Ricoh MP C2500 Error Code SC672 on Startup.

**davel** · 09-13-2021

Machine is very old, only hope is get a controller from a parts machine but I assume you are not an experienced tech so may be you need to buy a replacement machine.

Did you remove HDD and Ram at the same time? Not a good idea afaik..

In case the unit has a java/vm card you can try and remove it, too.

Can any one help me to remove this error? it is also not going to service mode. just stuck on startup screen.

try to disconnect and reconnect the controller and its connectors, try to turn on the machine with the hdd disconnected, but it is easy for it to be the failed controller

Thank you All for your Great help. I Tried things that you mentioned above but problem was the same. but Suddenly I saw a switch board (Picture is attached) that have a 8 switches. all are upside but switch number 1 and 8 was down. I turn them up one by one. now the situation is that when move both switch up(1&8) the same error comes SC672. But when I move down the switch number 1 only print start and then give a new Error SC819 (Picture is attached). and I like to tell you that at the start of problem it starts with this same error (SC819). Sc672 come letter. now its back to SC819. Please guide me.

SC819 is usually a HDD issue so you could try replacing that you can use pretty much any 2.5” but since you only got that error after moving a SW it could be caused by that.

Dear Friends,
I put back every thing to its place and only remove a Big SD Memory Card on the back of the machine. and machine take a long time on welcome screen and turned on and I tried to make a copy it was working fine. buts it was not going to printer and scanner mode. I tried 3 to 4 time by restarting the machine. every time it take long time to start. but not going to printer and scanner options. then I just leave it for a while. then I just put the USB cable in the printer to check didn't connect to my laptop. then I saw that screen and every thing is off. and only power light in on. then I tried to restart it. but every time only Power light is turning on nothing else. Can you tell me what is the problem.

Hi

We're the switches on the controller board? Switch 1 dictates booting from flash memory if off or SD card when on.

Switch 2 to 8 should not be changed.

Did you change these with the machine powered on?

The more you do without knowing what the heck you are doing the worse it will become. Put the old thing out of its misery and update to a newer model.

I Always turn power off before changing any thing. but once by mistake I didn't off the machine and change switch No. 8.
