SECTION VI.
TYPE 122 PRINTER
adjustment control on the right side of the printer body.
Turning this cranklike control in a clockwise direction
moves all four tractors in unison to the right.
Counter-
clockwise rotation moves the tractors to the left.
h.
Position the form for proper vertical registration of the
printed output by turning the head-of -form control knob
located in the upper left area of the printing mechanism.
Clockwise rotation of the knob moves the printed output
up with respect to the form.
Adjust the knob so that the
first line to be printed coincides with the scribed line on
the paper guide.
'i.
Check that the LINES/INCH switch on the printer auxiliary
control panel is set for the desired vertical spacing, i. e. ,
either six or eight lines per inch.
The setting of this
switch must match the number of lines per inch (six or
eight) in the vertical format control tape being used; other-
wise, when the first head-of-form formatting instruction
is executed, the paper will feed continuously, resulting in
a runaway paper condition.
A runaway condition is normally
stopped by depressing the TYPE ROLL OFF button on the
main control panel of the printer.
If the runaway paper
condition is not stopped by pressing the TYPE ROLL OFF
button, the POWER OFF button on the main control panel
must be
pressed~
NOTE: If all the holes punched in the control tape are
opposite sprocket holes, the tape may be used for
either six- or eight-lines-per-inch vertical format-
ting, provided that no more than one hole is punched
opposite any given sprocket hole.
j.
Check the condition of the printer ribbon.
If a ribbon change
is required, proceed according to the ribbon change procedure
outlined on page 6 - 11.
2.
To perform an initial start procedure after the printer has been prepared for
normal operations as outlined in procedure one above:
a.
Depress the TYPE ROLL ON button on the main control panel
of the printer, if it is not already on.
This action energizes
the type roll motor.
There is an automatic delay of approxi-
mately three seconds before the printer logic can be precon-
ditioned.
This delay is to allow the type roll motor to reach
full velocity.
b.
Depress the START button to signal the printer control that the
printer is in a "ready" condition to receive a print instruction
from the central processor.
c.
If the speed of the type roll or the number of carbons in the
form have been changed, it is likely that a slight adjustment of
the character/index control will be required (see page 6-17).
