Figure 2-3. SG- lo/ 15’s controls.
POWER LAMP - Glows green
when the power is on.
READY LAMP - Glows green
when the printer is ready to ac-
cept data. This light flickers
during transmission. Don’t
worry about the flicker; it’s
normal!
ON LINE LAMP - Glows green
when the communication lines
to your computer are open.
PAPER-OUT LAMP - Glows
red when the printer is out of
paper and stops printing.
LF BUTTON - Stands for “Line
Feed,” and allows you to ad-
vance the paper one line at a time
when the on line lamp is off. If
you hold the button down, you’ll
get consecutive line feeds, one
after another.
FF BUTTON - Stands for
“Form Feed.” When you tap this
button while the on line lamp
is off, you advance the paper to
the top of a new page or “form.”
ON LINE BUTTON- Lets you change the printer status between -
“off line,” and “on line”. When it’s on line, the printer can receive
data from the computer. When it’s off line, the printer sends a
signal to the computer indicating that it cannot accept data. - -
When you turn the power switch on, you are automatically on
line.
There are other kinds of controls, not connected to the control
panel board. Some of the more important ones are:
POWER SWITCH - Towards the back on the left side. This
turns on the electricity to your machine.
PLATEN KNOB - Middle, right side. Lets you manually turn
the platen, just like a typewriter. CAUTION: Turn this knob
only with power switch off. Turning it with the power on could
damage the platen drive gears.
