2. Configuration Operation Manual
Each switch is an eight position “toggle” switch. The ON position
is always to the bottom. To set the switches, first switch the unit
Off, then position the DIP switches. After placing the switches in
the desired positions, switch the printer back on. The switch set-
tings are read by the printer electronics when the printer is switched
on again. They will not become effective until this has been done.
