't have time to exchange each board in turn to narrow it down as doner copier is due to be delivered

Was this problem the original call or did it occur after being serviced? I found a few other causes for this error looking at different models, not sure if they would be relevant but worth a check. It could also be a faulty NVRAM.

Check the setting of SP5-875-001. If the setting is set to "1(OFF)", change it to "0(ON)".

We are having the same issue on a mp c6003. We have changed the bcu, imageprocessor, hard drive, controller, nvram on the controller and bcu, op panel, upgraded all the firmware. Any help appreciated

I got the same problem on a 5503. I just ordered a controller and control panel. Sometimes my machine will come to ready but only the touch screen works, none of the hard keys work. So hopefully its the panel. Anybody got any other info on this. Thanks in advance

We actually tried another control panel today from another machine that we knew worked and it fixed the problem. The control panel was the first thing we had tried before going on the wild goose chase. Must have got sent a bad one. Hope yours works the first time,
