main board must be taken out of the printer. Protect the electronics by taking these
precautions:

metal object to discharge yourself of static electricity. While doing the
work, it is recommended that you wear an antistatic wrist strap.
Caution Touch the main board only by the edge.
Caution Be sure to remove the memory card first if inserted in the printer’s
memory card slot.
Refer to chapter 2 and remove the main board out of the printer.
Locate the jumper connector.
To change the serial protocol from RS-232C to RS-422A, for example, carefully
remove the jumper connector from the interface card, and reconnect to the pin posi-
