CAUTION:
When locking screws are loosened to make
the U.C. armature stop adjustment, be careful not to dis-
turb the armature backstop adjustment.

UC Magnet Assembly - Position so that its mounting
screws are centered in the elongated holes with the hinge
plates parallel with the assembly mounting plate.
4.
LC Magnet Assembly - Position as follows:
a.
Front to Rear - LC armature (energized) clears the
UC armature (at rest) by .010
11
(Fig. 36).
This clearance insures unlatching of the upper case
armature.

UC armature (energized) clears the
LC armature (at rest) by .003" to .006

(Fig.

When the upper case armature is picked the lower
case armature must be able to snap forward and
latch the upper case armature. If the clearance is
excessive the upper case armature may move far e-
nough to a Ilow a shi ft to take place. When this hap-
pens the printer will be
in
lower case while the mag-
net assembly is latched in upper case.
