DC Controller Board (page 1 of 5)
First Remove the I/O controller board, front door, top cover, left cover, rear
cover, rear shield plate, status panel bottom cover, and I/O interconnect
shield.
Important: The DC controller board stores important information
about consumables and other customer-specific parameters. If you are
replacing the DC controller board, you must first download these
parameters from the old board so that you can upload them to the
replacement board. For more information, see “Diagnostic Utility” in
Chapter 2.
