Replacing the print engine ROM

Locate the print engine ROM.

Note

Some products may use a standard ROM IC chip while others may
use an adaptor circuit board. Either part type can be substituted for
the other on this main board.

Insert the IC removal tool between the ROM (or adaptor board ROM)
and the socket.

GENTLY

remove the old part by prying upward, being

careful to not damage the main board. When the near end of the part
begins to lift from the socket, gently lift the other end of the part with
your fingers to prevent damage to the ROM’s pins.

Install the new engine ROM (it can be identified by the number
163-0822-00 or 671-3938-00 printed on it). Check for proper
orientation and alignment of the pins; pin 1 should be oriented toward
the network card end of the main board. Press the ROM firmly into its
socket.

Note

Pin 1 end of the adaptor board is identified by the square pads on the
upper surface of the board; alternately, the pin 1 end can be identified
by the notch in the pin array on the bottom-side of the board.

10.

Reinstall the main board into the printer.
