ADJUSTMENTS

This bulletin contains requirements

and

adjusting procedures for the

maintenance of Model

printers. Adjustments are arranged in a sequence that

would be followed if a complete readjustment of a unit were undertaken. In

following  such  a  procedure,  parts  or  assemblies  which  are  removed  to  facilitate
adjustment  should  not  be  replaced  until  all  other  adjustments  are  made  which
would  be  facilitated

the removal of these parts. If one adjustment is

changed, related adjustments should be checked because a change in one adjust

ment

may

affect related adjusbnents. These facts should be kept in mind when

a single adjustment is to be made.

The spring tension values given in this bulletin are scale reaaings

which should be obtained when Teletype scales are used as specified.

Springs

which do not meet the requirements specified and for which no adjus ting proced

ure is

n should

be rep

springs.

Ordering

information

.lll8IY'

obtained from

the

Teletype parts bulle tin.

Before proceeding

to adjust

any

read the description of the

a.cijustment carefully. After the adjustment is canpleted, be sure to tighten

aey

screws

or nuts which

I11BiY'

have· been loosened.

a part that is 100unted on

shims

is to be dismantled, the nwnber of shims used at each of its mounting

screws

should be noted so that

the

same shim pUe-ups can

be replaced

when

the

part is re�munted

•

Care should be exercised in removing or installing the cover

avoid

damaging parts in close proximit;r. As a precaution, raise or lower the cover

slo"fdy with a vertical movement.

NOTEt

In all figures of this bulletin, fixed pivot points are d esignated b7

MOTOR

SPEED

Synchronous motors do· not require governors because they are constant

speed motors. The speed of a governed motor may be checked by viewing the tar

get on the zootor governor through the vibrating shutters of a speed irrlicator

(

tuning fork

)

provided for this purpose.

With the motor running

and

the target well illuminated, tap the speed

indicator lig htly to

make

it vibrate and hold it so that the shutters are close

to the eye. If the zootor is running at the correct speed, the target will

appear stationary.

the motor speed is too fast, the target

will

appear to

be moving in the direction of rotation;

a.OO if

too slow, in the opposite

direction.

NOTE:

There is a possibility of setting the speed incorrectly, due to

getting a speed multiple; i.e., the speed could be half the desired
