NOTES: • Changes in DIP switch settings (excluding switch 2-8, interface reset s ignal) are
recognized only when the printer power is turned on or when the printer is reset by using
the interface. If the DIP s witch 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 the DIP switch 2-8 is turned on while the printer power is turned on, the printer may be
reset, depending on the signal state. DIP switches s hould not be changed while the
printer power is on.
• If the print density is set to level 2 or 3, printing speed is inclined to be low speed.
• In a low power consumption, printing speed is fixed to 70 mm /s.
