If the control board is being replaced:
1. Pull the NVRAM from the control board removed from the printer.
2. Install the NVRAM on the new control board.
Attach the new NVRAM so the curvature of the white line on the board [1]
matches the curvature of the indentation [2] on the NVRAM chip.
3. Install the new control board in the printer.
The table below lists the counters and other items that are cleared as a result of replacing
the controller board and NVRAM or replacing only the NVRAM. Some items require
