Replace the Base controller
If it is clear that an error can only be solved by replacing the motherboard a new base controller
can be ordered as a service part. This controller has all the hardware in it without the extra
boards that are added to make it a PRISMAsync controller (DDI board, AUX Control Board,
Ethernet Board, 22W1 Harness).
NOTE
When servicing components of the PRISMAsync for imagePRESS C800 Series always wear a
grounded strap around your wrist, to avoid electrostatic discharge that will harm your
equipment.
Perform the following actions to exchange the controller:
Step Action

2 Remove extra boards
• Remove the following boards:
• DDI board (See:

• AUX Control board (See:

Check if you need a newer version of the AUX control board. (See conditions
