Ricoh MP9000 SC672

You may have a fan that is speed controlled, so it wouldn't always get 12v. You may also have a secondary LV power supply going bad - If it was a loading problem the supply would "crowbar" and just shut down.

672 could be a poor connection to the op panel or any one of a bunch of things that would cause the controller not to boot. Bad Ram. Bad HDD. Loose connections. Failed Controller board. Bad System SD card. Bad or incorrect Option SD card. Loose Option Board. Failed firmware update. Angry Rampaging Gremlins.

Ricoh has something like "rescue" SD card. You can boot up your copier from this card and perform firmware update. I actually didn't use it just read about that. I've seen the same problem (672) after non proper firmware update.

"(SC672) after non proper firmware update" thats what it sounds like, some tech has hit and run... and now they called you.

I think iMind may be close to the truth!

KopyKat mentioned rebooting from a firmware SD card, this seems like a good idea.

I would prep system and engine firmware of both the new and old types, copy one set (old first?) onto an SD card and try a "door open" boot. If the machine boots to the card select both engine and system together, I have heard that if you add system / engine firmware in the wrong order you can "Freeze" the machine and get SC672 (!!!!!!!) A Ricoh tech support (helpdesk) engineer told me this, apparently he did it! they were able to overcome the problem but I don't recall how.

IF you have a tame customer with a similar machine, I suppose you could clone (borrow?) the nvram / system card and try these in your machine.

I would also look the customer straight in the eye and ask...

Did an engineer attend before you?

Was the machine working (booting up) before he arrived?

If no, what was wrong? (PCQ etc?)

If someone did attend and had the back open check for cables tucked behind the machine frame. I moved a machine with another engineer and removed the control boxes to access through a door. When we powered up the machine would not boot. I asked him 3 times if he had plugged all of the cables in (YES!!!) before a search on hands and knees revealed a cable to the left box (Small, black, below the fan????) had been tucked safely behind the main frame of the machine..... NEVER ASSUME. Don't just look for hanging cables, look for board sockets with nothing in, then for the cable that should be there, if you can't find the cable, check the P to P for the connection.

The customer complained about the error, I went onsite and turned it off, then back on and worked. The customer said that they were able to do that themselves but the machine will come up with the error after a while (a day or two). So it did. After a couple of days after I was able to boot it up and make test copies the customer called again. Now will not come back from that SC672. Monday I will try to get more info from the customer and I will let you know. Thank you for everything!

Be aware that on may Ricoh machines just switching off without following the correct shutdown procedure can be enough to fry the controller and cause SC672. By switching off and allowing the customer to do the same instead of upgrading f/ware you may have made the fault worse!

I've corrupted HDD's like that, but never trashed firmware. Ricoh engineers should be ashamed of themselves - machine won't power down if the lid is up - DUH! why even put a power button there if it's looking for a million excuses not to do its job... uh... never mind: Ricoh Engineers
