SECTION VI.
TYPE 122 PRINTER
a.
Determine the weight of the paper and the number of carbons to
be used in the printing run.
Set the stock thickness adjuster,
i. e., the lever on the right side of the printing mechanism, to
one of the five possible positions according to the thickness of
the paper and the number of carbons being used in the run.
Use
higher-numbered settings for thicker forms.
b.
Ensure that a sufficient supply of paper is available for printing
the run.
c.
Start the type roll by depressing the TYPE ROLL ON button on
the main control panel of the printer.
d.
Depress the FORM SPACE button on the main control panel of
the printer.
e.
Depress the TYPE ROLL OFF button on the main control panel
of the printer, and release the type roll housing by disengaging
the toggle clamp bar securing the housing.
Raise the type roll
housing.
£.
Lift the tractor cover plates on the upper and lower tractor pin
feeds on the left side of the printer.
Align the head of the form
with the scribed index mark on the paper guide and insert the
marginal punches of the form into the upper tractor.
Close the
upper tractor cover plate for form retention.
In the vicinity
of the lower tractor assembly on the left side, grasp the form
and gently pull it while mating the form with the pins on the
lower left tractor.
If the tractor pins and the holes in the form
do not match, turn the vertical paper-tension adjustment knob
in the lower left corner of the printing mechanism until the
paper and the tractor pins mate.
NOTE: Clockwise turning of the paper-tension adjustment
knob increases paper tension.
Drop the paper over the pins and close the tractor cover.
Determine whether the upper and lower tractors on the right
side of the printer need to be adjusted to accommodate the width
of the new form.
If a shift is necessary, individually adjust
the tractors to the correct position.
This adjustment may be
accomplished by two controls, permitting either a coarse or
a fine adjustment.
The quick-disconnect feature of the right-
side tractors may be used to obtain a coarse adjustment.
This
control is a button-like prominence on the handwheel attached to
the right-hand side of the tractor body.
Simply depressing this
button disengages the tractor from the shaft and allows the
tractor to be moved freely in either direction on the shaft.
When releasing this button, push the tractor slightly to the
right or the left to re-engage the button.
After obtaining a
coarse adjustment, lift the right-side tractor covers and insert
the marginal punches of the form into the tractor pin feeds.
A
fine adjustment may then be obtained by turning the knurled
vernier-adjusting handwheel on each of the right-side tractor
mechani sms.
g.
Horizonta~ly
adjust all four tractors jointly with respect to the
column scale.
This is necessary to establish the desired
marginal relationships for printing on the form.
The adjustment
is accomplished by turning the horizontal tractor-positioning
