Setting the DIP Switches

The printer has two sets of DIP (Dual Mine Package) switches
located on the back panel. By changing the settings of these
switches, you can control various printer features, such as the
character set and page length. The new settings become effective
when you turn on, reset, or initialize the printer.

Changing a DIP Switch Setting

To change a DIP switch setting, follow these steps:

1.

Turn off the printer.

2.

Locate the DIP switches on the back of the printer.

3. Use a pointed object, such as a pen, to change the DIP switch

settings. A DIP switch is on when it is up, and off when it is
down.

The new DIP switch settings take effect when you turn the printer on.
