Replace BCU board - no change.
Power supply?

Re: SC542 ricoh 3228c

Take a close look inside the fuser connectors - these are well known for "biting" paper jams if the customer pulls out the fuser and pushed it back in the machine but didn't removed the jam that might be hidden behind the fuser.

Almost 100% sure that some piece of paper is blocking the fusing unit connector inside the machine, like Gift said.

thanks guys, I had it happened to me before, this time - no dice.

Re: SC542 ricoh 3228c

Sometimes one might have to look at it twice if a bit of paper stucks in there in a bad angle. I can't imagine it's something else if you already replaced the entire fuser unit. Speaking of that - did you try to use one of the CL7200? You can do that but not without a wiring modification IIRC.

Btw: In case there's a contact issue with the thermistors you should get very bad readings if you check the fuser roller temperature within the service program.

Re: SC542 ricoh 3228c

Thanks guys. It was as simple as system lock - it was turned on. Never seen that before, but after entering user tools/system settings - there she was, laying low in full view; it was the only option. It's all good.

Re: SC542 ricoh 3228c

Sorry, I don't get that - what was the problem? Never heard of a system lock or any end user setting that affects fuser sc code behaviours so it would be interesting to know how one can re-produce that.

Same here, that sounds like fluke of the week to me.

Re: SC542 ricoh 3228c

After rereading the original post, it appears that service mode was locked out in User Tools and he couldn't reset the SC because he couldn't access it- not that he reset it but the code wouldn't clear.

Replaced fuser unit.
Code can't be reset through SP mode. < this can be interpreted 2 different ways, if he had stated SP mode couldn't be accessed then we would have known the problem early on.
Replace BCU board - no change.
Power supply?

Yep...why the hell you'd bother with the BCU BEFORE attempting to gain access to the SP is beyond me...arse up troubleshooting

The reason is quite simple as I posted when I found out. As a few others here have confirmed, we didn't know there is such a thing that system locked. You CAN'T access SP mode when system is locked. Hence replacing BCU - plus customer had a lot of power problems, static and bad voltage as I found out when the usual fuser reset procedure didn't work. Now does it make a little closer vs 'beyond me'? Did you know there was a critter like this? I sure didn't.

What we are trying to get at is the wording in your original post left the impression that you could access the SP code but resetting it wouldn't clear the fault. This is a case where precise wording is important, ie. "I can't access Service Mode". Oh well, we live and learn. No harm, no foul (except the expense of the BCU board for you).

*It should say "Service Mode Lock", not "System Lock". I remember it from training, but not everyone who works on something is necessarily trained on it.
