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.
3. Attach the new NVRAM so the curvature of the white line on the board
¬
matches the curvature of
the indentation on the NVRAM chip.
The table below lists the counters and other items that are cleared as a result of replacing the controller
board with a new controller board and new NVRAM, or replacing only the NVRAM. Some items require
manual resetting, and others do not require resetting.
