Main board
1. Power down the printer. Leave the power cord plugged in to provide
a ground path for static discharges. Remove the interface cables.
2.
Loosen the main board’s two rear panel securing screws.
3. Grasp the handle and slide out the main board.
Reverse these steps to reinstall the main board. If you are replacing the main board,
swap the socketed printer ID chip and the NVRAM chip with the new board so the
printer’s settings and IP address are retained. Also swap the PostScript ROM SIMM
and the RAM SIMM(s) and print engine ROM.
