Notes:
•
Changes in DIP switch settings (excluding switch 2-8 interface reset signal) are
recognized only when the printer power is turned on or when the printer is
reset by using the interface. If the DIP switch setting is changed after the
printer power is turned on, the change does not take effect until the printer is
turned on again or is reset.
•
If you turn on DIP switch 2-8 while the printer is turned on, the printer may be
reset, depending on the signal state. DIP switches should not be changed
while the printer power is on.
