MP 6000 SC672

[tsbservice]

First thing to try is to disconnect the HDD. If it then boots, the HDD is bad.

On my Konicas when I suspect HDD I make it unset in service mode followed by physical removal of data and power cables from HDD just to make triple sure machine has no any clue about HDD
In that process I usually lose more time to remove covers over HDD than other operations.

Hello guys,

Unfortuantely the MP 6000 threw a SC672 and refuses to start. It's the usual scenario of it worked the day before just fine and today's no joy. All it does is:

• Initial Relay click when you switch the main power on
• Hangs on the "Please wait" screen for maybe 15-20s
• SC-672 error

Nothing else seems to be turning on; no fans spinning, the buzzer isn't making any sounds as it starts, the fuser isn't warming up etc. Also, the secondary power button and the LED above it don't light up.

I have removed and cleaned the DIMM sticks from the controller board with pencil eraser and some alchohol, as well as making sure the cable on the operator's panel was plugged in but no change. I also reseated 2 other DIMM sticks on a board next to the controller board, no change as well.

Finally, I disconnected the power from the HDD and still nothing.

Can you suggest me what I should try next?

Thanks.

The MP 6000 is too old now however if you want to try a firmware update feel free to contact us.

Disconnect any and all features in the back, including memory card(s), fax, HDD, etc. Yes you lose certain functions, but all you are looking for at that point is to see if that code goes away.

Disconnected both the HDD completely and then the NIC/USB card (no other expansion cards are present, such as the FAX card which could cause this cause if the jumpers are set incorrectly) but no change.

I will try to find two different sticks of RAM to try it with, but I am afraid we are headed towards replacing the controller.

Is there a possibility that someone may have removed a SD card such as the JAVA card without properly stopping JAVA? If so, the controller board is cratered.

I am 100% certain that absolutely no one has messed with the SD card, or the machine in general. The last time anyone has touched it was a couple of months ago when I did some PM work on it. It's a classic case of "it worked just fine the day before".

I just removed the cover from the SD cards, blew some air into the contacts on the motherboard (they were clean but you never know) re insterted them in the same position as they were as well, nothing again. Also I am 100% sure both sliders on the SD cards were in the original position as they where when the machine was working.

Try turning on the machine without the controller board. Then reinstall (all with the machine off of course).

Hello,

What will happen if I take the controller board out?

there may be residual electrostatic charge inhibiting the controller

Well, I removed the controller board entirely from the machine, started it up, same exact behavior before throwing a SC672 again, re installed the controller and restarted the machine to the same problem.

I also noticed that the SMD LEDs on the other boards (for example, the BCU) are lighting up, while the LEDs on the controller board (pictured - top left of the PCB) are not. This is just an observation, however.

I guess I will be ordering a replacement controller board.

When replacing it with a good used one, do I only have to transfer the NVRAM to the replacement controller board, as the manual says? If the replacement controller board, for example, comes with an older firmware version, can I just transfer the SD cards from the original board to the replacement?

check the fuses on the controller board
