w DUAL IN-LINE PACKAGE (DIP) SWITCHES In addition to the features you have just seen, your printer also
has 18 Dual In-line Package (DIP) switches to help determine the
way it handles information from your computer. Before examining
the DIP switches, turn off the printer.
To find the DIP switches, lift the cover and manually move the
carriage to the far left. On the right-hand side of the printer’s interior
you’ll see a small rubber cover. Carefully pull the cover back; the
DIP switches are directly below it. These switches are preset at the
factory, so please leave them in their present position for the time
being.
