2-2 Operation

2-2-1 Setting the DIP switches

The DIP switches are located on the bottom of the printer. The DIP switches are used to set the printer to perform various functions. Follow these when changing DIP switches setting :

1.Turn the printer power switch off.

2.Remove the screw on the bottom of the printer and open the bracket.

3.Flip the DIP switches using tweezers or another marrow-ended tool. Switches are in when up and off when off down in the Figure 3-12.

4.The new setting takes effect when you turn on the printer.

Note : Always change DIP switch settings only when the printer is turned off. Change made with the power on have no effect and then on again.
