adjusted as follows: When two

the rear

clear
the platen (Fig. 190). When
one tab card
is
placed

Paper Release - Adjust the feed roll release arm (Fig.
191)
to
obtain a release
clearance
of
.055"
to
.065"
between the rear feed roll
and
the
platen.

Excessive
clearance
can cause interference between the
front feed roll and
the
carrier; whereas insufficient
clearance
will not permit straightening
of
thick paper
packs. .
NOTE: The
clearance
should be the same
at
each
end
of the feed
roll.
The
clearance
can be
equalized
by
adjusting
either
the
left or right feed roll release lever
(Fig. 191).
