Paper Release Adjustment
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.

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.

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.
