	Setting the I/O timeout
	I/O Timeout sets the number of seconds that the printer waits to
	receive additional data from the computer before switching I/O ports.
	The default setting for the printer is 15 seconds.

Note	Setting the I/O Timeout too high may cause a single I/O port to remain
	active and prohibit data from being received through other ports.
	Setting I/O Timeout too low may result in missing characters,
	out-of-order print jobs, or other print problems.

1Press MENU until I/O MENU displays.

2Press ITEM until I/O TIMEOUT displays.

3Press VALUE to increase or decrease the I/O Timeout value. Holding the key down will change the value more quickly.

4Press SELECT to save the setting.
