Ricoh SP5210 sc 672 error

[COPIERMAN]

Hey everybody i had code sc672 come up and saw in manual that these were possibly bad so i had a spare unit and swap controller board not luck then op panel assy still had code. then i swap the network unit and code went away. Found out hard drive was hanging up controller board. Never display a code for hard drive being bad.


Here is what manual said.

After the machine is powered on, the communication between the
controller and the operation panel is not established, or
communication with controller is interrupted after a normal startup.
􀂃 After startup reset of the operation panel, the attention code (FDH) &
the attention acknowledge code (FEH) is not sent from the controller
within 30 seconds.
􀂃 After the controller issues a command to check the communication
line with the controller at 30 second intervals, the controller fails to
respond twice.
Controller stalled.
Controller board installed incorrectly.
Controller board defective.
Operation panel connector loose or defective.
The controller is not completely shut down when the main switch is turned
off.
Check the setting of SP5-875-001. If the setting is set to “1 (OFF)”, change
it to “0 (ON)”.

The dreaded SC672.

I've had the controller board, operations panel, laser loom, & USB to op panel, all cause this.
