When interface pin 6 is used as the reset signal, the printer goes to the reset status when the RS-
232C level goes to the MARK status. When interface pin 25 is used as the reset signal, the printer
is reset when the RS-232C level and SPACE TTL level go HIGH.
• The DIP switch settings other than 2-7 and 2-8 are only valid when the power is turned on and
when the interface is reset. After this, changing a setting does not change the function.
Turning DIP switch 2-7 or 2-8 On while the power is on will cause the printer to be reset, due to
the signal line status. Therefore, it is recommended that these switches are not operated while
the power is on.
• Setting the print density to level 3 or level 4 has a tendency to reduce the print speed.
