Switches -
(1) ON LINE
Pressing the "ON LINE" switch toggles the printer
between the two states of "on line" and "off line". The
present condition is indicated by the "ON LINE"
lamp.
While printing aline in the "line print" mode, the
printer can not be taken "off line". It can be taken "off
line" when the line feed (LF) signal is received after
completing aline of printing.
Depressing this switch does not interrupt the print-
ing of the self-test pattern.
(2) LINE FEED
Depressing this switch causes aone-line (1/6 inch)
paper feed. Continuous pressure on this switch
results in continuous paper feed.
(3) FORM FEED
Depressing this switch causes the paper to be ad-
vanced to the designated first line of the next page.
This paper advancement is accurate with paper
lengths of 11 or 12 inches only. Page length setting
is carried out by means of the DIP switch setting.
(See page 9, SW 3
)
(4) TOF SET
When the paper is set to the position desired by the
user as the first line, depressing the TOF SET switch
stores "top of form" information in memory. To
change the TOF SET position, move the platen to
the desired position and depress the switch. The old
TOF SET position is automatically cleared.
Without using the TOF SET switch, the TOF SET
position is set at the present printing position when
the power is turned on or when the paper is loaded
by means of the automatic paper insertion.
(5) Automatic Paper Insertion
Insert the paper in the back of the platen. Depress
the FORM FEED switch while depressing the TOF
SET switch, then the paper will automatically be fed
to the printing line approximately 1.0 inch (25mm)
from the upper edge of the paper.
Lamps-
(1) POWER
This lamp is lit when the power switch is on.
(2) ALERT
This lamp lights on the following occasions:
aThe ribbon is depleted.
«The top cover is opened.
eA"paper out" occurs with the optional form tractor
installed.
(3) ON LINE
This lamp indicates that the printer is ready for
printing. It is extinguished when:
1) The printer is taken "off-line" by means of press-
ing the "ON LINE" switch, or
2) ALERT condition exists.
In the former case, the printer is put back into a
"ready" condition by depressing the "ON LINE"
switch.
In the latter case, the fault condition must be cor-
rected first, and then the printer becomes ready for
printing by the depression of the "ON LINE" switch.
SELF-TEST
With the power switch off, depress the "LINE FEED"
switch and place the power switch to "ON" position.
Afive-line printout will occur. The power switch
must be toggled off and back on before normal
operation can be resumed. (See page 24)
