From Goose's Guide:

SC 320	Developement Bias error - Check connections on developer power pack
SC 320	Developement Bias error - Check 24v line on development drive, Drum drive and registration motors for any pinch.
SC 320	Developement Bias error - Check for any pinched harness on first 3 feed station motors.
SC 320	Developement Bias error - Developer power pack defective
SC 320	Developement Bias error - Check wire harness to Reg & dev motors- can test by unplugging CN318 and see if jams but no code.
SC 320	Developement Bias error - 24 volt short in paper feed motor 1 harness.
SC 320	Developement Bias error - check charge assy. for arcing
SC 320	Developement Bias error - disconnect CN325 on IOB, if machine 24 V int LED comes back on, check harness for first paper feed motor rubbing against fan bracket below motor.

Since you also have motors that are not running in output check, my guess is that you do not have +24 Volt from the power supply. You may have a shorted motor or solenoid causing the power supply to shut down the 24 volt output. I know it is a pain the the backside but you need to turn off the main power, disconnect all the motors and solenoids, turn the power back on and check 24 volt output from the power supply. Reconnect one motor at a time and see if it will run on in output checks. Repeat until you find the motor or solenoid that causes the pwoer supply to shut down. In my case it was one of the paper feed motors.

B234-5440.

You sure this plate disarmed is behind the machine and a small connector that is below that gives the order to the relay that deliver 24v engines forgot, no motor rotates, and if you put the engine cylinder rotate only turn the engine toner below, and you think, ohhh noooo, plug it wrong, where I start now, I broke everything, I know because I spend yesterday !!. Is the code that displays SC320.

good look.
