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 right 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 c$J Turning it with the power on could
damage the platen drive gears.
RELEASE LEVER - On top, near the left rear corner. You’ll
be using this particular control often. What it does is control the
pressure of the paper against the platen. Its position is crucial
to feeding the different paper types - sprocket and single sheets.
It has three settings: “Friction,
” “Set,” and “Tractor.” The first
two are used for single sheet printing, and the Tractor position
for sprocket paper. This will be fully explained in the section
describing paper loading procedures.
BAIL LEVER - The bail is the movable bar that presses the
paper against the platen during printing, and when moved away
from the platen, allows the paper to reach its proper position
during the loading operation. The lever which controls it is on
the right side of the platen.
PAPER-OUT DETECTOR - This sensor automatically stops
printing and tells you when the printer runs out of sprocket paper.
The paper-out lamp glows red and a beep tone alerts you when
the printer runs out of paper. The pause lamp also glows, so you
are ready to load more paper. The lamp also glows if the release
lever is not set in the tractor position for sprocket paper loading.
FRONT-COVER-OPEN DETECTOR - When the front cover
is not fully closed, this magnetic detector causes the pause lamp
to glow, and printing is interrupted (or won’t begin). If this
happens, printing may be re-started by securely closing the cover
and pressing the pause button.
DIP SWITCHES - Primarily, these switches are used in inter-
facing SR- 10/l 5 to your particular brand of computer. But there
are also switches to set the power-on default settings for print
style, and page size. See the appendix for a complete explanation.
