Removing the engine ROM
To remove the engine controller ROM, first remove the paper feed roller,
referring to the previous section. Remove two screws " below. Rotate the cover
downward to gain access to the engine ROM. Note that the cover is not fully
removed because of the existence of the paper feed roller shaft.
To remove the ROM, discharge yourself by an antistatic wrist band wrapped
around your wrist (and its ground wire connected to the printer's metal chassis).
Use a ROM extractor tool to remove the engine ROM.
