Deflector - Position the deflector by forming the deflector
supporting tabs on the front and rear feed roll arms so
that a clearance of .010" to .020" exist between the
front and rear of the deflector and the platen (Fig. 184).
Three tab cards inserted between the platen and the de-
flector (at the front and rear) should provide a slight
drag. No drag should be felt when one tab card is in-
serted.
• 010" To .020"

9. Paper Bail
a. Bai I Shaft - The shaft should be positioned in the
right hand bai I arm so that each arm can be pulled
forward the same distance from the platen before the
entire bai I begins to move.
The ad justment insures that both bail rollers wi I r have
equal pressure against the platen.
CAUTION: Be sure that neither bail arm is de-
flected left or right after the bai I shaft is tightened.

b. Bai I Stop - The I ugs that stop the rearward movement
of the paper bail arms should be formed to obtain a
.005" to .010" clearance between the lugs and the
boil arms when the copy control lever is at its ex-
treme rear position.
The adjustment prevents interference between the
bai I arms and the I ine gage card holder when the
platen is removed.
10. Line Gage Card Holder
1.
a. Adjust the line gage card holder forward or back
for a .005" to .010" clearance with the platen.
b. The vertical ad justment should be such that the
graduated edge is parallel to and .002" to .005"
below the feet of the typed characters when viewed
from the operator1s position.
c. Adjust the card holder left or right so that the point
ofa letter "YII will al ign with the mark in the middle
of the I ine gage card holder.
FABRIC RIBBON MECHANISM
Centering Springs - With the ribbon reverse interposer
centered, form the lugsofthe ribbon feed plate for .003"
to .005" clearance in the centering spring loops (Fig.
185) .
The ad j ustment insures that the spri ngs are not extended
when at rest and that they will properly restore the mech-
anism after a reverse operation.
