Before You Change the Switch Settings

For DIP switch changes to have effect, you must first turn off the printer.

Be sure to treat the switches gently. Avoid touching them with your hands. Static charges, dirt and oil from your fingers can harm the switches.

The switches are most easily changed with a pointed object such as a small screwdriver or ball point pen.

On each switch panel is an arrow and the word ON to indicate the ON position. You can also remember the settings on the interface switches as being ON when up and OFF when down.

Warning:

The two sets of switches described here are the only ones you should attempt to change. Do not attempt to make changes to any other switches on the main circuit board; changing the setting of the other DIP switches may result in improper operation or damage to the printer.

How the DIP switches are identified

Each switch panel contains several switches, each with its own identifying number.

Open the hinged front dust cover and look inside. The column DIP switch panel is on the right. We’ll refer to these four switches as SW-1 to SW-4.

Now look at the two groups of switches on the interface on the back of the printer. These are referred to as Panel 1 (with four switches) and Panel 2 (with eight). To identify these switches, we’ll first use the panel number and then the switch number. Thus, the second switch on Panel 1 is SWl-2, the third switch on Panel 2 is SW2-3, and so on.

Column DIP Switch Panel

The first three switches of this panel (SW-l to SW-3) set the width and shape of the printing area for a page. The fourth switch is used with the optional cut sheet feeder.

Table D-l shows the DIP switch settings necessary to obtain the size and shape of the different printing areas that are possible.

Set these switches according to your needs.
