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 OJ’$ Turning it with the power on could
damage the platen drive gears.
