2. Engine down detected suddenly during power on and warm up.

IBCU installation incorrect
IBCU defective
Sudden communication reset

You should be able to reset it by powering the copier off completely with the switch on the front, not the control panel, wait 15 -30 seconds, and power it back up again.

which model machine???

SC670 applies to many different Xerox machines,, but i can't help you without the relevant model

PLEASE ENTER THE SP MODE AND THEN PRESS 5801 TO ENTER THE FRMATTING MODE .
SELECT FORMAT HDD AND EXECUTEE.
THANK YOU.

The code is engine start up error "replace engine board, sorry...

sc670 is an engine startup error. A lot of times if you reset the copier (turn it off with the orange switch on the left side of the front cover, then turn it back on) the error will go away. If it doesn't the BCU board may need to be replaced.

Here is the actual code: SC670 mistake Engine Response.

It’s always a good idea to ask for a fix along with a question about an error code...
so what’s going on is no response from the BCU at power on; which means when the main power is turned on or the machine starts warming up from energy-saving mode, the controller does not receive a command signal from the BCU. So that could mean a

• Loose connection
• Defective controller
• Defective BCU

You can try these things:

1. Turn the main switch off and on.
2. Check the connection between the
BCU and controller.
3. Replace the controller.
4. Replace the BCU.
After replacing the BCU or controller, remove the NVRAM on the old board and put it on the new one.
If you have not worked on these units before you may need the help of a shop.

is there any sensors on the adf unit, if so is the paper being feed into the adf unit, there might be a bad/defective sensor, try placing a letter size sheet on the document glass and make a copy, if it copies you have a problem with the adf, and it needs to be serviced
